Astronomers have conducted spectroscopic observations of the cataclysmic variable ES Ceti, which resulted in uncovering important insights about gas emission from this object. The new findings, presented in a paper published ...
Most stars with the mass of the sun or larger have one or more companion stars, but when and how these multiple stars form is one of the controversial central problems of astronomy. Gravity contracts the natal gas and dust ...
