Direct diameter measurement of a star filling its Roche Lobe

Abstract

Context. Stellar evolution in close binary systems is strongly influenced by mass transfer from one star to the other when one component fills its zero-velocity surface or Roche Lobe. SS Lep is a fairly nearby close binary showing the Algol paradox and a shell spectrum, both indicative of (past) mass transfer. Aims. To study the process of mass transfer and… (More)
