Phys.org / Observations detect a new long-period radio transient associated with supernova remnant G22.7-0.2
Using the DAocheng Radio Telescope (DART), Chinese astronomers have detected a long-period transient event. The newfound transient, which received designation DART J1832-0911, has a period of approximately 44 minutes and ...
Phys.org / Observations shed more light on the properties of three-planet system TOI-396
An international team of astronomers has investigated a planetary system consisting of three alien worlds orbiting the star TOI-396. The study, published Nov. 22 on the pre-print server arXiv, provides the first mass measurements ...
Phys.org / Astronomers investigate the evolution of a supersoft X-ray source
Using ESA's XMM-Newton satellite and NASA's Chandra spacecraft, German astronomers have observed a supersoft X-ray source designated RX J0513.9−6951. Results of the observations, published on the arXiv preprint server, shed ...
Phys.org / Webb observations explore the Westerlund 1 star cluster
An international team of astronomers has employed the James Webb Space Telescope (JWST) to observe a supermassive Galactic open cluster known as Westerlund 1. Results of the observational campaign, presented in a paper published ...
Phys.org / Observations detect the lowest mass ratio contact binary to date
Astronomers from China and South Korea report the detection of a contact binary system with an extremely low mass ratio of only 0.0356. The newfound system, which received the designation TYC 3801-1529-1, is therefore the ...
Phys.org / Astronomers discover a rare group of dwarf galaxies
Astronomers from the Yonsei University in Seoul, South Korea and elsewhere have discovered a rare isolated group of five star-forming dwarf galaxies in the local universe. The finding was reported in a research paper published ...
Phys.org / Astronomers detect a distant young super-Jupiter exoplanet
An international team of astronomers has reported the detection of a new super-Jupiter exoplanet as part of the Next Generation Transit Survey (NGTS). The newfound alien world, located some 1,430 light years away, is nearly ...
Phys.org / Observations inspect double-lined spectroscopic binary HD 34736
Using various telescopes, an international team of astronomers has conducted a comprehensive study of a double-lined spectroscopic binary known as HD 34736. The study, published November 6 in the Monthly Notices of the Royal ...
Phys.org / New giant radio galaxy discovered with MeerKAT
An international team of astronomers has employed the MeerKAT radio telescope to investigate giant radio galaxies in the field of the Cosmological Evolution Survey (COSMOS). They found a new giant radio galaxy that had not ...
Phys.org / Astronomers discover a unique quasi-stellar object–dusty star-forming galaxy system
Astronomers from the Steward Observatory in Arizona and elsewhere report the discovery of a structure consisting of a quasi-stellar object (QSO) and a dusty star-forming galaxy (DSFG), linked by a bridge of ionized carbon. ...
Phys.org / Astronomers inspect the nature of an X-ray binary with a red supergiant
An international team of astronomers has conducted a multiwavelength study of an X-ray binary designated 1eRASS J085039.9-421151. Results of the study, published Nov. 4 on the preprint server arXiv, yield new information ...
Phys.org / Observations explore icy protoplanetary disk of the star PDS 453
Using ESO's Very Large Telescope (VLT), an international team of astronomers has inspected an icy protoplanetary disk of a young star known as PDS 453. Results of the new study, published on the preprint server arXiv, yield ...
Phys.org / Astronomers investigate long-term variability of blazar AO 0235+164
Astronomers have performed a comprehensive multiwavelength study of an extremely variable blazar known as AO 0235+164. Results of the new study, published Nov. 3 on the preprint server arXiv, shed more light on the long-term ...
Phys.org / Quasi-periodic eruptions from eRO-QPE2 are remarkably stable, study finds
An international team of astronomers has inspected long-term evolution of quasi-periodic eruptions (QPEs) from a QPE source designated eRO-QPE2. The study found that QPEs from this source are remarkably stable over the investigated ...
Phys.org / Astronomers discover a new repeating fast radio burst
Using the CHIME telescope, an international team of astronomers has detected a new repeating fast radio burst (FRBs) source in the outskirts of a quiescent galaxy. The finding of a new FRB, which experienced 22 repeating ...
