Short period contact binary systems of the W Ursae Majoris (W UMa) type represent a significant fraction of eclipsing binaries observed in the Galaxy 1,2. These systems typically consist of two ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a peculiar cataclysmic variable star. The newly found system, designated SDSS J134441.83+204408.3 (or J1344 for ...
Astronomers have performed photometric observations of a young globular cluster known as NGC 1851. The new observational campaign provides more insights into the variable star population of this ...
We present the first results from Citizen ASAS-SN, a citizen science project for the All-Sky Automated Survey for Supernovae (ASAS-SN) hosted on the Zooniverse platform. Citizen ASAS-SN utilizes the ...
Variable stars, notably Cepheids and RR Lyrae, pulsate due to cyclic ionisation of helium in their envelopes, driving periodic expansions and contractions. These pulsation dynamics trace stellar ...
