Unstable Mass Transfer from a Main-sequence Star to a Supermassive Black Hole and Quasiperiodic Eruptions by Itai Linial, Re’em Sari

“…We discuss the formation and evolution of systems composed of a low-mass ( M _⋆ ≲ 4 M _⊙ ) main-sequence star orbiting a 10 ^5 –10 ^7 M _⊙ supermassive black hole with an orbital period of order ∼hours and a mild eccentricity ( e ≈ 0.1–0.2), episodically shedding mass at each pericenter passage. …”

TWO SCENARIOS OF MASS EXCHANGE IN CLOSE BINARY SYSTEMS CONSISTING OF THE LOW MASS PRE-MAIN SEQUENCE STARS by F. V. Sirotkin

“…In this paper, we present the results of smoothed particle hydrodynamic (SPH) simulations of mass transfer in close binary systems consisting of the low mass pre-main sequence stars. Two scenarios of mass exchange in such systems are possible. …”
