The Colloquium takes place every Wednesday at 11:15 AM - Warsaw Copernicus Astronomical Centre online by means of Zoom platform. The Colloquium is given in English and chaired by dr Stanisław Bajtlik (bajtlik@camk.edu.pl). People from outside of the Copernicus Center are very welcome to participate. For technical detailes please contact Dr. Stanislaw Bajtlik.

Magnetic activity in late-type stars includes a variety of phenomena driven by the interaction between convection, rotation, and magnetic field generation. Using the Sun as a reference, I will discuss how the physical processes change as we look at lower-mass, faster-rotating stars. This includes the transition from partially to fully convective stars, occurring around spectral types M3–M4. I will present results from starspot modeling of active late-type stars, comparing spot temperatures, sizes, and distributions with those of the Sun. Finally, I will focus on stellar flares, which are the most energetic expressions of magnetic activity. I will demonstrate how flare occurrence, energy, and physical parameters can differ from the values seen in the Sun.
Journal Club takes place on Mondays at 11:15 AM in the Seminar Room. The presentation is given in English and is chaired by Journal Club Coordinators. Anyone interested in giving a Journal Club talk is encouraged to contact the email: journalclub(@camk.edu.pl).
