Contribution

It provides an extensive dataset and initial analysis of oscillating stars in NGC 884, advancing understanding of massive star pulsations.

Findings

Identification of several interesting oscillating stars

Large dataset of nearly 78,000 CCD frames

Current status and future plans for data analysis

Abstract

To improve our comprehension of the beta Cephei stars, we set up a photometric multi-site campaign on the open cluster NGC 884 (Chi Persei). Thirteen telescopes joined the 2005-2007 campaign which resulted in almost 78000 CCD frames. We present an up-to-date status of the analysis of these data, in which several interesting oscillating stars are pointed out. We end with the future prospects.
