03/11 3pm-4pm: Daye Lim (Exeter): "From EUV Brightenings to Stellar Flares: Universal Scaling of Quasi-Periodic Pulsations"

When: 3pm - 4pm, Tue, 03 Nov '26

Where: F25A (Millburn)

Small-scale extreme-ultraviolet (EUV) brightenings are ubiquitous in the solar corona and may represent the low-energy counterparts of larger solar flares, with important implications for coronal heating. A key observational signature of solar and stellar flares is the presence of quasi-periodic pulsations (QPPs), which are thought to reflect fundamental processes of impulsive energy release. QPPs can therefore provide a useful diagnostic for determining whether EUV brightenings share the same underlying mechanisms as larger-scale flares or instead represent a fundamentally distinct regime.

In this talk, I will present observations from the high spatial and temporal resolution of the Solar Orbiter/Extreme Ultraviolet Imager, showing clear evidence that QPPs are present in EUV brightenings. I will characterise their properties over a wide range of spatial and temporal scales and show that their periods extend from a few seconds to several minutes, comparable to those observed in larger flares. I will also discuss the relationship between QPP damping time and period, which follows a common power-law scaling for both EUV brightenings and EUV solar flares. When combined with previously reported X-ray QPPs from solar and stellar flares, these events align with a single scaling trend spanning many orders of magnitude in scale. This apparent universality suggests that QPPs in small-scale brightenings, solar flares, and stellar flares may be governed by a broadly common underlying physical mechanism.
