Vampire stars suck the life out of bright stars


Hugues Sana of the University of Amsterdam explains that the brightest stars in the universe are getting the life sucked out of them by vampire stars, also called O stars. According to researchers, a third of the vampire-victim pairs are eventually expected to merge and become one.

“These stars are absolute behemoths,” said Sana, lead author of this study. “They have 15 or more times the mass of our Sun and can be up to a million times brighter. These stars are so hot that they shine with a brilliant blue-white light and have surface temperatures over 54,000 degrees Fahrenheit.”
