Study of the open cluster Alessi-Teutsch 9 (ASCC 10) using multiband photometry and Gaia EDR3

Néstor Sánchez, F. López-Martínez, Sandra Ocando, Pere Blay

There is a growing interest in the automated characterization of open clusters using data from the Gaia mission. This work evidences the importance of choosing an appropriate sampling radius (the radius of the circular region around the cluster used to extract the …

Pulsation and rotation in NGC 6811: the Kepler short-cadence stars

Eloy Rodríguez, L. A. Balona, M. J. López‐González, Sandra Ocando et autres

ABSTRACT We have analysed a selected sample of 36 Kepler short-cadence stars in the field of NGC 6811. The results reveal that all the targets are variable: two red giant stars with solar-like oscillations, 21 main-sequence pulsators (16 δ Scuti and five …
