An international team of astronomers has conducted an astrometric and photometric wide-field study of the open cluster Messier 37. As a result, the researchers completed a comprehensive catalog of more than 200,000 sources ...
An international team of astronomers has studied variable broadband emission of the gamma-ray blazar Markarian 501 during a period of its high X-ray activity. The research, published January 21 on the arXiv preprint server, ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected solar-like oscillations and ellipsoidal variations in the light curve of a binary system known as 12 Boötis (or ...
Using NuSTAR spacecraft and the VERITAS array of telescopes, an international team of astronomers has investigated a gamma-ray binary known as HESS J0632+057. The study found that a compact object in this system is most likely ...
(Phys.org)—An international team of astronomers has recently detected two new so-called Be stars (non-supergiant stars with B spectral types and emission lines) residing in the open cluster NGC 6830, located some 5,300 ...
By analyzing data from ESA's XMM-Newton spacecraft and NASA's TESS telescope, German astronomers have inspected a highly variable polar known as V496 UMa. Results of the study, published May 20 on arXiv.org, deliver more ...
Using NASA's Fermi Gamma-ray Space Telescope, astronomers have collected important data that could disclose the real nature of the globular cluster Terzan 5. The new study, presented in a paper published May 24 on arXiv.org, ...
European astronomers have observed a source on the sky known as Gaia20eae, which recently entered a phase of significant outbursting activity. Results of the new study suggest that this source may be an EXor-type eruptive ...
