Photometric campaign on massive stars in the open cluster NGC 5617

TL;DR

This study conducted a photometric campaign on the open cluster NGC 5617 to analyze stellar pulsations, discovering new SPB candidates and providing insights into the internal structures of its stars.

Contribution

First detailed variability analysis of NGC 5617's stars, identifying new SPB candidates and enhancing understanding of stellar pulsations in this cluster.

Findings

Discovered several SPB star candidates.

Provided the first variability analysis of NGC 5617.

Enhanced knowledge of stellar internal structures.

Abstract

A campaign on the open cluster NGC 5617 was organized in order to characterize the pulsations and to better understand the internal structure of its stars. The variability of the cluster members was never studied before. We present the observations taken and an up-to-date analysis of the obtained time series, especially of several SPB candidates we discovered.
