On 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 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 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...
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...
