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 ...
Astronomers from the Open University in Milton Keynes, UK and elsewhere report the detection of a new Be/X-ray binary. The newfound system, designated 4XMM J182531.5–144036, exhibits persistent X-ray emission. The finding ...
A new study published in The Astrophysical Journal reveals new evidence for standard gravity breaking down in an idiosyncratic manner at low acceleration. This new study reinforces the evidence for modified gravity that was ...

Astronomers have conducted a photometric and spectroscopic study of an Algol-type binary, known as XZ Ursae Majoris (or XZ UMa for short). Results of the study, presented in a paper published December 21 on the pre-print ...
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 ...
Using the AstroSat spacecraft, astronomers from the Birla Institute of Technology and Science in Pilani, India, have investigated a nearby open cluster NGC 6940. Results of the observational campaign, published December 21 ...
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 ...
