Modelling the evolution and nucleosynthesis of carbon-enhanced metal-poor stars
O. R. Pols, R. G. Izzard, M. Lugaro +1
We present the results of binary population simulations of carbon-enhanced metal-poor (CEMP) stars. We show that nitrogen and fluorine are useful tracers of the origin of CEMP star…
Thermohaline mixing and gravitational settling in carbon-enhanced metal-poor stars
Richard J. Stancliffe, Evert Glebbeek
We investigate the formation of carbon-enhanced metal-poor (CEMP) stars via the scenario of mass transfer from a carbon-rich asymptotic giant branch (AGB) primary to a low-mass com…
Evolution of stellar collision products in open clusters. II. A grid of low-mass collisions
E. Glebbeek, O. R. Pols
In a companion paper we studied the detailed evolution of stellar collision products that occurred in an -body simulation of the old open cluster M67 and compared our detailed m…
Evolution of stellar collision products in open clusters. I. Blue stragglers in N-body models of M67
E. Glebbeek, O. R. Pols, J. R. Hurley
Stellar collisions are an important formation channel for blue straggler stars in globular and old open clusters. Hydrodynamical simulations have shown that the remnants of such co…
The effect of massive binaries on stellar populations and supernova progenitors
John J. Eldridge, Robert G. Izzard, Christopher A. Tout
We compare our latest single and binary stellar model results from the Cambridge STARS code to several sets of observations. We examine four stellar population ratios, the number o…
When Stars Collide
E. Glebbeek, O. R. Pols
When two stars collide and merge they form a new star that can stand out against the background population in a starcluster as a blue straggler. In so called collision runaways man…
