The evolution of main sequence star + white dwarf binary systems towards Type~Ia supernovae
N. Langer, A. Deutschmann, S. Wellstein +1
Close binaries consisting of a main sequence star and a white dwarf are considered as candidates for Type~Ia supernova progenitors. We present selfconsistent calculations of the ti…

Mixing and nucleosynthesis in rotating TP-AGB stars
N. Langer, A. Heger, S. Wellstein +1
We present the first evolutionary models of intermediate mass stars up to their thermal pulses which include effects of rotation on the stellar structure as well as rotationally in…

Implications of massive close binaries for black hole formation and supernovae
S. Wellstein, N. Langer
The progenitor evolution of the massive X-ray binary Wray 977 is investigated using new models of massive close binary evolution. These models yield constraints on the mass limit f…
