On the irregular temporal behaviour of the variable star R Scuti
AB S TRACT We comment on the recent results of a temporal analysis of R Scuti, a star of RV Tauri type, presented by Buchler et al. As an alternative approach, we apply the technique of linear state space analysis to describe the irregular temporal behaviour with a linear stochastic process.We find evidence that the variability of R Scuti can be explained by the superposition of two stochastica...
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 کاملOn the Nature of Hd 207331: a New Δ Scuti Variable
While testing a Strömgren spectrophotometer attached to the 1.5-m telescope at the San Pedro Mártir observatory, Mexico, a number of A-type stars were observed, one of which, HD 207331, presented clear indications of photometric variability. CCD photometric data acquired soon after, confirmed its variability. In order to determine its pulsation behaviour more accurately, uvby differential photo...
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 کاملDiscrete Cosmological Self-Similarity and Delta Scuti Variable Stars
Within the context of a fractal paradigm that emphasizes nature’s well-stratified hierarchical organization, the δ Scuti class of variable stars is investigated for evidence of discrete cosmological self-similarity. Methods that were successfully applied to the RR Lyrae class of variable stars are used to identify Atomic Scale analogues of δ Scuti stars and their relevant range of energy levels...
