Period 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 ...
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 کاملOn the nature of the δ Scuti star star HD 115520
As a continuation of the study of the newly found δ Scuti star HD 115520, we present a period analysis of recently acquired photometric data covering four nights, as well as some conclusions on the nature of this star.
متن کاملAstronomy 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 کاملThe δ Scuti star θ Tucanae ? II . uvby colour variations and pulsational / orbital properties
On the basis of almost 1500 uvby photometric observations of θ Tucanae collected in 1993, we discuss the colour variation of this multi-periodic δ Scuti star and debate some of its binary and pulsational properties. The frequencies f1 = 0.281 and f2 = 0.142 cd−1 embody orbital motion in a 7. d04 day ellipsoidal configuration characterised by a light curve with unequal maxima and minima and a co...
