WebThe 7 Main Spectral Types of Stars. There are 7 main spectral types of stars — O (Blue), B (Blue), A (Blue), F (Blue/White), G (White/Yellow), K (Orange/Red) and M (Red). The stars are classified based on their temperature, with the hottest being O and the coolest being M. The temperature of each spectral class is then subdivided by the ... WebThe long-term lightcurve of T Tauri (see the AAVSO Lightcurve Generator) shows that variability takes place over several time scales. The overall long-term trend shows that the star brightened a bit in 1967, followed by a slight dip, with a return to the brighter state in 1984. On a short-term basis, the star varies by a few tenths on nearly a ...
