Rotational mixing in close binaries
S. E. de Mink, M. Cantiello, N. Langer +5
Rotational mixing is a very important but uncertain process in the evolution of massive stars. We propose to use close binaries to test its efficiency. Based on rotating single ste…
Orbital eccentricities of binary systems with a former AGB star
A. A. Bonacic Marinovic, E. Glebbeek, O. R. Pols
Many binary stellar systems in which the primary star is beyond the asymptotic giant branch (AGB) evolutionary phase show significant orbital eccentricities whereas current binary…
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…
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…
Building Blue Stragglers with Stellar Collisions
E. Glebbeek, O. R. Pols
The evolution of stellar collision products in cluster simulations has usually been modelled using simplified prescriptions. Such prescriptions either replace the collision product…
Critically rotating stars in binaries - an unsolved problem -
S. E. de Mink, O. R. Pols, E. Glebbeek
In close binaries mass and angular momentum can be transferred from one star to the other during Roche-lobe overflow. The efficiency of this process is not well understood and cons…
Common Envelope Evolution: Where we stand and how we can move forward
N. Ivanova, S. Justham, X. Chen +16
This work aims to present our current best physical understanding of common-envelope evolution (CEE). We highlight areas of consensus and disagreement, and stress ideas which shoul…
Gravitational settling in pulsating subdwarf B stars and their progenitors
Haili Hu, E. Glebbeek, A. A. Thoul +4
Diffusion of atoms can be important during quiescent phases of stellar evolution. Particularly in the very thin inert envelopes of subdwarf B stars, diffusive movements will consid…
The Puzzling Frequencies of CEMP and NEMP Stars
O. R. Pols, R. G. Izzard, E. Glebbeek +1
We present the results of binary population simulations of carbon- and nitrogen-enhanced metal-poor (CEMP and NEMP) stars. We show that the observed paucity of very nitrogen-rich s…
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…
The evolution of runaway stellar collision products
E. Glebbeek, E. Gaburov, S. E. de Mink +2
In the cores of young dense star clusters repeated stellar collisions involving the same object can occur, which has been suggested to lead to the formation of an intermediate-mass…
