Wandering near the red edge: photometric observations of three cool ZZ Ceti stars
Zs. Bognár, M. Paparó, Á. Sódor +11
We summarize our findings on three cool ZZ Ceti type pulsating white dwarfs. We determined eight independent modes in HS 0733+4119, of which seven are new findings. For GD 154, we…
Amplitude Modulation in the ZZ Ceti Star GD 244
Zs. Bognár, M. Paparó, L. Molnár +2
Previous studies of GD 244 revealed seven pulsation frequencies (two doublets and three single periods) in the light variations of the star. The data obtained at McDonald Observato…
GD 244: asteroseismology of a pulsator in the middle of the ZZ Ceti instability strip
Zs. Bognár, M. Paparó
We present our preliminary results on the asteroseismological investigations of the ZZ Ceti star GD 244. We used literature values of the effective temperature and surface gravity…
More frequencies of KUV 02464+3239
Zs. Bognár, M. Paparó, A. Már +6
Preliminary results on KUV 02464+3239, a pulsating DA white dwarf are presented. Located near the red edge of the DAV instability strip, KUV 02464+3239 shows large amplitude and lo…
GD 99 - an unusual, rarely observed DAV white dwarf
Zs. Bognár, M. Paparó, B. Steininger +1
New observations of GD 99 are analysed. The unusual pulsation behaviour, showing both long and short periods, has been confirmed. All the available periods show a grouping of short…
