Binary Star System with Millisecond Pulsar and a Helium Star Companion Discovered

Binary star system with millisecond pulsar and a helium star companion discovered

A large team of astronomers and astrophysicists affiliated with several institutions in China has discovered a binary star system, where one of the stars is a millisecond pulsar and the other is made mostly of helium. In their paper published in the journal Science, the group describes how they discovered that a pulsar under study since 2020 had a companion star—one that was gravitationally bound to it.

Chinese Astronomers Discover Rare Compact Binary System of Pulsar, Helium Star

Chinese Astronomers Discover Rare Compact Binary System of Pulsar, Helium StarChinese astronomers have discovered a rare compact binary system consisting of a millisecond pulsar and a companion helium star formed by common envelope evolution. This sheds light for future research on stellar evolution theory.The research, conducted by a team led by professor Han Jinlin from the National Astronomical Observatories of the Chinese Academy of Sciences…
