Özet

The photospheric temperature of active stars is affected by the contribution of surface features that are generally cooler than the surrounding photosphere. The knowledge of the starspot temperature and size is very important to understand the role and the effectiveness of the magnetic field in blocking the convective heating flux inside starspots. A reliable determination of the starspot temperature, however, is strongly hampered by the lack of solution uniqueness, as far as spot temperature and size are concerned.
