    • Lyman α wing absorption in cool white dwarf stars 

      Rohrmann, R. D.; Althaus, Leandro Gabriel; Kepler, Souza Oliveira (2011) [Artigo de periódico]
      Kowalski & Saumon identified the missing absorption mechanism in the observed spectra of cool white dwarf stars as the Lyman α red wing formed by the collisions between atomic and molecular hydrogen and successfully explained ...

    • New evolutionary sequences for hot h-deficient white dwarfs on the basis of a full account of progenitor evolution 

      Althaus, Leandro Gabriel; Panei, Jorge Alejandro; Bertolami, Marcelo Miguel Miller; García-Berro, Enrique; Córsico, Alejandro Hugo; Romero, Alejandra Daniela; Kepler, Souza Oliveira; Rohrmann, R. D. (2009) [Artigo de periódico]
      We present full evolutionary calculations appropriate for the study of hot hydrogen-deficient DO white dwarfs, PG 1159 stars, and DB white dwarfs. White dwarf sequences are computed for a wide range of stellar masses and ...
