Presentation Title: Relationship Between X-ray Luminosity and Magnetic Flux of Active Regions and X-ray Bright Points
Author(s): Kelvin Scheurer Dr. Keiji Yoshimura

Abstract:

Studying the relationship between magnetic fields and coronal emission is one way to approach the coronal heating problem. A clear power-law relationship between total unsigned magnetic flux and X-ray spectral luminosity over 12 orders of magnitude was reported in Pevtsov et al. (2003). In a recent study, Yoshimura et al. (2024) identified the cutoff magnetic field strength as a key parameter in influencing the power-law relationship. While Yoshimura et al. (2024) focused only on full sun data, we will expand the dataset to include XBPs and ARs. Utilizing data from Hinode/XRT and SDO/HMI, we successfully covered 5 orders of magnitude ranging between the lower XBP and upper AR. We will discuss the parameter dependency of the power-law relationship.
