The convective Urca process
P. Lesaffre, Ph. Podsiadlowski, C. A. Tout
One possible fate of an accreting white dwarf is explosion in a type Ia supernova. However, the route to the thermonuclear runaway has always been uncertain owing to the lack of a…
A two-stream formalism for the convective Urca process
P. Lesaffre, Ph. Podsiadlowski, C. A. Tout
We derive a new formalism for convective motions involving two radial flows. This formalism provides a framework for convective models that guarantees consistency for the chemistry…
Reconstructing the evolution of white dwarf binaries: further evidence for an alternative algorithm for the outcome of the common-envelope phase in close binaries
G. Nelemans, C. A. Tout
We determine the possible masses and radii of the progenitors of white dwarfs in binaries from fits to detailed stellar evolution models and use these to reconstruct the mass-trans…
Exploring the Divisions and Overlap between AGB and Super-AGB Stars and Supernovae
J. J. Eldridge, C. A. Tout
We discuss the mass ranges over which we find AGB and super-AGB stars. The most massive super-AGB stars are candidate progenitors for type II core-collapse SNe. We discuss the two…
Modelling the progenitors of Core-Collapse Supernovae
J. J. Eldridge, C. A. Tout
We present details of our investigation of the progenitors to core-collapse supernovae. We discuss observations and the theory of the lowest-mass stars to explode as supernovae.
HR4049: signature of nova nucleosynthesis ?
Maria Lugaro, Onno Pols, Amanda I. Karakas +1
The post-Asymptotic Giant Branch (AGB) star HR4049 is in an eccentric binary system with a relatively short period probably surrounded by a dusty circumbinary disk. Extremely anoma…
Stellar Chemical Signatures And Hierarchical Galaxy Formation
K. A. Venn, M. Irwin, M. D. Shetrone +3
ABRIDGED: To compare the chemistries of stars in the Milky Way dSph galaxies with stars in the Galaxy, we have compiled a large sample of Galactic stellar abundances from the liter…
Deep Dredge-up in Intermediate-Mass TP-AGB Stars
R. J. Stancliffe, C. A. Tout, O. R. Pols
We present results of the evolution of AGB stars of 3M_sol and 5M_sol with solar metallicity calculated with the Eggleton stellar evolution code (STARS), which has a fully implicit…
Detection of a red supergiant progenitor star of a type II-plateau supernova
S. J. Smartt, J. R. Maund, M. A. Hendry +4
We present the discovery of a red supergiant star that exploded as supernova 2003gd in the nearby spiral galaxy M74. The Hubble Space Telescope (HST) and the Gemini Telescope image…
