A universal scaling between damping time and period of quasi-periodic pulsations from solar EUV brightenings to X-ray stellar flares

Daye Lim, Tom Van Doorsselaere, Valery M. Nakariakov +5

Recent high spatial and temporal resolution extreme-ultraviolet (EUV) imaging observations have revealed that quasi-periodic pulsations (QPPs), a ubiquitous signature of impulsive…

Accessing the fine temporal scale of EUV brightenings and their quasi-periodic pulsations: 1 second cadence observations by Solar Orbiter/EUI

Daye Lim, Tom Van Doorsselaere, Nancy Narang +7

Small scale extreme ultraviolet (EUV) transient brightenings are observationally abundant and critically important to investigate. Determining whether they share the same physical…

28 Years of Sun-as-a-star Extreme Ultraviolet Light Curves from SOHO EIT

Emily Sandford, Frédéric Auchère, Annelies Mortier +2

The Solar and Heliospheric Observatory (SOHO) Extreme-ultraviolet Imaging Telescope (EIT) has been taking images of the Solar disk and corona in four narrow EUV bandpasses (171Ã ,…

Quasi-periodic pulsations in extreme-ultraviolet brightenings

Daye Lim, Tom Van Doorsselaere, David Berghmans +5

Context. Extreme-ultraviolet (EUV) observations have revealed small-scale transient brightenings that may share common physical mechanisms with larger-scale solar flares. A notable…

Spatial distributions of EUV brightenings in the quiet-Sun

C. J. Nelson, L. A. Hayes, D. Müller +16

The identification of large numbers of localised transient EUV brightenings, with small spatial scales, in the quiet-Sun corona has been one of the key early results from Solar Orb…
