The 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 کاملAsteroseismology of δ Scuti stars in open clusters: Praesepe
The present paper provides a general overview of the asteroseismic potential of δ Scuti stars in clusters, in particular focusing on convection diagnostics. We give a summarise of the last results obtained by the authors for the Praesepe cluster of which five δ Scuti stars are analysed. In that work, linear analysis is confronted with observations, using refined descriptions for the effects of ...
متن کاملA seismological analysis of δ Scuti stars in the Pleiades cluster
A comparison between the oscillation frequencies of six multi-periodic δ Scuti stars of the Pleiades cluster and the eigenfrequencies of rotating stellar models that match the corresponding stellar parameters has been carried out. The assumption that all the stars considered have some common parameters, such as metallicity, distance or age, is imposed as a constraint. As a result, we have a bes...
متن کاملA Study of Convection with δ Scuti Stars in Open Clusters : the Pleiades
In this work we propose a preliminary seismic investigation of δ Scuti stars in the Pleiades cluster, focusing on potential diagnostics of convection and core-overshooting. Taking into account the effect of fast rotation in the modelling, we compare observed frequencies for 4 δ Scuti stars with radial linear instability predictions. A satisfying agreement is reached between the predicted ranges...
متن کاملPhotometric Study of Variable Stars in the Open Cluster NGC
We report the discovery of 19 variable stars and two blue–stragglers in the field of the open cluster NGC 6866. Three of the variable stars we classify as δ Sct, two, as γ Dor, four, as W UMa, two, as ellipsoidal variables, and one, as an eclipsing binary. Seven stars show irregular variability. Two of the pulsators, a δ Sct star NGC 6866-29 and a γ Dor star NGC 6866-21, are multiperiodic. From...
