Gamma Doradus is the third brightest star in the constellation of Dorado. It has an apparent visual magnitude of approximately 4.25 and is a variable star, the type star of the class of Gamma Doradus variables. These stars, like Doradus, are pulsating variables which vary in brightness by less than a tenth of a magnitude owing to nonradial gravity wave oscillations. The magnitude of Doradus itself has been observed to have two sinusoidal variations with periods of…mehr

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Gamma Doradus is the third brightest star in the constellation of Dorado. It has an apparent visual magnitude of approximately 4.25 and is a variable star, the type star of the class of Gamma Doradus variables. These stars, like Doradus, are pulsating variables which vary in brightness by less than a tenth of a magnitude owing to nonradial gravity wave oscillations. The magnitude of Doradus itself has been observed to have two sinusoidal variations with periods of approximately 17.6 and 18.2 hours. There is also some additional unexplained, apparently random fluctuation.
