Oscillation Frequencies of Moderately Rotating Delta Scuti Stars: Asymmetric Mode Splittings Due to Non-spherical Distortion
Zhao Guo, Timothy R. Bedding, A. A. Pamyatnykh +5
We find that the observed pressure-mode rotational splittings of slowly/moderately rotating Delta Scuti stars and Beta Cephei stars mostly have a positive asymmetry. That is, the l…
A need to revise stellar opacities from asteroseismology of Scuti stars
Jadwiga Daszyńska-Daszkiewicz, Przemysław Walczak, Alexey Pamyatnykh +2
We construct seismic models of the four double-mode radial Scuti stars adopting opacities from three databases: OPAL, OP and OPLIB. The aim is to find the models that fit the o…
Asteroseismology of the double-radial mode Scuti star BP Pegasi
Jadwiga Daszyńska-Daszkiewicz, P. Walczak, A. A. Pamyatnykh +1
Using the ASAS data, we determine the pulsational frequencies of the high-amplitude Sct star BP Pegasi. The analysis revealed only the two known, independent frequencies. On th…
Mode identification and seismic study of Scuti, the prototype of a class of pulsating stars
Jadwiga Daszynska-Daszkiewicz, A. A. Pamyatnykh, P. Walczak +3
We present a seismic study of Scuti based on a mode identification from multicoulor photometry. The dominant frequency can be associated only with a radial mode and the second…
Seismic analysis of the double-mode radial pulsator SX Phoenicis
Jadwiga Daszyńska-Daszkiewicz, A. A. Pamyatnykh, P. Walczak +1
We present the results of complex seismic analysis of the prototype star SX Phoenicis. This analysis consists of a simultaneous fitting of the two radial-mode frequencies, the corr…
Complex asteroseismology of SX Phoenicis
J. Daszyńska-Daszkiewicz, P. Walczak, A. Pamyatnykh +2
We present seismic analysis of the prototype SX Phoenicis that aims at fitting the two radial-mode frequencies and the corresponding values of the bolometric flux amplitude (the pa…
