    • A population synthesis fitting of the Gaia resolved white dwarf binary population within 100 pc 

      Torres Gil, Santiago; Canals Canals, Pere; Jiménez Esteban, F. M.; Rebassa Mansergas, Alberto; Solano Márquez, Enrique (Oxford University Press, 2022-04-01)
      Article
      Open Access
      The Gaia mission has provided an unprecedented wealth of information about the white dwarf population of our Galaxy. In particular, our studies show that the sample up to 100\,pc from the Sun can be considered as practically ...

    • 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. ...

    • Spectral classification of the 100 pc white dwarf population from Gaia-DR3 and the virtual observatory 

      Jiménez Esteban, F. M.; Torres Gil, Santiago; Rebassa Mansergas, Alberto; Cruz Gamba, Patricia; Murillo Ojeda, Raquel; Solano Márquez, Enrique; Rodrigo Blanco, Carlos; Camisassa, María Eugenia (Oxford University Press, 2023-02-01)
      Article
      Open Access
      The third data release of Gaia has provided low resolution spectra for 100 000 white dwarfs (WDs) that, together with the excellent photometry and astrometry, represent an unrivalled benchmark for the study of this ...

    • 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 ...

    • White dwarf spectral type-temperature distribution from Gaia DR3 and the Virtual Observatory 

      Torres Gil, Santiago; Cruz Gamba, Patricia; Murillo Ojeda, Raquel; Jiménez Esteban, F. M.; Rebassa Mansergas, Alberto; Solano Márquez, Enrique; Camisassa, María Eugenia; Raddi, Roberto; Doliguez Le Lourec, J. (EDP Sciences, 2023-09-21)
      Article
      Open Access
      Context. The characterization of white dwarf atmospheres is crucial for accurately deriving stellar parameters such as effective temperature, mass, and age. However, the inclusion of physical processes such as convective ...

    • White dwarf-main-sequence binaries from Gaia EDR3: The unresolved 100 pc volume-limited sample 

      Rebassa Mansergas, Alberto; Solano Márquez, Enrique; Jiménez Esteban, F. M.; Torres Gil, Santiago; Rodrigo Blanco, Carlos; Ferrer i Burjachs, Aina; Calcaferro, Leila M.; Althaus, Leandro G.; Córsico, Alejandro H. (Oxford University Press, 2021-10-01)
      Article
      Open Access
      We use the data provided by the Gaia Early Data Release 3 to search for a highly-complete volume-limited sample of unresolved binaries consisting of a white dwarf and a main sequence companion (i.e. WDMS binaries) within ...
