Variable stars in the field of open cluster NGC 1039

RGR.A. GAYSIN RKR. G. Karimov SEShuhrat Ehgamberdiev

Key Points

Fourteen variable star candidates were identified in the field of NGC 1039, suggesting significant variability in stellar populations.
The analysis utilizes TESS mission light curves to assess and understand variable stars within the open cluster.
Incorporating data from Gaia DR3, probable membership and fundamental parameters of NGC 1039 were determined.
Understanding variable stars within open clusters may enhance knowledge of stellar formation and evolution.

Abstract

Here we present preliminary results from the search and study of variable stars based on space-based observation data from the TESS mission, focusing on the field of the open star cluster NGC 1039. The light curves of various types of variable stars located within the cluster field are analyzed. Using data from the Gaia DR3 release, we determined the probable members and fundamental parameters of the cluster, as well as assessed the likely membership of the identified 14 variable star candidates in the field NGC1039.
