Using multiple telescopes, astronomers have detected two new magnetic cataclysmic variable systems of the polar subclass and determined their fundamental properties. The finding, which could help us better understand the ...
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 ...
Using three ground-based telescopes in Chile, astronomers have conducted a search for variable stars in the open cluster NGC 6611. In result, they detected 95 variables and the majority of them are most likely cluster members. ...
Scientists try to unravel the birth, growth and power of black holes, some of the most forceful yet difficult-to-detect objects in our universe.
