      Article
      Accés obert
      Aims. Our main goals are to get a deeper insight into the evolution and final fates of intermediate-mass, extremely metal-poor (EMP) stars. We also aim to investigate the C, N, and O yields of these stars. Methods. Using ...

    • Explosion of white dwarfs harboring hybrid CONe cores 

      Bravo Guil, Eduardo; Gil Pons, Pilar; Gutiérrez Cabello, Jordi; Doherty, Carolyn L. (EDP Sciences, 2016-04-12)
      Article
      Accés obert
      Recently, it has been found that off-center carbon burning in a subset of intermediate-mass stars does not propagate all the way to the center, resulting in a class of hybrid CONe cores. The implications of a significant ...

    • Further evidence of the long-term thermospheric density variation using 1U CubeSats

      Article
      Accés obert
      The evolution of primordial stars of initial masses between 5 and 10 M⊙ has been computed and analyzed in order to determine the nature of the remnants of massive intermediate–mass primordial stars and to check the ...
