  • Oxygen-neon-rich merger during common envelope evolution 

    Canals, Pere; Torres Gil, Santiago; Soker, Noam (Oxford University Press, 2018-11-01)
    Article
    Accés obert
    We conduct a population synthesis study of the common envelope evolution (CEE) of a white dwarf (WD) and an asymptotic giant branch (AGB) star and find that the potential number of type Ia supernovae (SNe Ia) from the core ...
  • On the parallelization of stellar evolution codes 

    Martin Rodriguez, David; José Pont, Jordi; Longland, Richard Leigh (Springer (Biomed Central Ltd.), 2018-11-01)
    Article
    Accés obert
    Multidimensional nucleosynthesis studies with hundreds of nuclei linked through thousands of nuclear processes are still computationally prohibitive. To date, most nucleosynthesis studies rely either on hydrostatic/hydrodynamic ...
  • The scatter of the M dwarf mass-radius relationship 

    Parsons, S. G.; Gänsicke, Boris T.; Marsh, T. R.; Rebassa Mansergas, Alberto (Oxford University Press, 2018-11-21)
    Article
    Accés obert
    M dwarfs are prime targets in the hunt for habitable worlds around other stars. This is due to their abundance as well as their small radii and low masses and tempera- tures, which facilitate the detection of temperate, ...
  • A white dwarf catalogue from Gaia-DR2 and the Virtual Observatory 

    Jiménez Esteban, F. M.; Torres Gil, Santiago; Rebassa Mansergas, Alberto; Skorobogatov, G.; Cantero, C. (Oxford University Press, 2018-01-01)
    Article
    Accés obert
    We present a catalogue of 73¿221 white dwarf candidates extracted from the astrometric and photometric data of the recently published Gaia-DR2 catalogue. White dwarfs were selected from the Gaia Hertzsprung–Russell diagram ...
  • Observational constraints on the age-metallicity relation from white dwarf-Main sequence binaries 

    Rebassa Mansergas, Alberto; García-Berro Montilla, Enrique; Torres Gil, Santiago; Anguiano, B.; Manser, C. J.; Gänsicke, Boris T.; Liu, X. (Astronomical Society of the Pacific Conference Series (ASP), 2017)
    Article
    Accés obert
    The age-metallicity relation (AMR) is a fundamental observational property to understand how the Galactic disc formed and evolved chemically in time. However, there is not yet a consensus on the observed properties of the ...
  • Science with e-ASTROGAM: a space mission for MeV–GeV gamma-ray astrophysics 

    De Angelis, Alejandro; Tatischeff, Vincent; Grenier, Isabelle A.; José Pont, Jordi (2018-08-01)
    Article
    Accés obert
    e-ASTROGAM (‘enhanced ASTROGAM’) is a breakthrough Observatory space mission, with a detector composed by a Silicon tracker, a calorimeter, and an anticoincidence system, dedicated to the study of the non-thermal Universe ...
  • Surface and core detonations in rotating white dwarfs 

    García Senz, Domingo; Cabezón Gómez, Rubén Martín; Domínguez, I. (Institute of Physics (IOP), 2018-07-20)
    Article
    Accés obert
    The feasibility of the double detonation mechanism—surface helium detonation followed by complete carbon detonation of the core—in a rotating white dwarf with mass ;1Me is studied using three-dimensional hydrodynamic ...
  • White dwarf-main sequence binaries from LAMOST: the DR5 catalogue 

    Ren, J. J.; Rebassa Mansergas, Alberto; Parsons, S. G.; Liu, X. W; Luo, Jun; Kong, X; Zhang, C. (Oxford University Press, 2018-07-01)
    Article
    Accés obert
    We present the data release (DR) 5 catalogue of white dwarf–main sequence (WDMS) binaries from the Large sky Area Multi-Object fibre Spectroscopic Telescope (LAMOST). The catalogue contains 876 WDMS binaries, of which 757 ...
  • The population of single and binary white dwarfs of the Galactic bulge 

    Torres Gil, Santiago; García-Berro Montilla, Enrique; Cojocaru, Elena Ruxandra; Calamida, Annalisa (Oxford University Press, 2018-05-01)
    Article
    Accés obert
    Recent Hubble Space Telescope observations have unveiled the white dwarf cooling sequence of the Galactic bulge. Although the degenerate sequence can be well fitted employing the most up-to-date theoretical cooling sequences, ...
  • Axions and the luminosity function of white dwarfs : the thin and thick discs, and the halo 

    Isern Vilaboy, Jordi; García-Berro Montilla, Enrique; Torres Gil, Santiago; Cojocaru, Elena Ruxandra; Catalán, S (Oxford University Press, 2018-08-01)
    Article
    Accés obert
    The evolution of white dwarfs is a simple gravothermal process of cooling. Since the shape of their luminosity function is sensitive to the characteristic cooling time, it is possible to use its slope to test the existence ...
