Using NASA's James Webb Space Telescope (JWST), astronomers have observed a nearby brown dwarf known as HD 19467 B. Results of the observational campaign, published January 26 on the arXiv pre-print server, yield important ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new warm brown dwarf. The newfound object, designated HIP 33609 b, transits a bright and rapidly rotating star. ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a peculiar cataclysmic variable star. The newly found system, designated SDSS J134441.83+204408.3 (or J1344 for short) is a highly asynchronous, ...
Using the Southern African Large Telescope (SALT), an international team of astronomers has discovered eight new very hot white dwarf and pre-white dwarf stars with effective temperatures over 100,000 K. The finding is reported ...
A team led by UdeM astronomers has found evidence that two exoplanets orbiting a red dwarf star are "water worlds," planets where water makes up a large fraction of the volume. These worlds, located in a planetary system ...

An international team of astronomers reports the detection of a new planetary system by observing a nearby star known as HD 18599 (or TOI-179). It appears that this star is orbited by a Neptune-mass exoplanet and a massive ...
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 ...
Astronomers report the detection of a new brown dwarf as part of the Ophiuchus Disk Survey Employing ALMA (ODISEA) program. The newfound object, designated SSTc2d J163134.1-24006, appears to be experiencing a quasi-spherical ...
Using data from ESA's XMM-Newton satellite and NASA's NuSTAR space observatory, Indian astronomers have performed a broadband X-ray analysis of a unique intermediate polar known as Paloma. Results of the study, published ...
