Astrosismología de estrellas variables Delta Scuti y Gamma Doradus
(Asociación Argentina de Astronomía, 2014-09)
En este trabajo presentamos resultados preliminares de la etapa inicial de un proyecto de gran magnitud consistente en el modelado teórico de estrellas variables Delta Sct y Gamma Dor. En esta primer etapa realizamos ...
On the use of rotational splitting asymmetries to probe the internal rotation profile of stars: Application to beta Cephei stars
(WILEY-V C H VERLAG GMBH, 2010)
Rotationally-split modes can provide valuable information about the internal rotation profile of stars. This has been used for years to infer the internal rotation behavior of the Sun. The present work discusses the potential ...
Asteroseismic inferences on GW Vir variable stars in the frame of new PG 1159 evolutionary models
(EDP Sciences, 2006-08)
An adiabatic, nonradial pulsation study of GW Vir stars is presented. The pulsation calculations were based on PG 1159 evolutionary sequences with different stellar masses artificially derived from a full evolutionary ...
Radial-velocity fitting challenge. II. First results of the analysis of the data set
(Edp Sciences, 2017-02)
Context. Radial-velocity (RV) signals arising from stellar photospheric phenomena are the main limitation for precise RV measurements. Those signals induce RV variations an order of magnitude larger than the signal created ...

Asteroseismology of hot pre-white dwarf stars: the case of the DOV stars PG 2131+066 and PG 1707+427, and the PNNV star NGC 1501
(EDP Sciences, 2009-05)
Aims. We present an asteroseismological study on the two high-gravity pulsating PG 1159 (GW Vir or DOV) stars, PG 2131+066 and PG 1707+427, and on the pulsating [WCE] star NGC 1501. All of these stars have been intensively ...
