Using the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST), astronomers have investigated a binary star known as TYC 2990-127-1. Results of the study suggest that this object is an Algol-type double-lined ...
Light on, light off—this is how one could describe the behavior of the nova, which goes by the name RS Ophiuchi (RS Oph). Every 15 years or so, a dramatic explosion occurs in the constellation of the Serpent Bearer. Birthplaces ...
