Christopher; Kleinman, Scot James; Provencal, Judith L.; Mcgraw, J.T.; Birch, P.; Candy, M.; Buckley, David A.H.; Tripe, P.; Augusteijn, T.; Vauclair, Gérard; Kepler, Souza Oliveira; Kanaan Neto, Antonio Nemer (1993) [Artigo de periódico]
      New high-speed photometric observations ofthe pulsating DA white dwarfGD 165 are presented. The Fourier spectrum ofthe light curve ofGD 165 exhibits two main regions ofpower at 120 and 193 s. The presence of a high-amplitude ...

(2006) [Artigo de periódico]
      PG 0014+067 is one of the most promising pulsating subdwarf B stars for seismic analysis, as it has a rich pulsation spectrum. The richness of its pulsations, however, poses a fundamental challenge to understanding the ...
