Pulsating Hot Subdwarf Stars

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 spectroscopi...
