| Program: | Horizont Európa |
| Project leader: | Mgr. Schwartz Pavol PhD. |
| Annotation: | This project aims to enhance FAIR (Findability, Accessibility, Interoperability, and Reusability) principles for archiving, curation and sharing of solar data through the SOLARNET Virtual Observatory (SVO), other astrophysical databases, and the ESCAPE-ESAP science platform. This is done by applying of standards established by the SOLARNET project and the International Virtual Observatory Alliance (IVOA) to existing data as well as to data-reduction pipelines of the future solar observations. This work will not only improve seamless access to data of already existing instruments through Virtual-Observatory (VO) tools, but will also support the future operations of the European Solar Telescope (EST), European largest solar telescope still in preparation. |

Dynamical versus generic relationship in the groups of small bodies in the Solar System
Dynamická verzus generická príbuznosť v skupinách malých telies v Slnečnej sústave
| Duration: | 1. 1. 2022 - 31. 12. 2025 |

| Project leader: | RNDr. Neslušan Luboš CSc. |
| Annotation: | In the studies of the parent bodies of meteor showers, it was revealed that two parent bodies, comet 96P and asteroid 196256, move in the orbits, which librate in almost identical phase space. Their current orbits are different. However, they periodically become almost identical and also the objects closely approach each other. Since the objects are different from the physical point of view, a reason for the similarity is unknown. A similar problem appears, however, also in the families of asteroids consisting sometimes of the members of different taxonomy class. In the project, we focuss our attention mainly to the problem whether the above-mentioned similarity can also occur, with a relatively high probability, as a consequence of the dynamical evolution of objects. Moreover, we will study further aspects of the dynamical evolution of small bodies in the Solar System. |
Extrasolar planets: an extrem case of interacting binary stars
Extrasolárne planéty: extrémny prípad interagujúcich dvojhviezd

| Project leader: | RNDr. Budaj Ján DrSc. |
| Annotation: | Interacting binary (IB) stars consist of two stars, often with vastly different masses, radii, and/or temperatures. They interact via gravity and irradiation. Planet-stars systems are subject to the same kind of interaction and could be considered an extreme case of IB stars. Improving our own tools developed originally for IB stars we will study mutual interaction of stars and exoplanets. Aim of a project is to model exoplanet transits including the gravity darkening of a rotating star to determine an inclination between the rotational and orbital axes; analyse properties of a few dust emitting exoasteroids orbiting stars like white dwarf WD1145; analyse and compare behaviour of the circumstellar and circumplanetary material in exoplanets and IB. For this purpose, we will use data from KEPLER, TESS, CHEOPS satellites, and our own spectroscopic and photometric observations. This project is also connected to the international projects: DWARF and DAAD project RGB->EHB. |
Physics of the solar atmosphere: spectroscopy, spectro-polarimetry, and numerical modelling of various phenomena occurring in the atmosphere of the Sun.
Fyzika slnečnej atmosféry: spektroskopia, spektro-polarimetria a numerické modelovanie javov v atmosfére Slnka.
| Duration: | 1. 1. 2024 - 31. 12. 2027 |
| Evidence number: | VEGA 2/0043/24 |
| Program: | VEGA |
| Project leader: | Mgr. Gömöry Peter PhD. |
| Annotation: | The atmosphere of the Sun is a unique laboratory for the research of physical processes that control the interaction between the plasma and magnetic field, which cannot be simulated in terrestrial conditions. The study of individual structures in the solar atmosphere also helps to better understand fundamental physical problems. Therefore, the goal of this project is to obtain fundamentally new knowledge about these features. For this purpose, high-precision imaging, spectroscopic and spectro-polarimetric observations obtained with high spatial and temporal resolution, will be used. Such data are necessary for the description of the continuously reorganizing and reconfiguring solar magnetic fields. In addition, experimental findings will be compared with results obtained from numerical modelling and simulations. This approach is currently necessary not only for the research of impulsive energy release in active regions but also for the study of quiet regions of the solar atmosphere. |
Physical and dynamical properties of Solar system small bodies as indicators of their origin and evolution
Fyzikálne a dynamické vlastnosti malých telies v Slnečnej sústave ako indikátory ich pôvodu a evolúcie
| Duration: | 1. 1. 2022 - 31. 12. 2025 |
| Evidence number: | VEGA 2/0059/22 |
| Program: | VEGA |
| Project leader: | Mgr. Husárik Marek PhD. |
| Annotation: | The project is dedicated to the study of physical properties of small Solar System bodies – relicts in which the matter of the primordial nebula is embedded. The study is focused on the search for correlations of their orbital characteristics and identification of properties associated with different regions of their origin and evolution. The study of comets and asteroids is important also because of their potential encounter with the Earth. To address this goal, it is necessary to: make comprehensive photometric, polarimetric, and spectroscopic observations of different dynamical groups; investigate dynamical relationships between different populations by modeling their orbital evolution; study the evolution and activity mechanisms over a wide spatial and temporal range; develop new and refine existing theoret. models to explain physical processes in comets, asteroids, and the meteoroid impacts into the Earth's atmosphere. Contribution by planned observations into international campaigns for space missions is possible. |

