Stellar spectral classification utilizes seven main classes (O, B, A, F, G, K, M), ordered by decreasing surface temperature, with each class further subdivided into numerical subclasses (0-9) ...
Stellar color is primarily determined by the star's surface temperature; hotter stars emit more blue light, while cooler stars emit more red light, mirroring the behavior of a propane flame. Stars are ...
Astronomers have discovered the first pairs of white dwarf and main sequence stars -- 'dead' remnants and 'living' stars -- in young star clusters. This breakthrough offers new insights on an extreme ...
