Contribution

It offers new long-term multicolor photometric observations of PMS stars in the 'Gulf of Mexico' region, enhancing understanding of their variability and classification.

Findings

Stars exhibit different types of photometric variability.

Data aids in more accurate classification of PMS stars.

Long-term observations are essential for understanding stellar evolution.

Abstract

We present new data from BVRI photometric observations of five PMS stars during the period from April 2013 to July 2014. The stars are located in the field of NGC 7000/IC 5070 ("Gulf of Mexico") - a region with active star formation. The presented paper is a continuation of our long-term photometric investigations of the young stellar objects in this region. The long-term multicolor photometric observations of PMS stars are very important for their exact classification. Our results show that the studied stars exhibit different types of photometric variability in all bands. We tried to classify them using our data from the long-term photometry and data published by other authors.
