Context. The study of pulsation in pre-main-sequence intermediate mass stars represents an important tool for deriving information on the stellar parameters and structure, as well as for testing the validity of current theoretical models. The interest in this class of variable stars has significantly increased during the last decade and about 30 members are presently known in the literature. Aims. A new observational study of the Herbig Ae star VV Ser has been performed to detect and accurately… 

Searching for δ Scuti-type pulsation and characterising northern pre-main-sequence field stars

Context. Pre-main-sequence (PMS) stars are objects evolving from the birthline to the zero-age main sequence (ZAMS). Given a mass range near the ZAMS, the temperatures and luminosities of PMS and

Constraints on pre-main-sequence evolution from stellar pulsations

Abstract Pulsating pre-main-sequence (PMS) stars afford the earliest opportunity in the lifetime of a star to which the concepts of asteroseismology can be applied. PMS stars should be structurally

Parameters of Herbig Ae/Be and Vega-type stars ⋆

Context. This work presents the characterization of 27 young early-type stars, most of them in the age range 1‐10 Myr, and three ‐suspected‐ hot companions of post-T Tauri stars belonging to the

Comparing the Observational Instability Regions for Pulsating Pre-Main-Sequence and Classical δ Scuti Stars

A comparison of the hot and cool boundaries of the classical instability strip with observations has been an important test for stellar structure and evolution models of post- and main-sequence

Grids of stellar evolution models for asteroseismology (cesam + posc)

In this paper we present a grid of stellar evolution models, computed with an up-to-date physical description of the internal structure, using the Code d’Évolution Stellaire Adaptatif et Modulaire

Matching the frequency spectrum of pre‐main sequence stars by means of standard and rotating models

We applied the ATON evolutionary code to the computation of detailed grids of standard (non-rotating) and rotating pre-main sequence (PMS) models and computed their adiabatic oscillation spectra,

Planets of young stars: The TLS-Tautenburg radial velocity survey

The discovery and characterization of planets of young stars represents an important goal as it will allow to put much stronger observational constraints on the current theories of planet formation
