Semi-empirical versus Theoretical Stellar Population Models: a comparison with Star Clusters
Randa Asad, Paula R. T. Coelho, Johina M. John +3
Stellar population synthesis (SPS) models are a key tool for deriving the age, metallicity, radial velocity and reddening of star clusters from their integrated spectra. Using a sa…

A new prescription for the spectral properties of population III stellar populations
Marie Lecroq, Stéphane Charlot, Alessandro Bressan +7
We investigated various emission properties of extremely low metallicity stellar populations in the Epoch of Reionization (EoR), using the new GALSEVN model, which has shown promis…

Impact of accretion-induced chemically homogeneous evolution on stellar and compact binary populations
Marco Dall'Amico, Michela Mapelli, Giuliano Iorio +5
In binary star systems, mass transfer can spin up the accretor, possibly leading to efficient chemical mixing and chemically quasi-homogeneous evolution (CHE). Here, we explore the…
