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.

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 ...

Astronomers at the University of Toronto have discovered a population of massive stars that have been stripped of their outer hydrogen layer by companion stars. For over a decade, scientists have ...

An unusual binary system could be evidence that some massive stars can die ... The author worked with 50,000 stars from the Hipparcos astrometric catalog in hopes of fine-tuning earlier ...

On August 17th, both the light and the gravitational wave signals from inspiraling-and-merging neutron stars reached Earth, where both were detected, for the first time, by humans. The inspiral ...

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).

“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.” ...

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.
