Discovery and Classification of Variable Stars
This thesis investigates the classification of variable stars and the discovery of interesting behaviour in some of them. A secondary aim was to attempt to do this without astronomical expertise (domain knowledge). The data comes from the Macho dataset which consists of time series observations of the red and blue magnitudes of about 60 million stars, each observed approximately every night. Th...
متن کاملLINEAR PULSATION CHARACTERISTICS OF MIRA VARIABLE STARS
The linear adiabatic pulsation-periods of Mira variable stars have been derived. Approximately 2701[1]models were calculated for M = 0.7 MΘ to 2 MΘ stars with radii from 180 RΘ to 340 RΘ and luminosities from 2800 LΘ to 10,000 LΘ. The chemical composition of all models is (X,Z) = (0.7,0.02). From the result of this study, linear relations on Luminosity-Period-Mass relationship and luminosity-pe...
متن کاملThe Automated Detection and Classification of Variable Stars
Variable stars have been an incredibly important discovery since the early days of astronomy. Certain types of variable stars, such as Cepheids, can give not only great insight into the inner dynamics of stars, but also essential parameters of the star, such as luminosity, mass, and the distance from the observer. The number of discovered variable stars has risen dramatically over time, and sev...
