Giovedì 5 maggio alle ore 15:00, il Dr. Emanuele Tognelli dell’ Institute of Physics of the Czech Academy of Sciences di Praga (Czech Republic), terrà il web-seminar dal titolo: Effects of protostellar accretion on the pre-MS and MS evolution of low-mass stars.

Abstract

This talk is focused on the effects caused by the inclusion of protostellar accretion in the evolution of low-mass stars. First, I will briefly introduce the main characteristics of the protostellar accretion, focusing on two different scenarios: 1) disk and 2) spherical accretion. Then, I will discuss the role of the main parameters that characterize the protostellar accretion phase, such as the initial seed mass/radius, accretion rate, accretion energy, deuterium abundance, and their impact in the predictions of theoretical models. I will also briefly discuss how the comparison with observations (photometry and/or surface chemical abundances) could help in constraining such parameters in the new generation of stellar models.
