    • Explaining the Type Ia supernova PTF 11kx with a violent prompt merger scenario 

      García-Berro Montilla, Enrique; Torres Gil, Santiago; Camacho Díaz, Judit; Soker, Noam; Kashi, Amit (2013-05)
      Article
      Accés obert
      We argue that the multiple shells of circumstellar material (CSM) and the supernovae (SNe) ejecta interaction with the CSM starting 59 d after the explosion of the Type Ia SN PTF 11kx are best described by a violent prompt ...
    • Factores subjetivos de la construcción sostenible. 

      Torres Gil, Santiago (2005-10-06T14:52:42Z)
      Article
      Accés obert
      El concepte de sostenibilitat requereix del concepte de societat sostenible. Quan ens referim a la sostenibilitat d'un sistema, ens referim a la d'un sistema humà, amb els seus aspectes materials i culturals, i que ha ...
    • Forever young white dwarfs: When stellar ageing stops 

      Camisassa, María Eugenia; Althaus, Leandro G.; Torres Gil, Santiago; Córsico, Alejandro H.; Rebassa Mansergas, Alberto; Tremblay, P. E.; Cheng, Sihao; Raddi, Roberto (EDP Sciences, 2021-05-01)
      Article
      Accés obert
      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. ...
    • Gaia 0007-1605: an old triple system with an inner brown dwarf-white dwarf binary and an outer white dwarf companion 

      Rebassa Mansergas, Alberto; Torres Gil, Santiago; Raddi, Roberto (Institute of Physics (IOP), 2022-03-15)
      Article
      Accés obert
      We identify Gaia 0007–1605 A,C as the first inner brown dwarf–white dwarf binary of a hierarchical triple system in which the outer component is another white dwarf (Gaia 0007–1605 B). From optical/near-infrared spectroscopy ...
    • Gaia DR2 white dwarfs in the Hercules stream 

      Torres Gil, Santiago; Cantero, Carles; Camisassa, María E.; Antoja, T.; Rebassa Mansergas, Alberto; Althaus, Leandro G.; Thelemaque, Thomas; Canovas Cabrera, Héctor (EDP Sciences, 2019-09-01)
      Article
      Accés obert
      We analyzed the velocity space of the thin- and thick-disk Gaia white dwarf population within 100 pc by searching for signatures of the Hercules stellar stream. We aimed to identify objects belonging to the Hercules stream, ...
    • General relativistic pulsations of ultra-massive ZZ Ceti stars 

      Córsico, Alejandro H.; Boston, Reece; Althaus, Leandro G.; Kilic, Mukremin; Kepler, Souza Oliveira; Camisassa, María Eugenia; Torres Gil, Santiago (Oxford University Press, 2023-10-01)
      Article
      Accés obert
      Ultra-massive white dwarf stars are currently being discovered at a considerable rate, thanks to surveys such as the Gaia space mission. These dense and compact stellar remnants likely play a major role in Type Ia supernova ...
    • High-proper-motion white dwarfs and halo dark matter 

      Torres Gil, Santiago; García-Berro Montilla, Enrique; Burkert, Andreas; Isern Vilaboy, Jordi (Blackwell, 2002-11)
      Article
      Accés obert
      The interpretation of the old, cool white dwarfs recently found by Oppenheimer et al. is still controversial. Whereas these authors claim that they have finally found the elusive ancienthalo white dwarf population that ...
    • Infrared-excess white dwarfs in the Gaia 100 pc sample 

      Rebassa Mansergas, Alberto; Solano Márquez, Enrique; Xu, Siyi; Rodrigo Blanco, Carlos; Jiménez Esteban, F. M.; Torres Gil, Santiago (Oxford University Press, 2019-11)

      Article
      Accés obert
      Magnetic activity and rotation are related to the age of low-mass main-sequence stars. To further constrain these relations, we study a sample of 574 main-sequence stars members of common proper motion pairs with white ...
