In the course of their evolution, white-dwarf stars go through at least one phase of variability in which the global pulsations they undergo allow astronomers to peer into their interiors, making it possible to shed light ...

In this chapter the equations of stellar structure are introduced. Up-to-date descriptions of the most relevant microphysics needed to build reliable stellar configurations are also provided. These include the equation of ...

Stars are extremely important astronomical objects that constitute the pillars on which the Universe is built, and as such, their study has gained increasing interest over the years. White dwarf stars are not the exception. ...

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 ...

Globular clusters have been used for a long time to test stellar evolution theories, and in particular to constrain novel forms of energy loss in low-mass stars. This includes constraints on axion properties, neutrino ...

White dwarf stars are the most common end point of stellar evolution. The ultramassive white dwarfs are of special interest as they are related to type Ia supernovae explosions, merger events, and fast radio bursts. ...

Presentamos observaciones polarimétricas lineales en las bandas UBV RI de 30 de las estrellas más brillantes en la dirección del cúmulo abierto NGC 6249. Los miembros del cúmulo son parte de dos subgrupos con valores ...
