Acoustic oscillations in M67 stars reveal a surprising plateau in frequency patterns, providing a new tool to probe stellar interiors and refine age estimates ...

Most stars in the Universe exist in binary or multiple star systems, where the presence of close-in companion stars in such systems can adversely influence the formation and orbital stability of ...

A planet twice the size of Jupiter has been confirmed in Nu Octantis. Its retrograde orbit and origin raise new questions about planetary formation in binary systems.

A small international team of astronomers has confirmed that a binary star system with an odd signal has a companion—a planet ...

The system ʋ Octantis (pronounced nu Octantis) should be hostile to planets. It contains a sub-giant star 57 percent heavier ...

Discovered in 1968, the system consists of a white dwarf and a red subgiant star. It erupts every four years, and its eruptions have been observed regularly since 1990. The most recent eruption ...

“Each frequency tells us more about the star’s size, chemical composition[,] and internal structure.” Setting out to study these songs, the authors of the new paper turned to Open Cluster M67, an area ...

This nova has a recurrent timescale of about four years — the third-shortest of any nova — and consists of a white dwarf and a companion red subgiant (a star much larger than the Sun).

Much longer than your wish needs to arrive at a star closer than 10,000 light years. The rest of the visible stars are what are called main sequence (or mid-life) stars and sub-giant stars.

The star in this system is a sub-giant star that is around five times as large as the sun with 15 times its brightness, though it is cooler and less dense than our star. The Gaia-BH3 companion ...
