Time-series Photometry and Analysis of the BY Draconis Class Star: GSC 05586-00270

This study investigates GSC 05586-00270 (a BY Draconis star) through data obtained from the ASAS-SN survey and additional observations from several observatories in Malta and another at La Palma (Spain). The study reveals the star's multi-period variability, with a primary period of 9.098805+-0.001507 days. Our analysis demonstrates that the primary period is relatively stable. Data analysis also divulged occasional fading and systematic variations in brightness and colour as the star undergoes rotation coupled with phenomena emanating from magnetic activity. A long-term period of approximately 4442 days was also identified, suggesting potential star spot migration influenced by other external factors. As opposed to some BY Draconis stars that are single, our analysis indicates that GSC 05586-00270 is likely to be a binary star system, influencing further the star's brightness variations. These findings shed light on the dynamic nature of this star and highlight the need for more comprehensive research to understand its behaviour further.
