Special Universe Lecture: Predicting the radiative display of Type Ia Supernovae: 1. testing the standard model

by Stephane Blondin (Laboratoire d’Astrophysique de Marseille, France)

Thursday, 20 July 2017 from to (Europe/Berlin)
at Universe Cluster, Boltzmannstr. 2, Garching ( seminar room, basement )
Abstract: Stephane will present the numerical setup developed with his collaborators to predict the light curves and spectra of Type Ia supernovae (SNe Ia). These simulations are based on the 1D, non-LTE, time-dependent radiative transfer code CMFGEN. He will first consider the standard delayed-detonation explosion mechanism applied to Chandrasekhar-mass white dwarf stars. Then heI will show that their approach delivers an excellent agreement to observations, despite the 1D treatment, providing support to the viability of the standard Chandrasekhar-mass model. Stephane will discuss variations of this standard model involving a pulsation during the explosive phase, which could explain part of the observed diversity among SNe Ia.
