Annotation
Language of Thesis: English
Secondary language: Slovak
Affiliation: Astronomical Institute of the Slovak Academy of Sciences, Tatranská Lomnica, 059 60 Vysoké Tatry, Slovakia
Syllabus
Focus of the research: An analysis of the long-term observations of the solar activity – sunspots, photospheric magnetic fields as well as measurements of prominences and green corona, developed at the AISAS – for determination of behaviour and importance of manifestations of activity separately on individual hemispheres of the Sun. Searching for empirical implications for modeling of the solar activity by numerical methods describing the solar dynamo.
Objectives: An expected output of the research is determination of the temporal evolution of the time-latitude asymmetry of the solar activity for time period of several solar activity cycles and an analysis of its importance for different periods together with searching for probable periodicities of the activity.
Requirements:
English language, programming skills, physical background
Research field:
Research of physical properties and processes in the atmosphere of the Sun
