One such example is a star in a binary or multi-star system that accretes mass from a companion. With all that extra mass to burn, it can seem younger than its true age, appearing bluer and brighter.

Astronomers have discovered a population of massive stars that have been stripped of their hydrogen envelopes by their companions in binary systems. The findings shed light on the hot helium stars ...

Eventually, every stellar civilization will have to migrate to a different star. The habitable zone around all stars changes as they age. If long-lived technological civilizations are even ...

For example, most gold was created by stars similar to the supernova relic or neutron star in the binary system that we studied. Astronomy deepens our understanding of the world and our place in ...

They can also develop independently from star formation, for example around binary stars of which one is dying (binary stars are two stars that orbit each other, also called a binary system).

Stars have magnetic fields that initially get stronger as the speed of the star’s rotation increases. There are still aspects of this astronomers don’t understand, but the mystery turns out to ...

A: Yes, planetary systems can exist in binary star systems. As of July 2019, astronomers have found 97 planetary systems containing 143 planets around binary stars.

A newly designed, AI-powered program could solve the puzzle of binary stars in mere seconds using a common laptop, a process that currently takes supercomputer clusters weeks.

For example, oxygen comes almost entirely from massive stars, most of which explode, ... The cosmic carbon footprint of massive stars stripped in binary systems. arXiv:2110.04131.

“We have these binary stars orbiting each other in front of us, and not doing what Newton said they should be doing,” says Hernandez. “Not considering modified gravity is no longer an option.” ...
