Astronomical Center Detects Activity in GK Betelgeuse
The study focused on monitoring the stellar activity of the "GK Berchous" variable star at the Emirates Astronomical Observatory. Measurements revealed fluctuations in its brightness throughout 2026, with a gradual decrease in luminosity and variations in brightness caused by changes in mass transfer within the binary star system. The star is considered an important object for studying variable stars, characterized by a high rotation speed (approximately 351 seconds) and an orbital period of about two days. Notable changes in brightness are linked to the accumulation of matter around the white dwarf. The study confirmed that activity monitoring increases when recent data from space telescopes are available, and the presence of a molecular hydrogen envelope surrounding the system provides new insights into the interaction between matter and the surrounding environment. This enhances understanding of the evolution of the supernova remnant since its explosion in 1901.
