Astronomy and Astrophysics the Δ Scuti Star Fg Vir. Iv. Mode Identifications and Pulsation Modelling
This paper examines the mode identification and presents pulsation models for FG Vir, for which 24 frequencies have been detected. Histograms of the frequency spacings show peaks which are identified with adjacent radial orders and rotational splitting. Pulsational l values are deduced for eight modes by comparing the observed photometric phase lags between v and y variations with calculated va...
متن کاملComplicated pulsation in the δ Scuti variable 59 Aurigae
Eight-night photoelectric photometric observations through v and y bands confirm the complicated pulsation of δ Scuti variable 59 Aurigae. Power spectra of light curves show multi-period pulsation behavior, and eight pulsation frequencies f1=6.8283, f2=6.3179, f3=5.0074, f4=5.9535, f5=4.3285, f6=5.6854, f7=9.0206 and f8=8.6260 cycles per day are identified. After subtraction of the best eight f...
متن کاملWASP-33: the first δ Scuti exoplanet host star⋆
We report the discovery of photometric oscillations in the host star of the exoplanet WASP-33 b (HD 15082). The data were obtained in the R band in both transit and out-of-transit phases from the 0.3-m telescope and the Montcabrer Observatory and the 0.8-m telescope at the Montsec Astronomical Observatory. Proper fitting and subsequent removal of the transit signal reveals stellar photometric v...
متن کاملPhotometric Modal Discrimination in Δ Scuti and Γ Doradus Stars
Abstract. The potential of photometric methods for the identification of l, the degree of spherical surface harmonic of a pulsating star, is investigated with special emphasis on Strömgren photometry applied to δ Scuti and γ Dor variables. Limitations of actual model atmospheres when fine precision is required for the calculations of partial derivatives and integrals, which depend on limb darke...
متن کاملPeriod change and δ Scuti pulsations of eclipsing binary star RZ Cassiopiae
RZ Cas is an Algol-type partial eclipsing binary, the secondary component of which has filled its Roche lobe. Its visual magnitude is 6.18 and its period is 1.195 days. The most important characteristics of RZ Cas are period change (due to mass transfer) and anomalies in the primary minimum of its light curve (due to δ Scuti pulsations). In this paper, light curves of RZ Cas are obtained using ...
