Phys.org / Long-term radio observations track the evolution of a tidal disruption event
Astronomers from Curtin University in Australia and elsewhere have performed radio observations of a tidal disruption event known as AT2019azh. Results of the new study, published September 22 on the arXiv preprint server, ...
Phys.org / Two Neptune-sized exoplanets discovered around a young sun-like star
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered two new exoplanets around a young sun-like star known as TOI-6109. The newfound alien worlds are slightly larger than Neptune and orbit ...
Phys.org / Rare nova super-remnant discovered in the Large Magellanic Cloud
Astronomers report the discovery of a rare nova super-remnant surrounding the recurrent nova LMCN 1971-08a in the Large Magellanic Cloud (LMC). This is the first nova super-remnant identified in the LMC. The findings are ...
Phys.org / Observations investigate a compact stellar system around nearby galaxy
An international team of astronomers has performed photometric and spectroscopic observations of a compact stellar system around a nearby spiral galaxy known as NGC 7531. Results of the observational campaign, published September ...
Phys.org / Star-forming cloud Sagittarius B2 explored with JWST
Using the James Webb Space Telescope (JWST), astronomers from the University of Florida and elsewhere have performed infrared observations of a star-forming cloud known as Sagittarius B2. Results of the observational campaign, ...
Phys.org / Observations explore a rare type Iax supernova
An international team of astronomers has conducted detailed multicolor photometric and spectroscopic observations of SN 2022xlp—a type Iax supernova. Results of the observational campaign, published September 9 on the arXiv ...
Phys.org / Astronomers detect a new black-widow pulsar
An international team of astronomers reports the discovery of a new "spider" millisecond pulsar, which received designation PSR J1544−2555. The finding was presented in a research paper published September 11 on the arXivpre-print ...
Phys.org / New radio halo discovered with MeerKAT
Using the MeerKAT radio telescope, an international team of astronomers has performed observations of a galaxy cluster designated SPT-CLJ2337−5942. The observational campaign revealed the presence of an ultra-steep spectrum ...
Phys.org / JWST observations discover a small star-forming complex
Using the James Webb Space Telescope (JWST), astronomers have detected what appears to be a faint and small star-forming complex. The discovery of the new complex, which received the designation LAP2, is detailed in a research ...
Phys.org / Observations investigate the nature of a newly discovered odd radio circle
Astronomers from Ruhr University Bochum in Germany and elsewhere have conducted radio spectropolarimetric observations of a recently identified odd radio circle designated ORC J0356–4216. Results of the observational campaign, ...
Phys.org / Second exoplanet found orbiting nearby star Gliese 536
Using radial velocity measurements, an international team of astronomers has identified a second planet orbiting a nearby M-dwarf star known as Gliese 536. The newfound alien world turns out to be at least a few times more ...
Phys.org / Discovery of young eclipsing binary system offers insight into early stellar evolution
An international team of astronomers reports the discovery of a new pre-main-sequence eclipsing binary system. The newfound binary, designated MML 48, consists of two young low-mass stars. The finding will be published in ...
Phys.org / White dwarf orbiting a blue straggler star detected
Using the Hubble Space Telescope (HST), Italian astronomers have observed five blue straggler stars in the globular cluster 47 Tucanae. Their results show that one of these stars has a white dwarf companion. The discovery ...
Phys.org / INTEGRAL observes exceptionally bright X-ray flares from Cygnus X-1
Using ESA's INTEGRAL spacecraft, astronomers have detected exceptionally bright X-ray flares from the Cygnus X-1 X-ray binary system. This is the first time that such strong flaring activity has been observed in this system ...
Phys.org / Astronomers map detailed structures in a giant radio fossil in the Ophiuchus cluster
Using the upgraded Giant Metrewave Radio Telescope (uGMRT), astronomers have performed radio observations of the Ophiuchus galaxy cluster. Results of the observations, published August 26 in The Astrophysical Journal, deliver ...
