White dwarfs are the most common stellar evolutionary end-point. Moreover, they can be considered as reliable cosmic clocks to infer the age of a wide variety of stellar populations, including globular and open clusters. ...
Camacho Díaz, Judit (Date of defense: 2014-06-19)
Since white dwarfs are the final stage of the evolution of the vast majority of stars, they carry important information about the chemical evolution of our Galaxy, its star formation rate, and its structure and dynamics. ...
Portell i de Mora, Jordi (Date of defense: 2005-09-26)
Gaia, la nova missió astromètrica de la ESA amb un llançament previst pel 2011, observarà més de mil milions d'estels i altres objectes amb una exactitud sense precedents. Els seus ambiciosos objectius desbanquen completament ...
Torres Gil, Santiago (Date of defense: 2002-07-10)
El estudio de las propiedades de la población de enanas blancas de la Galaxia es muy amplio, e implica aportaciones en diferentes campos de la astrofísica, tales como evolución estelar, dinámica galáctica, ...
Catalán Ruiz, Sílvia (Date of defense: 2008-03-03)
White dwarfs are the final remnants of low- and intermediate-mass stars. About 95% of main- sequence stars will end their evolutionary pathways as white dwarfs and, hence, the study of the white dwarf population provides ...
Aznar Siguan, Gabriela (Date of defense: 2015-04-30)
Merging white dwarfs is a promising channel to trigger Type Ia supernovae, known as the double degenerate scenario. Supernovae are stellar explosions that radiate as much energy as any ordinary star is expected to emit ...
