Abstract:
KUV 05134+2605 is one of the 21 pulsating DB white dwarfs (V777 Her or
DBV variables) known so far. The detailed investigation of the
short-period and low-amplitude pulsations of these relatively faint
targets requires considerable observational efforts from the ground,
long-term single-site or multi-site observations. The observed
amplitudes of excited modes undergo short-term variations in many
cases, which makes determining pulsation modes difficult.
We aim to determine the pulsation frequencies of KUV 05134+2605, find
regularities between the frequency and period components, and perform
an asteroseismic investigation for the first time.
Description:
Observations of KUV 05134+2605 were obtained on 11 nights in the
2007/2008 observing season and on 3 nights in 2011 with the 1m
Ritchey-Chretien-Coude telescope at Piszkesteto mountain station of
Konkoly Observatory. The measurements were made with a Princeton
Instruments VersArray:1300B back-illuminated CCD camera in white light
and with 30s integration times.
