    • 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
      Open Access
      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 ...
    • 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
      Open Access
      We analyse the 100¿pc Gaia white dwarf volume-limited sample by means of VOSA (Virtual Observatory SED Analyser) with the aim of identifying candidates for displaying infrared excesses. Our search focuses on the study of ...
    • Random Forest identification of the thin disc, thick disc, and halo Gaia-DR2 white dwarf population 

      Torres Gil, Santiago; Cantero, C.; Rebassa Mansergas, Alberto; Skorobogatov, G.; Jiménez Esteban, F. M.; Solano Márquez, Enrique (Oxford University Press, 2019-03-13)
      Article
      Open Access
      Gaia-DR2 has provided an unprecedented number of white dwarf candidates of ourGalaxy. In particular, it is estimated thatGaia-DR2 has observed nearly 400 000 ofthese objects and close to 18 000 up to 100 pc from the Sun. ...
    • The Gaia white dwarf population within 100 pc of the Sun 

      Torres Gil, Santiago; Rebassa Mansergas, Alberto; Jiménez Esteban, F. M.; Cantero, C.; Canals, Pere; Skorobogatov, G.; Solano, E (2018)
      Conference report
      Open Access
      The recent Gaia Data Release 2 has provided an unprecedented sample of the local white dwarf population. The high astrometric resolution and the photometry provided by Gaia allows to build a clean magnitude-color diagram ...
