A nonadiabatic oscillation study of DB white dwarfs
(EDP Sciences, 2002-01)
A self-consistent abundance diffusion treatment in the evolution of cooling white dwarfs permitted a study of the effect of elemental segregation in nonadiabatic, nonradial stability computations. In particular, mode ...
The Aarhus red giants challenge. I. Stellar structures in the red giant branch phase
(EDP Sciences, 2020-03)
Context. With the advent of space-based asteroseismology, determining accurate properties of red-giant stars using their observed oscillations has become the focus of many investigations due to their implications in a ...
Astrosismología de estrellas variables híbridas de secuencia principal
(Asociación Argentina de Astronomía, 2016-08)
Hybrid pulsating stars have an excellent asteroseismic potential since they show and -modes simultaneously excited, that allow to explore different regions of the stellar interior. In this study we present a theoretical ...
The rate of period change in pulsating DB white dwarf stars
(EDP Sciences, 2004-12)
In this work, we present the theoretically expected rates of pulsation period change for V777 Her (DBV) variable stars. To this end we employ new evolutionary models representative of pulsating DB white dwarf stars computed ...
The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA-derived Quantities, Data Visualization Tools, and Stellar Library
(2019)
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years of operation (2014 July-2017 July). This ...
