Unveiling U Gem Outbursts: Light Curve Analysis and Exploring Correlations of Outburst Mechanism

open access: yes
As a nova-typed cataclysmic star, U Gem exhibits outbursts in brightness and stars like this have left astronomers puzzled about the underlying mechanism. By analyzing U Gem’s light curve (a graph representing its changing magnitude over time which reveals the outburst cycle), spectrums, and the temperature variation of its white dwarf component, we ...
