Astronomical Seal notes activity from GK Betelgeuse
The Abu Dhabi Astronomical Observatory has observed unprecedented activity from the star "GK Persei," where changes in its brightness were measured during the monitoring period, along with periodic fluctuations in luminosity that reflect developments within its stellar system. This star is classified as a variable double star and has a historical significance dating back to a major explosion in 1901. It is currently considered a magnetic variable system composed of a white dwarf that accretes material from a companion star, characterized by a high rotational speed and short periodicities. These observations contribute to our understanding of the physical processes involved. This monitoring is part of a global campaign to explore the nature of the system and is among the most significant scientific observations tracking stellar activity over more than 125 years.
