Contribution
The paper introduces new variable stars in M79 and refines its Oosterhoff classification using advanced photometric analysis.
Findings
Six new variable stars discovered in M79
M79 classified as Oosterhoff type II
Enhanced understanding of stellar variability in M79
Abstract
We present preliminary results obtained from analysis of the VI photometry of the globular cluster M79. Stellar variability survey performed with the image subtraction method yielded six new pulsating stars: two of RR Lyrae type, three SX Phoenicis stars and even one W Virginis star. Using all eleven RR Lyrae stars known in the cluster we find that M79 is Oosterhoff type II globular cluster.
