Revisiting the pre-main-sequence evolution of stars [PDF]
Astronomy & Astrophysics, 2017 Aims. We want to investigate how planet formation is imprinted on stellar surface composition using up-to-date stellar evolution models. Methods. We simulate the evolution of pre-main-sequence stars as a function of the efficiency of heat injection ...

The evolution of supermassive Population III stars [PDF]
, 2017 Supermassive primordial stars forming in atomically-cooled halos at $z \sim15-20$ are currently thought to be the progenitors of the earliest quasars in the Universe. In this picture, the star evolves under accretion rates of $0.1 - 1$ $M_\odot$ yr$^{-1}$

Towards a better understanding of the evolution of Wolf–Rayet stars and Type Ib/Ic supernova progenitors [PDF]
, 2017 Hydrogen-deficient Wolf-Rayet (WR) stars are potential candidates of Type Ib/Ic supernova (SN Ib/Ic) progenitors and their evolution is governed by mass loss.

The VLT-FLAMES survey of massive stars: evolution of surface N abundances and effective temperature scales in the Galaxy and Magellanic Clouds [PDF]
, 2007 We present an analysis of high resolution VLT-FLAMES spectra of 61 B-type stars with relatively narrow-lined spectra lo cated in 4 fields centered on the Milky Way clusters; NGC3293 & NGC4755 and the Large and Small Magellanic cloud clusters; NGC2004 and

Core-Collapse Very Massive Stars: Evolution, Explosion, and Nucleosynthesis of Population III 500-1000 M☉ Stars [PDF]
, 2005 We calculate evolution, collapse, explosion, and nucleosynthesis of Population III very massive stars with 500 and 1000 M☉. Presupernova evolution is calculated in spherical symmetry. Collapse and explosion are calculated by a two-dimensional code, based

Evolution of asymptotic giant branch stars. II. Optical to far-infrared isochrones with improved TP- [PDF]
, 2007 We present a large set of theoretical isochrones, whose distinctive features mostly reside on the greatly-improved treatment of the thermally-pulsing asymptotic giant branch (TP-AGB) phase.

Evolution of binary stars and the effect of tides on binary populations [PDF]
, 2002 We present a rapid binary-evolution algorithm that enables modelling of even the most complex binary systems. In addition to all aspects of single-star evolution, features such as mass transfer, mass accretion, common-envelope evolution, collisions ...

The dragon simulations: globular cluster evolution with a million stars [PDF]
, 2016 Introducing the dragon simulation project, we present direct N-body simulations of four massive globular clusters (GCs) with 106 stars and 5 per cent primordial binaries at a high level of accuracy and realism.

THE SOLITON STARS EVOLUTION [PDF]
, 1996 The evolution of a soliton star filled with fermions is studied in the framework of general relativity. Such a system could be described by the surface tension σ0, the bag constant B, and the fermion number density ρ.

Mass Loss: Its Effect on the Evolution and Fate of High-Mass Stars [PDF]
, 2014 Our understanding of massive star evolution is in flux due to recent upheavals in our view of mass loss and observations of a high binary fraction among O-type stars.
