The dynamic and magnetic environment of arch filament systems
Dynamika a magnetické vlastnosti oblúkovitých filamentárnych štruktúr
Program: Inter-academic agreement
Project leader: Mgr. Gömöry Peter PhD.
Annotation:The main goal of the project is to investigate together the dynamic and magnetic environment of solar arch filament systems (AFSs). An AFS is a system of relatively cool loops observed in the chromosphere of the Sun. The loops presumably trace the magnetic field lines. AFSs appear in emerging flux regions where different polarities of the magnetic field interact. To carry out the project we aim to combine two German high-resolution telescopes, namely the Vacuum Tower Telescope (VTT) and GREGOR located on the island of Tenerife (Spain), with the new Solar Chromospheric Detector (SCD) attached to the telescope at Lomnicky Peak of the High Tatra Mountains, Slovakia. The aim of this project is to observe AFSs simultaneously in different atmospheric layers to derive plasma flows and the magnetic field configuration across the atmosphere. This can be achieved combining different telescopes and instruments. SCD together with the German telescopes offer great potential to better understand the formation, evolution, and disappearance of AFSs. The study of loop systems in the atmosphere is a major topic in solar physics which has direct consequences for modelling of solar chromospheric features, eruptions, and the solar dynamo itself.

European Collaborating Astronomer ProjectS: Espana-Czechia-Slovakia
Európsky projekt spolupráce astronómov: Španielsko-Česko-Slovensko
Program: Multilateral - other
Project leader: Mgr. Jakubík Marián PhD.
Annotation:We aim at educating and fomenting the development of new leaders in astronomical research as achieved by international mobilities. Furthermore, we intend to educate our early career researchers in topics of astronomy which are active areas of research at partner institutes. In addition, we will disseminate our know-how to external audiences by organizing scientific seminars streamed live, by publishing scientific papers on hot topics in astronomy and by organizing international summer schools for early career researchers. We would like to include also an educational component by including pupils project work on selected astronomical topics which will implant a positive image of natural sciences and strengthen ties between scientific researchers and schools. Finally, the last component of our project will be a series of public lectures aimed at a broad audience, which will provide a valuable and rewarding connection between researchers and the general public.

Photometric and spectroscopic study of exoplanetary candidates
Fotometrický a spektroskopický výskum kandidátov na exoplanéty
Program: Inter-academic agreement
Project leader: Mgr. Hambálek Ľubomír PhD.
Annotation:This project deals with the detection and following characterization of exoplanetary candidates found by missions Kepler, K2, TESS, and projects Dwarf and YETI. The confirmation of discovery of an exoplanet needs long-term photometric and spectroscopic monitoring of the parent system. The analysis consists of measuring the changes in radial velocities (confirmation of candidates) and a subsequent analysis of the system (orbital parameters, minimal mass of the exoplanet); and a multi-color photometry (stellar and exoplanetary physical parameters).

Physical Properties of Solar Chromospheric Small-Scale Jets
Fyzikálne vlastnosti maloškálových výtryskov v slnečnej chromosfére
Program: Inter-academic agreement
Project leader: Mgr. Koza Július PhD.
Annotation:The solar chromosphere forms a dynamic interface between the cold photosphere and hot corona. High-resolution observations show that the chromosphere is populated with jet-like structures. They may contribute to the heating of the chromosphere and may supply required heat and mass to the corona. The aim of this project is to explore mechanisms of chromospheric and coronal heating by finely-structured jets and generation of plasma outflows. To accomplish this aim we combine high-resolution observations obtained by the CRISP/SST and IRIS instruments with cloud modelling of jets and their 2-fluid numerical simulations performed by the code JOANNA.
Duration: 1.1.2019 - 31.12.2022
Integrating High Resolution Solar Physics
Integrácia slnečnej fyziky s vysokým rozlíšením
Program: Horizon 2020
Project leader: Mgr. Gömöry Peter PhD.
Annotation:This project aims at integrating the major European infrastructures in the field of high-resolution solar physics. The following actions will be taken: (i) realise transnational access to all European users; (ii) integrate small communities and foster European collaboration; (ii) enhance and spread data acquisition and processing expertise to the Europe-wide community; (iii) increase the impact of high-resolution data by offering science-ready data and facilitating their retrieval and usage; (iv) encourage combination of space and ground-based data by providing unified access to pertinent data repositories; (v) foster synergies between observational and theoretical research communities by organising meetings where each presents stateof-the-art methodologies; (vi) train a new generation through student schools, a mobility program, and grant program to attend conferences; (vii) develop innovative post-focus instrumentation; (viii) develop and build next generation devices to correct for atmospheric turbulence; (ix) lay foundations for combined use of synoptic and high-resolution facilities on ground and in space (x) dissemination activities towards society. The project involves all pertinent European research institutions, infrastructures, and data repositories. Together, these represent first-class facilities. The additional participation by private companies and non-European research institutions maximizes the impact on the world-wide scale. In particular, the project achievements will be of principal importance in defining the exploitation of the future 4-meter European Solar Telescope.

