Hipparcos parallaxes and the nature of δ Scuti stars ?
Hipparcos parallaxes give new tests of the nature of δ Sct variables. For many individual stars accurate distances are now available, i.e. directly determined luminosities and radii can be used to test theoretical models. Of particular interest are the at present very unclear relations between high–amplitude δ Sct stars and the much more abundant low–amplitude δ Sct variables, and the relations...
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 کاملThe search for δ Scuti stars in open clusters
In order to improve the tests of models of stellar evolution, observations giving tighter constraints on the models were initiated by the formation of an informal group STACC (Frandsen, 1992). The purpose of the group is to search for and make observations of δ Scuti stars in open clusters. This paper presents some of the results of the search, mainly for distant open clusters with a rich popul...
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...
متن کاملPeriod changes of δ Scuti stars and stellar evolution
Period changes of δ Scuti stars have been collected or redetermined from the available observations and are compared with values computed from evolutionary models with and without convective core overshooting. For the radial pulsators of Pop. I, the observations indicate (1/P) dP/dt values around 10 year with equal distribution between period increases and decreases. The evolutionary models, on...
