Seismic evolution of low/intermediate mass PMS stars

Astrophysics 2009-11-13 v1

Abstract

This article presents a study of the evolution of the internal structure and seismic properties expected for low/intermediate mass Pre-Main Sequence (PMS) stars. Seismic and non-seismic properties of PMS stars were analysed. This was done using 0.8 to 4.4M_\odot stellar models at stages ranging from the end of the Hayashi track up to the Zero-Age Main-Sequence (ZAMS). This research concludes that, for intermediate-mass stars (M>>1.3M_\odot), diagrams comparing the effective temperature (TeffT_{eff}) against the small separation can provide an alternative to Christensen-Dalsgaard (C-D) diagrams. The impact of the metal abundance of intermediate mass stars (2.5-4.4M_\odot) has over their seismic properties is also evaluated.