| Annotation: | Studying the dynamics and evolution of short-lived and high-speed chromospheric jets, commonly referred to as type II spicules, is an important and challenging research goal. Our statement, that chromospheric jets are dynamic plasma structures in the solar chromosphere and they play a significant role in energy transport, mass transfer, and heating processes in the solar atmosphere effectively conveys the importance of studying type II spicules, their relevance to energy transport and heating, their contribution to understanding solar plasma, and the challenges involved in comprehending their intricate behavior. By mentioning the Kelvin-Helmholtz Instability is indicated our understanding of the theoretical framework that may explain some of their dynamics. Hydrodynamic flows in the solar atmosphere can indeed be unstable, leading to various instabilities that play a crucial role in the behavior and dynamics of solar plasma. These instabilities are responsible for processes such as energy dissipation, heating, and particle acceleration, which have significant implications for the Sun-Earth connection and space weather. |
In2Ex - From Interacting Binaries to Exoplanets
Od interagujúcich hviezd k exoplanétam
| Duration: | 1. 7. 2021 - 30. 6. 2025 |
| Evidence number: | APVV-20-0148 |
| Program: | APVV |
| Project leader: | RNDr. Pribulla Theodor CSc. |
| Annotation: | Stars and stellar systems are the main field of research at our institute for more than half of a century. The aim of this project is to shift our focus towards the exoplanets. In fact, stars and exoplanets have a lot in common. They are often studied by similar methods of photometry and spectroscopy. Transit light curves are true analogues of eclipses in binaries and radial-velocity curves differ only in the amplitudes. Over the years we have developed the infrastructure and tools to study and model eclipsing binary stars. We aim to build upon these stepping stones and apply them to extrasolar planets. This transition will take years and during this period we will study interacting binaries and exoplanets simultaneously. We will attempt to advance the state-of-the art at several fronts including the search for disintegrating exoplanets and exoasteroids with dusty effluents, exoplanets around rapid rotators as well as cataclysmic variables at critical stages of their evolution. The goals of this project will be achieved by modelling observations of the investigated objects including multi-colour CCD photometry and échelle spectroscopy using advanced tools for their analysis. In addition to new observations obtained wit h the local facilities, the high-precision data from dedicated satellites (e.g., TESS, CHEOPS or Gaia) and large ground-based telescopes will be used. |

| Annotation: | Resonances play an important role in transporting objects from main asteroid belt to NEO (Near-Earth Object) region. The main goal of this project is to examine transportation abilities of the 3:1 mean motion resonance (MMR) with Jupiter, which belongs to the biggest contributors to the NEO population. For this purpose, N-body simulations will be used to simulate the motion in the Solar system. By complex mapping of the resonance with the chaos indicator FLI (Fast Lyapunov Indicator), we will focus primarily on unstable particles that will interact with the resonance with higher probability. Results of our simulations will be used to determine transportation abilities of the 3:1 MMR with Jupiter. These results will be also confronted with the list of meteorites with pedigree and the list of known potentially hazardous asteroids (PHAs) to estimate the amount of meteorites and PHAs that could originate in this resonance. |
