"New Cataclysmic Variables Unveiled by Astronomers"
Originally Published 2 years ago — by Phys.org
An international team of astronomers has discovered eight new cataclysmic variables (CV) systems using the latest phase of the Sloan Digital Sky Survey (SDSS). CVs are binary star systems consisting of a white dwarf primary that is accreting matter from a normal star companion. SDSS-V contains a program to deliberately target white dwarfs and cataclysmic variable systems, which led to the discovery of these new CVs. Out of the eight newly discovered cataclysmic variables, four turned out to be WZ Sagittae (WZ Sge) systems—non-magnetic CVs showcasing low accretion rate and rare superoutbursts.
