Stellar Spin Down in Post-Mass Transfer Binary Systems
Meng Sun, Seth Gossage, Emily M. Leiner +1
Motivated by measurements of the rotation speed of accretor stars in post-mass-transfer (post-MT) systems, we investigate how magnetic braking affects the spin-down of individual s…

Wind Roche-lobe Overflow in Low-Mass Binaries: Exploring the Origin of Rapidly Rotating Blue Lurkers
Meng Sun, Sasha Levina, Seth Gossage +4
Wind Roche-Lobe Overflow (WRLOF) is a mass-transfer mechanism proposed by Mohamed and Podsiadlowski (2007) for stellar binaries wherein the wind acceleration zone of the donor star…
