RW Tri

An Eclipsing Cataclysmic Variable Star

RW Trianguli (RW Tri) is a cataclysmic variable star in the constellation Triangulum. It is a binary system consisting of a white dwarf and a red dwarf, between which a continuous mass transfer takes place. RW Tri is a classic example of a nova-like variable star with an accretion disk.
