Descripción
Hot subdwarf stars are core helium-burning objects, located at the hot end of the horizontal branch, and therefore, they are also known as Extreme Horizontal Branch stars. We can divide them into two large groups, of spectral types B and O, depending on their effective temperature. Each spectroscopic class has subgroups showing luminosity variations due to pulsations, opening the possibility to study these compact objects through Asteroseismology. In this notes I will briefly review the main characteristics of hot subdwarfs B and O stars and the different pulsating subgroups.
