Abstract

We present new stellar evolution models that show that the born-again phenomenon, also known as a very late thermal pulse, is a viable explanation for the behaviour of V838 Monocerotis if a period of accretion is included. Based on this model, we assert that V838 Mon is a variation of a born-again giant in close orbit with a main-sequence binary companion of mass greater than 0.7 M⊙.
