Abstract

The work systematizes and summarizes the main results of the studies of stars with solar-type activity: from the red and brown dwarfs to solar-like stars. The studies carried out primarily in the 2020s are reviewed, and the results obtained are grouped into the following sections: databases and catalogs, photospheres and starspots, rotation, chromospheres, coronae, flares, magnetic fields, activity cycles, and exoplanets.
