Gamma Doradus Variable
Gamma Doradus Variable stars are a type of pulsating variable star that exhibit changes in brightness due to pulsations in their outer layers. These stars are typically located in the Doradus constellation and are classified as spectral type A or F. Their brightness variations occur over a period of several hours to a few days.
The pulsations in Gamma Doradus Variable stars are caused by the interplay of gravity and pressure in their interiors. This results in periodic expansions and contractions, leading to observable changes in luminosity. These stars are important for studying stellar structure and evolution, as they provide insights into the physical processes occurring within them.
