Stars may be tidally disrupted if, in a single orbit, they are scattered too close to a supermassive black hole (SMBH). Tidal disruption events are thought to power lumino us but short-lived accretion episodes that can light up otherwise quiescent SMBHs in transient flares. Here we exp lore a more gradual process of tidal stripping where stars approach the tidal disruption radius by stellar volution while in an eccentric orbit. After the onset of mass transfer, these stars episodically transfer… CONTINUE READING
