Growing evidence suggests that extragalactic fast X-ray transients discovered by the Einstein Probe (EP-EFXTs) share observational properties with gamma-ray bursts (GRBs). Long GRBs (lGRBs) are traditionally associated with the core collapse of massive stars and are expected to trace the cosmic star formation rate (SFR...
The advent of large-scale time-domain surveys provides both opportunities and challenges for understanding accretion disk evolution in cataclysmic variables (CVs). Using high-cadence photometry from the Transiting Exoplanet Survey Satellite (TESS), we investigate the eclipsing SU UMa-type dwarf nova Z Cha. Leveraging e...

Stellar flares are one of the most prominent phenomena on the surface of stars, and they can have a profound impact on the space environment, constrain the stellar magnetic evolution theory, and support livable exoplanet surveys. Limited by observations, previous research was aimed at individual flaring stars, especial...
