    • Evidence from K2 for Rapid Rotation in the Descendant of an Intermediate-mass Star 

      Hermes, James J.; Kawaler, Steven D.; Romero, Alejandra Daniela; Kepler, Souza Oliveira; Tremblay, Pier-Emmanuel; Bell, Keaton; Dunlap, Bart; Montgomery, Michael Houston; Gänsicke, Boris; Clemens, J. Christopher; Dennihy, Erik D.; Redfield, Seth (2017) [Artigo de periódico]
      Using patterns in the oscillation frequencies of a white dwarf observed by K2, we have measured the fastest rotation rate (1.13 ± 0.02 hr) of any isolated pulsating white dwarf known to date. Balmer-line fits to follow-up ...

    • Gaia white dwarfs within 40 pc : I. Spectroscopic observations of new candidates 

      Tremblay, Pier-Emmanuel; Kepler, Souza Oliveira; Torres, Sergio (2020) [Artigo de periódico]
      We present a spectroscopic survey of 230 white dwarf candidates within 40 pc of the Sun from the William Herschel Telescope and Gran Telescopio Canarias. All candidates were selected from Gaia Data Release 2 (DR2) and in ...
