Project

Variable stars in open clusters (7AMB12AT003)

The goal of the project is determination of the basic characteristics of open clusters using variable stars studies and furthermore testing of theories of stellar variability and stellar evolution as weel as constr...

Multispectral variability of hot stars and its nature (GAP209/12/0217)

became clearer when we applied advanced stellar model atmospheres to predict the light variability from spotted stellar surfaces. This came to the current paradigm for the nature of the light variability of these ...

Spectral energy distribution in chemically peculiar stars and its variability (MEB080832)

The aim of the project is the study of spectral energy distribution in Chemically peculiar (CP) stars and its variability. On-line database of photometric observations of these stars will be added by new observations in visual, IR and UV reg...

Stars in galactic nuclei interrelation with massive black holes (GM24-10599M)

The goal of the project is to study the mutual interaction between stars and supermassive black holes (SBHs) in galactic nuclei. Previously, we showed that the interaction with the nuclear jet can substantially affect stellar characteristics...

Atmospheres and circumstellar environment of magnetic hot stars (GA16-01116S)

Traditionally, the stellar mass is regarded as the main parameter that determines the stellar evolution. However, now it is clear that also other parameters, particularly magnetic field, influence many aspects of the stellar

MULTIPLE STELLAR SYSTEMS AS THE KEYS TO UNDERSTAND DYNAMICAL EVOLUTION OF STARS (GA15-02112S)

The proposed project represents a continuation and a significant extension of our previous systematic studies of multiple stellar systems and astrophysically interesting binaries. By combining complementary skills of the team members, we int...
