Ylva’ Götberg’s paper has been accepted for publication in the journal Astronomy and Astrophysics. Find a link to the forthcoming paper here. She computed the first tailor made models for the structure, evolution and atmospheres of the very hot stars that can from in binary systems when a star loses its envelope by interaction with a companion. She shows that these stars emit most of their light as ionizing photons, at wavelengths so short that none of the currently existing astronomical facilities can actually detect them. This first paper explores how metallicity affects these stars, i.e. are stripped stars in our own galaxy different from stripped stars that formed in the early days of the universe when there were less metals available? Stay tuned for more. Further papers to come out soon.
