Star classification often depends on the mass of these suns—the biggest burn hottest and brightest, while other types of stars are cooler and longer-lived.

The progenitor stars of type II supernovae are massive enough to fuse elements up to iron. But once iron is reached, fusion ceases and the star gravitationally implodes before violently exploding ...

Illogically, B-type stars are hotter and more massive than A-type, with temperatures between 10,000 K (9,727 °C or 17,540 °F) and 30,000 K (29,727 °C or 53,540 °F), but B is still the one ...

Characteristics Of K-type Stars. K-type stars have temperatures between 3,400° and 4,900° (6,152-8852° F). By comparison, the Sun’s temperature is 5,500° C, placing it in the middle of the G ...

The discovery of a metal-rich star packed with both light and heavy elements hints at exotic stellar explosions and the role of ancient dwarf galaxies in seeding the cosmos with uranium and thorium.

There are some stars of this type, known as red dwarfs, that have been around since nearly the beginning of our universe. “They just kind of hang out as stars,” Villar says. The next category of stars ...
