Searching for solar-like oscillations in the δ Scuti star ρ Puppis
Despite the shallow convective envelopes of δ Scuti pulsators, solar-like oscillations are theoretically predicted to be excited in those stars as well. To search for such stochastic oscillations, we organized a spectroscopic multisite campaign for the bright, metal-rich δ Sct star ρ Puppis. We obtained a total of 2763 high-resolution spectra using four telescopes. We discuss the reduction and ...
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 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 ...
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 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 ...
