Characteristics of Jupiter's X‐Ray Auroral Hot Spot Emissions Using Chandra

To help understand and determine the driver of jovian auroral X-rays, we present first statistical study to focus on morphology dynamics northern hot spot (NHS) using Chandra data. The catalog explore dates from December 18, 2000 up including September 8, 2019. Using a numerical criterion, characterize typical extreme behavior concentrated NHS emissions across catalog. mean power is found be 1.91 GW with maximum brightness 2.02 Rayleighs (R), representing by far brightest parts X-ray spectrum. We report statistically significant region at center which always present, averaged nucleus (AHSNuc), 0.57 inferred average 1.2 R. use flux equivalence mapping model link this distinct output likely source location find that majority mappable photons emanate pre-dusk pre-midnight sector, coincident dusk flank boundary. A smaller cluster maps noon magnetopause boundary, dominated AHSNuc, suggesting there may multiple drivers emissions. On application timing analysis techniques (Rayleigh, Monte Carlo, Jackknife), identify several instances quasi-periodic oscillations (QPOs) in ranging 2.3 36.4 min, possible links ultra-low frequency activity boundary (e.g., dayside reconnection, Kelvin-Helmholtz instabilities).
