The quiescent states of V745 Sco and V3890 Sgr: VLT/X-shooter and Swift/XRT+UVOT observations
The episode reviews a study of V745 Sco and V3890 Sgr, two stars in the Galactic bulge. Using Swift and VLT observations, researchers found both systems show significant ultraviolet excess. This evidence indicates that steady, continuous mass transfer occurs at a rate of approximately five times ten to the power of negative eight solar masses per year, supporting a stable feeding process rather than sporadic bursts.
