A large international team of astronomers has discovered the smallest known star to date, and found that it is paired with another, somewhat larger star. Their paper is published in the journal Nature Astronomy,.
Using ground-based telescopes, an international team of astronomers has observed a binary system containing at least one white dwarf, designated J0526+5934. The observational campaign has revealed that the binary is composed ...
In our most basic understanding of our solar system, planets are drawn into the orbit of our massive star, the sun. But what happens to planet-sized objects that don't have a star? A team of astronomers studying Jupiter-mass ...

Astronomers from Turkey and Russia have performed optical observations of a magnetic cataclysmic variable known as SRGA J213151.5+491400. Results of the observational campaign, presented Jan. 11 on the pre-print server arXiv, ...
An international team of astronomers reports the discovery of a new cataclysmic variable. The newfound system, designated SRGeJ041130.3+685350 (or SRGeJ0411 for short), has an orbital period of about 100 minutes and may contain ...
By investigating dwarf novae identified by the Zwicky Transient Facility (ZTF), astronomers have discovered four binary systems. The objects turned out to be eclipsing accreting ultracompact white dwarf binaries. The finding ...
Astronomers at the University of Toronto have discovered a population of massive stars that have been stripped of their hydrogen envelopes by their companions in binary systems. The findings, published in Science, shed light ...
