The observational evidence that all microflares that accelerate electrons to high energies are rooted in sunspots
Andrea Francesco Battaglia, Säm Krucker, Astrid M. Veronig +6
In general, large solar flares are more efficient at accelerating high-energy electrons than microflares. Nonetheless, we sometimes observe microflares that accelerate electrons to…

A comparative study of two X2.2 and X9.3 solar flares observed with HARPS-N: Reconciling Sun-as-a-star spectroscopy and high-spatial resolution solar observations in the context of the solar-stellar connection
A. G. M. Pietrow, M. Cretignier, M. K. Druett +14
Stellar flares cannot be spatially resolved, which complicates ascertaining the physical processes behind particular spectral signatures. Due to their proximity to Earth, solar fla…
