As you know, there are dark spots on the surface of the Sun. The existence of huge persistent dark spots on the surface of young stars is also assumed.
There are bright areas on the Sun around sunspots – torches, where an influx of additional energy from the convective zone is observed. The brightest are areas of solar flares, which by their nature are explosions caused by the compression of solar plasma.
On pulsars, bright spots are the regions of the magnetic poles.
