Using the ROentgen SATellite (ROSAT), astronomers have discovered a new cataclysmic variable system of the polar subtype. The new polar, which received the designation ZTF J0112+5827, has an orbital period of approximately ...

By analyzing multiwavelength data from various space telescopes and astronomical surveys, Chinese astronomers have explored the long-term variability of a blazar known as PKS 0727-11. Results of the new study, published in ...

Astronomers have performed a multiwavelength study of nine open cluster candidates. As a result, they found that all of them are genuine open clusters and characterized by their fundamental properties. The finding was reported ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has explored the atmosphere of a nearby brown dwarf binary designated WISE J045853.90+643451.9. As a result, they detected hydrogen cyanide ...

Chinese astronomers have analyzed the data from NASA's Swift observatory, which extensively observed an outburst of the cataclysmic variable system known as GK Persei. Results of the study, published February 20 on the arXiv ...

An international team of astronomers reports the discovery of a new dwarf galaxy, which they have named Pegasus VII. The newfound galaxy, which lies about 2.4 million light years away, was identified in the Ultraviolet Near-Infrared ...

Israeli astronomers report the detection of a new Jupiter-like exoplanet using the High Accuracy Radial velocity Planet Searcher (HARPS). The newfound alien world orbits a nearby M-dwarf star designated GJ 2126. The discovery ...

An international team of astronomers reports the detection of the first pulsar by the Globular Clusters GMRT Pulsar Search (GCGPS) survey. The pulsar, designated PSR J1617−2258A, was found in the globular cluster NGC 6093. ...

Using ESA's XMM-Newton satellite and NASA's Chandra X-ray observatory, astronomers have observed a young stellar object known as HL Tauri. Results of the observation campaign, presented Feb. 11 on the arXiv pre-print server, ...

Using the Special Astrophysical Observatory (SAO), Russian astronomers have carried out spectroscopic and photometric observations of a cataclysmic variable designated Gaia 19cwm, finding that it is a dwarf nova of the WZ ...

Astronomers from West Virginia University and elsewhere report the detection of 18 new pulsars using the Arecibo Observatory (AO) as part of the AO 327-MHz Drift Survey. The findings were detailed in a research paper published ...

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers have investigated the emission properties of three long-period pulsars. Results of the observational campaign are presented in a research ...

Using the X-ray Polarimetry Explorer (IXPE) and Neutron star Interior Composition Explorer (NICER), Indian astronomers have observed an X-ray binary system known as GX 9+1. Results of the observational campaign, presented ...

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) and by analyzing archival Arecibo Observatory data, astronomers have investigated a distant pulsar designated PSR B1310+18A. Results of the new study, ...

An international team of astronomers has investigated a newly detected Type II supernova designated SN 2024jlf. The new study, detailed in a paper published Jan. 30 on the arXiv pre-print server, yields important information ...
