Ylva Götberg


My name is Ylva and I work on interacting binary stars. Currently, I am a PhD student working with Dr. Selma E. de Mink at Anton Pannekoek Institute for Astronomy, University of Amsterdam, The Netherlands.


I am interested in the interaction that happens in binary stars. I model the evolution and spectra of stars that lose their envelope through mass transfer in binary systems. For this, I use the binary stellar evolutionary code MESA (Paxton et al. 2011, 2013, 2015) and the non-LTE, radiative transfer code CMFGEN (Hillier & Miller 1998). The models provide observable features, which we use in search for more stripped stars. I work in close collaboration with Dr. José H. Groh.


In about a year, I will graduate and is therefore looking for a next career step.



The BinCosmos project                                   logo_bin

In the BinCosmos project we work to establish the significance of binary stars throughout cosmic time. My role stretches from nearby stellar population up to high redshift.

We are part of Selma de Mink's group working theoretically on binary stars in Amsterdam.

We work with various codes:

  • Binary stellar evolution with MESA
  • Model stellar atmospheres with CMFGEN
  • Binary population synthesis with binary_c
