RX J2117.1+3412 (V2027 Cyg) light curves

DOI

We report the effort to search for white dwarf p-mode oscillations in RX J2117.1+3412 (V2027 Cyg), a GW Vir star. The data were taken with Miosotys, a multi-fiber photometer, mounted on the 1.93-m telescope at Observatoire de Haute-Provence (OHP) with a 20-Hz cadence in May 2010 and June 2012. Two intriguing signatures at 1.2081Hz and 2.5852Hz were found at 3.8{sigma} and 3.5{sigma} significance levels, respectively. However, possible atmospheric effects cannot be ruled out. If these two features are not real, the 3{sigma} upper limit of the relative amplitude for the possible oscillations in the frequency range from 1 to 10Hz is estimated to be about 6x10^-4^. This is the first report in the literature for a p-mode oscillation search of GW Vir stars.
