An international team of astronomers reports the discovery of a new cataclysmic variable. The newfound system, designated SRGeJ041130.3+685350 (or SRGeJ0411 for short), has an orbital period of about 100 minutes and may contain ...
Astronomers from the Open University in Milton Keynes, UK and elsewhere report the detection of a new Be/X-ray binary. The newfound system, designated 4XMM J182531.5–144036, exhibits persistent X-ray emission. The finding ...
The desorption of CO ice induced by ultraviolet (UV) radiation is a phenomenon that occurs in some cold parts of the universe, which has often also been replicated in laboratory settings. While this phenomenon is now well-documented, ...
By analyzing the data from various space telescopes, astronomers have performed a detailed study of an ultraluminous X-ray source known as NGC 2403 XMM4. Results of the study, published January 5 in the Monthly Notices of ...
Astronomers have performed multiwavelength observations of a nearby M-dwarf star known as EV Lacertae (or EV Lac for short). The observational campaign resulted in the detection of a new large stellar flare from this object. ...
It's not every day astronomers say, "What is that?" After all, most observed astronomical phenomena are known: stars, planets, black holes and galaxies. But in 2019 the newly completed ASKAP (Australian Square Kilometer Array ...
