      We observed G226-29 for 121 hr in 1992 February and confirm the presence of the three previously identified frequencies close to 109 s. We find no evidence of other pulsation periods down to our noise level of about 0.35 ...

    • Whole Earth Telescope observations of the helium interacting binary PG 1346+082 (CR bootis) 

      Provencal, Judith L.; Winget, Donald Earl; Nather, R. Edward; Robinson, E.L.; Clemens, J. Christopher; Bradley, Paul A.; Claver, C.F.; Kleinman, Scot James; Grauer, Albert D.; Hine, B.P.; Ferrario, Lilia; O'Donoghue, Darragh; Warner, B.; Vauclair, Gérard; Chevreton, Michel; Kepler, Souza Oliveira; Wood, Matthew A.; Henry, G.W. (1997) [Artigo de periódico]
      We present our analysis of 240 hr of white-light, high-speed photometry of the dwarf nova-like helium variable PG 1346+082 (CR Boo). We identify two frequencies in the low-state power spectrum, at 679.670±0.004 μHz and ...
