Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected a new low-mass, pre-main-sequence binary system. The newfound binary, designated 2M1222−57, contains two stars the size of the sun but ...
Researchers led by Ph.D. candidate Guo Yanjun from Yunnan Observatories of the Chinese Academy of Sciences (CAS) have explored the dependency of the intrinsic binary fraction on derived stellar effective temperature, metallicity ...

Indian astronomers have employed NASA's NuSTAR spacecraft to inspect an X-ray pulsar known as 1E 1145.1-6141. Results of the observations deliver important insights into the properties and nature of this pulsar. The study ...
An international team of astronomers has analyzed the photometric and spectroscopic observations of a candidate cataclysmic variable known as OGLE-BLG504.12.201843. Results of this analysis suggest that this object is an ...
Using data from various space telescopes, astronomers have investigated a variable X-ray source known as SWIFT J0503.7-2819. Results of the study suggest that this source is an intermediate polar. The finding was detailed ...
Using the Canadian Hydrogen Intensity Mapping Experiment (CHIME), astronomers have detected a new radio pulsar in a binary system with a massive non-degenerate companion star. The discovery of the pulsar, which received designation ...
Astronomers have conducted photometric and spectroscopic observations of a binary system known as TIC 60040774. Results of the observational campaign shed more light on the properties of this system, revealing that it is ...
What do UX Tauri, RW Aurigae, AS 205, Z CMajoris, and FU Orionis have in common? They're young stellar systems with disks where planets could form. It appears those disks were disturbed by stellar flybys or other close encounters ...
