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 کاملDetection of a classical δ Scuti star in the new eclipsing binary system HIP 7666
HIP 7666 is a variable star newly discovered during the Hipparcos mission and classified as of unknown type (ESA 1997). During 23 nights between July 2000 and November 2000, over 2300 CCD observations in the V band were obtained. These data show that the new variable is a detached eclipsing binary system with an orbital period of 2.37229 days. In addition, one of the components undergoes very s...
متن کاملThe first high-amplitude δ Scuti star in an eclipsing binary system
We report the discovery of the first high-amplitude δ Scuti star in an eclipsing binary, which we have designated UNSW-V-500. The system is an Algol-type semi-detached eclipsing binary of maximum brightness V = 12.52 mag. A best-fitting solution to the binary light curve and two radial velocity curves is derived using the Wilson–Devinney code. We identify a late-A spectral-type primary componen...
متن کاملSuperWASP discovery and SALT con rmation of a semi-detached eclipsing binary that contains a δ Scuti star
Aims. We searched the SuperWASP archive for objects that display multiply periodic photometric variations. Methods. Speci cally we sought evidence for eclipsing binary stars that display a further non-harmonically related signal in their power spectra. Results. The object 1SWASP J050634.16 353648.4 has been identi ed as a relatively bright (V ∼ 11.5) semi-detached eclipsing binary with a 5.104 ...
متن کاملIncidence of high-amplitude δ Scuti type variable stars
An order-of-magnitude estimate for the incidence of high-amplitude δ Scuti-type variable stars (HADS) in the δ Scuti area of the H-R diagram is calculated. Using a model for the stellar distribution in the Milky Way, we calculate the number of stars that are expected to fall in the δ Scuti area of the H-R diagram within the magnitude range and sky coverage of the ROTSE Survey for Variables I (R...
