Companion Stars of Type Ia Supernovae
Zhanwen Han
The WD+MS channel of the single-degenerate scenario is currently favourable for progenitors of type Ia supernovae (SNe Ia). Incorporating the results of detailed binary evolution c…
Simple Stellar Population Models as probed by the Large Magellanic Cloud Star Cluster ESO 121-SC03
Y. Xin, L. Deng, R. de Grijs +2
The presence of blue straggler stars (BSs) in star clusters has proven a challenge to conventional simple stellar population (SSP) models. Conventional SSP models are based on the…
The Impact of Type Ia Supernova Explosions on their Companions in Binary System
X. Meng, X. Chen, Z. Han
Using a simple analytic method, we calculate the impact effect between the ejecta of a SN Ia and its companion to survey the influence of initial parameters of the progenitor's sys…
The blue stragglers formed via mass transfer in old open clusters
B. Tian, L. Deng, Z. Han +1
In this paper, we present the simulations for the primordial blue stragglers in the old open cluster M67 based on detailed modelling of the evolutionary processes. The principal ai…
Constraints on SN Ia progenitor time delays from high-z SNe and the star formation history
F. Förster, C. Wolf, Ph. Podsiadlowski +1
We re-assess the question of a systematic time delay between the formation of the progenitor and its explosion in a type Ia supernova (SN Ia) using the Hubble Higher-z Supernova Se…
Evolutionary and pulsational properties of low-mass white dwarf stars with oxygen cores resulting from close binary evolution
L. G. Althaus, A. H. Corsico, A. Gautschy +3
The present work is designed to explore the evolutionary and pulsational properties of low-mass white dwarfs with carbon/oxygen cores. In particular, we follow the evolution of a 0…
