Using NASA's Hubble Space Telescope, Bucknell p hysics & astronomy Professor Katelyn Allers and postdoctoral researcher Blake Pantoja have observed an astronomical anomaly few have encountered before.

Astronomers have identified a rare type of binary star system containing a rapidly spinning millisecond pulsar and a helium star companion, formed via common envelope evolution. Although such systems ...

The Hubble Space Telescope has captured imagery of the R Aquarii binary star system from 2014-2023. The images have been time-lapsed here to show the evolution of the region. Credit: NASA, ESA, M.

A team of astronomers observed a confused exoplanet orbiting its two parent stars in a highly unusual way. As New Scientist reports, the planet, which was first discovered in 2004, is located in a ...

Stars are the fundamental building blocks of our universe. Most stars host planets, like our sun hosts our solar system, and if you look more broadly, groups of stars make up huge structures such as ...

In X-Ray binary systems, a compact object (like a Black Hole, a Neutron Star or a White Dwarf) usually rotates about an optical star. An X-Ray binary with a Neutron Star as the compact object can be ...

Rare star system This is the first time that a short-life binary consisting of a neutron star and a helium star has been detected. (Courtesy: Bureau of International Cooperation, Chinese Academy of ...

The binary star system ν Octantis has long been considered hostile to planet formation. The discovery of a white dwarf in the system offers an alternative view. However, Cheng and colleagues observe ...

A team of astronomers from The Graduate University for Advanced Studies, the National Astronomical Observatory of Japan, and other universities have captured the first direct image of a young binary ...

In theory, it could happen – one of the very first solutions to the three-body problem was this scenario. But it is very unlikely to be stable over time. You need the stars to have near equal mass and ...
