    • 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 ...

      Rosa, Gabriela Oliveira da; Kepler, Souza Oliveira; Córsico, Alejandro Hugo; Costa, Jose Eduardo da Silveira; Hermes, James J.; Kawaler, Steven D.; Bell, Keaton; Montgomery, Michael Houston; Provencal, Judith L.; Winget, Donald Earl; Handler, Gerald; Dunlap, Bart; Clemens, J. Christopher; Uzundag, Murat (2022) [Artigo de periódico]
      PG 1159-035 is the prototype of the PG 1159 hot (pre-)white dwarf pulsators. This important object was observed during the Kepler satellite K2 mission for 69 days in 59 s cadence mode and by the TESS satellite for 25 days ...