Magnetoacoustic waves and dynamics of selected magnetic/plasma structures observed in solar active regions
Magnetoakustické vlny a dynamika vybraných magnetických/plazmových štruktúr pozorovaných v slnečných aktívnych oblastiach
Program: Inter-academic agreement
Project leader: RNDr. Rybák Ján CSc.
Annotation:The project is aimed at studying the characteristic physical parameters and interconnections among the selected magnetic (plasma) structures that occur in active regions of the solar atmosphere. Physical parameters of a 'drivers' triggering the explosive events, penumbral activity, turbulent plasma regions, relations between the observed structures and chromospheric/coronal heating, the flare generation and associated high-energy mass outflows will be studied together with the impulsive generated magnetoacoustic wave trains and their waveguides. The multi-wavelengths data with high spatial and temporal resolution acquired by ground-based (e.g., Ondřejov radiospectrographs, GREGOR) as well as space-born (e.g., SDO/AIA/HMI, IRIS, STEREO/SECHHI) be used. The project results will be published in international peer-reviewed journals and presented at international conferences.

Modelling of solar prominence fine structures using simultaneous SUMER and IRIS UV spectroscopy of hydrogen and magnesium lines
Modelovanie prenosu žiarenia v jemnej štruktúre slnečných protuberancií s využitím simultánnej spektroskopie UV čiar vodíka a horčíka získanej kozmickými spektrografmi SUMER a IRIS
Program: Inter-academic agreement
Project leader: Mgr. Schwartz Pavol PhD.
Annotation:Solar prominences are cloud-like structures formed by cool and dense plasma surrounded by hot and rarefied corona. They remain stable for extended periods of time, but may become unstable and erupt violently forming Coronal Mass Ejections (CMEs). CMEs eject large amounts of plasma into the interplanetary space. This ionized, high-velocity matter may hit the Earth and cause wide-scale disruptions to the satellites, communication networks and power grids. Therefore, better understanding of prominences, composition of their plasma, and configuration of their magnetic field is one of the key topics of solar physics today. This project aims to advance the curent 2D radiative transfer modelling of the prominence fine-structures by extending its recent version for hydrogen also to ionised magnesium. Such technique will for the first time allow us to analyze unique simultaneous UV spectral observations in both hydrogen and magnesium lines. These observatios were obtained by cosmic spectrographs SUMER/SoHO and IRIS.

Preparatory Phase for the European Solar Telescope.
Prípravná fáza pre Európsky slnečný ďalekohľad.
Program: Horizon 2020
Project leader: Mgr. Gömöry Peter PhD.
Annotation:The European Solar Telescope (EST) will be a revolutionary Research Infrastructure that will play a major role in answering key questions in modern Solar Physics. This 4-meter class solar telescope, to be located in the Canary Islands, will provide solar physicists with the most advanced state-of-the-art observing tools to transform our understanding of the complex phenomena that drive the solar magnetic activity. The principal objective of the present Preparatory Phase is to provide both the EST international consortium and the funding agencies with a detailed plan regarding the implementation of EST. The specific objectives of the proposed preparatory phase are: 1) to explore possible legal frameworks and related governance schemes that can be used by agencies to jointly establish, construct and operate EST as a new research infrastructure, with the implementation of an intermediate temporary organisational structure, as a previous step for future phases of the project; 2) to explore funding schemes and funding sources for EST, including a proposal of financial models to make possible the combination of direct financial and in-kind contributions towards the construction and operation of EST; 3) to compare the two possible sites for EST in the Canary Islands Astronomical Observatories and prepare final site agreements; 4) to engage funding agencies and policy makers for a long-term commitment which guarantees the construction and operation phases of the Telescope; 5) to involve industry in the design of EST key elements to the required level of definition and validation for their final production; 6) to enhance and intensify outreach activities and strategic links with national agencies and the user communities of EST.

Evolution pathways for blue horizontal branch stars
Vývoj horúcich podtrpaslíkov
Program: Inter-academic agreement
Project leader: Mgr. Kundra Emil PhD.
Annotation:We link blue horizontal branch (BHB) objects with their progenitors that are currently on the red giant branch (RGB). The spectroscopic observations taken by instruments at AISAS will be modeled by the stellar and binary evolution code MESA. The goal is to derive general model of interactions in the RGB stars. The model focused on the physical principles behind the interactions, will allow us to predict the observed population of BHB.
