An international team of astronomers has conducted spectroscopic and photometric observations of the young massive cluster NGC 1850 with the aim of investigating the effects of stellar rotation across its stellar population. ...
Black holes are the most extreme objects in the universe. Supermassive versions of these unimaginably dense objects likely reside at the centers of all large galaxies. Stellar-mass black holes—which weigh approximately ...

Using NASA's Swift telescope and the Neutron star Interior Composition Explorer (NICER) instrument onboard the International Space Station, Indian astronomers have inspected timing and spectral properties of an X-ray transient ...
By analyzing a large set of photometric data, astronomers have investigated KT Eridani—a nova detected in 2009. The study, published October 19 on arXiv.org, found that KT Eridani is a recurrent nova with a recurrence time-scale ...
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 the Caucasus Mountain Observatory, Russian astronomers have investigated a nearby lenticular galaxy known as NGC 4324. They detected young star-forming complexes in the inner ring of this galaxy. The findings, presented ...
Using various spacecraft and ground-based telescopes, astronomers have conducted multiwavelength observations of a Type IIn supernova known as SN 2017hcc. Results of the observational campaign, published October 6 on arXiv.org, ...
Using the Keck Observatory, astronomers from the Radboud University in the Netherlands and elsewhere have conducted spectroscopic observations of a young massive cluster known as NGC 1569-B. Results of the observational campaign, ...
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 ...
Using the AstroSat spacecraft, Indian astronomers have investigated an open cluster known as NGC 2506. The study identified more than 2,000 member stars of this cluster and provided more insights into its properties. The ...
