Glacial lakes form when meltwater is trapped behind a dam, usually glacial ice, bedrock or a type of moraine (terminal types being an unconsolidated pile of debris at the maximum extent of the glacier). When a dam fails, ...
Using various ground-based facilities and space telescopes, astronomers have observed an accretion outburst that recently occurred on a young variable star known as V1741 Sgr. Results of the observations, published January ...
By analyzing the data from the SPICY catalog and from NASA's WISE spacecraft, an international team of astronomers has discovered four new eruptive young stellar objects (YSOs). The finding was presented in a research paper ...
Astronomers from the Liverpool John Moores University have performed photometric and spectroscopic observations of a recently discovered nova, known as AT 2023prq. Results of the observational campaign, published in the November ...
By conducting a blind search for large amplitude mid-infrared variables in the Wide Infrared Sky Explorer (WISE) archive, Chinese astronomers have serendipitously discovered a giant mid-infrared outburst from a distant young ...
Using the Neutron star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), European astronomers have performed spectral analysis of a low-mass X-ray binary known as XTE J1810–189. Results ...
An international team of astronomers has investigated EX Lupi—a young T-Tauri star in the constellation of Lupus and an archetype of EXor stars. The study, presented in a paper published August 23 on the pre-print server ...
An international team of astronomers has performed high-cadence optical monitoring of an active galaxy known as Markarian 1018. Results of the observational campaign, published July 26 on the pre-print server arXiv, shed ...
Using the Neutron Star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), an international team of astronomers has detected millihertz quasi-periodic oscillations from a low-mass X-ray binary ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), Chinese astronomers have detected quasi-periodic oscillations (QPOs) in the light curve of HS 2325+8205—a long-period eclipsing dwarf nova. The discovery was detailed ...
