    • Catalog of magnetic white dwarfs with hydrogen dominated atmospheres 

      Amorim, Larissa Luciano; Kepler, Souza Oliveira; Kulebi, Baybars; Jordan, Stefan; Romero, Alejandra Daniela (2023) [Artículo de periódico]
      White dwarfs are excellent research laboratories as they reach temperatures, pressures, and magnetic fields that are unattainable on Earth. To better understand how these three physical parameters interact with each other ...

    • Magnetic white dwarf stars in the Sloan Digital Sky Survey 

      Kepler, Souza Oliveira; Pelisoli, Ingrid Domingos; Jordan, Stefan; Kleinman, Scot James; Koester, Detlev; Kulebi, Baybars; Antonio, Viviane Peçanha; Castanheira, Bárbara Garcia; Nitta, Atsuko; Costa, Jose Eduardo da Silveira; Winget, Donald Earl; Kanaan Neto, Antonio Nemer; Fraga, Luciano (2013) [Artículo de periódico]
      To obtain better statistics on the occurrence of magnetism among white dwarfs, we searched the spectra of the hydrogen atmosphere white dwarf stars (DAs) in the Data Release 7 of the Sloan Digital Sky Survey (SDSS) for ...

    • New white dwarf stars in the Sloan Digital Sky Survey Data Release 10 

      Kepler, Souza Oliveira; Pelisoli, Ingrid Domingos; Koester, Detlev; Ourique, Gustavo; Kleinman, Scot James; Romero, Alejandra Daniela; Nitta, Atsuko; Eisenstein, Daniel, J.; Costa, Jose Eduardo da Silveira; Kulebi, Baybars; Jordan, Stefan; Dufour, Patrick; Giommi, Paolo; Rebassa-Mansergas, Alberto (2015) [Artículo de periódico]
      We report the discovery of 9088 new spectroscopically confirmed white dwarfs and subdwarfs in the Sloan Digital Sky Survey Data Release 10. We obtain Teff, log g and mass for hydrogen atmosphere white dwarf stars (DAs) and ...
