An international team of astronomers reports the discovery of a new ultracompact binary of the AM CVn type exhibiting infrequent outbursts. The detection of the newfound system, designated TCP J07222683+6220548, was detailed ...

Astronomers from the Yunnan University in China and other institutions have carried out photometric and spectroscopic observations of a recently detected supernova designated SN 2024aecx. Results of the observational campaign, ...

Based on time-series photometry from three different telescopes, an international team of astronomers has performed a detailed asteroseismology study of WD J0049−2525—the most massive pulsating white dwarf. The study, published ...

Using the Magellan Clay Telescope, astronomers have performed a spectroscopic study of blue straggler stars in the globular cluster NGC 3201. Results of the new study, published May 21 on the arXiv preprint server, could ...

An international team of astronomers has discovered 25 new quasars by analyzing multiwavelength data from various surveys. All the newfound quasars were detected at redshifts greater than 4.6. The findings are detailed in ...

Using the Hubble Space Telescope (HST), astronomers have observed a globular cluster known as NGC 1754 as part of a systematic study of the most massive and compact clusters in the Large Magellanic Cloud (LMC). Results of ...

Using the James Webb Space Telescope (JWST), astronomers from Johns Hopkins University (JHU) and elsewhere have detected water ice in a debris disk around HD 181327—a young star located within 160 light years away from the ...

An international team of astronomers reports the discovery of a new giant exoplanet around an M-dwarf star (GEMS). The newfound GEMS, designated TOI-5573 b, is comparable in size to Saturn and its mass is estimated to be ...

An international team of astronomers using the Einstein Probe reports the discovery of a new peculiar fast-evolving X-transient. The newfound transient exhibits an unprecedented long-lasting X-ray emission. The finding was ...

Using various ground-based and space telescopes, an international team of astronomers has observed a highly variable young star known as DR Tauri. Results of the observational campaign, published May 12 on the arXiv preprint ...

Astronomers have employed NASA's Transiting Exoplanet Survey Satellite (TESS) and the Very Large Telescope (VLT) to conduct a detailed study of a chemically peculiar star known as HD 72968. Results of the study, published ...

An international team of astronomers reports the discovery of a new supernova remnant that showcases a remarkable circular symmetry in shape. The detection of the remnant, dubbed "Teleios," is described in a research paper ...

Using a set of ground-based radio telescopes, an international team of astronomers has observed a slowly-spinning pulsar known as PSR J0901−4046. Results of the observational campaign, published on the arXiv preprint server, ...

Using the Spektr-RG (SRG) space observatory, astronomers from the Russian Academy of Sciences have investigated dozens of X-ray sources in all-sky surveys, which resulted in the detection of 11 new active galactic nuclei. ...

An international team of astronomers reports the discovery of two new exoplanets, a few times more massive than Earth, orbiting a sun-like star known as HD 35843. The finding was reported in a research paper published May ...
