Seminarium "High Energy, Cosmology and Astro-particle Physics (HECA)"

White dwarfs constitute a fruitful environment to search for dark sectors, i.e. BSM physics. Their extreme conditions due to the high densities and temperatures in their cores together with the seemingly agreement in how to model them make them an ideal scenario for testing BSM models. Two specific models with dark photons will be shown: the Three portal model and Lμ - Lτ, both of which generate an extra contribution for the cooling of hot white dwarfs. For the latter, a first ever computed full calculation will be presented and discussed. Constraints found on the models will be also shown.
