    • The rapidly pulsating subdwarf B star PG 1325+101 I. Oscillation modes from multisite observations 

      Silvotti, R.; Bonanno, Alfio M.; Bernabei, Stefano; Fontaine, G.; Charpinet, Stéphane; Leccia, Silvio; Kjeldsen, Hans; Oswalt, T. D.; Rudkin, Mark J.; Johnston, Kyle B. (2006-11)
      In this article we present the results of 215 h of time-series photometry on the rapidly pulsating subdwarf B star PG 1325+101 (Teff - 35 000 K, log g = 5.8, log N(Hs)/N(H) = -1.7), obtained during 25 days of observation ...
    • The rapidly pulsating subdwarf B star PG 1325+101 II. Structural parameters from asteroseismology 

      Charpinet, Stéphane; Silvotti, R.; Bonanno, Alfio M.; Fontaine, G.; Brassard, Pierre; Chayer, Pierre; Green, Elizabeth M.; Oswalt, T. D.; Rudkin, Mark J.; Johnston, Kyle B. (2006-11)
      We present a detailed analysis of the rapidly pulsating subdwarf B star (or EC14026 star) PG 1325+101. This analysis exploits the outcome of dedicated multisite observations using time-series photometry that revealed the ...
    • The temporal spectrum of the sdB pulsating star HS 2201+2610 at 2 ms resolution 

      Silvotti, R.; Janulis, Rimvydas; Schüh, Sonja L.; Charpinet, Stéphane; Oswalt, T. D.; Silvestri, Nicole M.; González-Pérez, J. M.; Kalytis, Romualdas; Meištas, E. G.; Carlson, Glenn (2002-07)
      In this article we present the results of more than 180 hours of time-series photometry on the low gravity (log g = 5.4, Teff = 29 300 K, log He/H = -3.0 by number) sdB pulsating star HS 2201+2610, obtained between September ...
