Abstract:
With growing evidence for the existence of very massive stars at
subsolar metallicity, there is an increased need for corresponding
stellar evolution models. We present a dense model grid with a
tailored input chemical composition appropriate for the Large
Magellanic Cloud (LMC).
Description:
A dense model grid with chemical composition appropriate for the Large
Magellanic Cloud is presented. A one-dimensional hydrodynamic stellar
evolution code was used to compute our models on the main sequence,
taking into account rotation, transport of angular momentum by
magnetic fields and stellar wind mass loss. We present stellar
evolution models with initial masses of 70-500M☉ and with
initial surface rotational velocities of 0-550km/s.
