Multi-wavelength synthesis of a flux rope-trapped mini-prominence eruption and post-flare coronal rain
Samrat Sen, Alexander G. M. Pietrow, Veronika Jer{\vc}i{ć} +1
Small-scale eruptive phenomena in the solar corona including miniature flux ropes and associated cool plasma condensations are not fully understood despite increasing high-resoluti…
A matter of class and flare Flare productivity in solar active regions and power-law constraints on the flare frequency distribution
A. G. M. Pietrow
Solar active regions are the source of virtually all significant space weather events, therefore the relationship between their observable properties and flare production is import…
The Fe I 4377 Ã Line as a Solar Faculae Indicator: Insights from Spectral Ratio Analysis
Katlyn L. Hobbs, Christopher A. Watson, Jean C. Costes +21
Faculae are a dominant source of stellar activity noise in radial velocity measurements, yet their low contrast and broad surface distribution make them difficult to track in disc-…
Multi-wavelength observations of substructures in solar flare ribbons
Vishal Singh, Eamon Scullion, Gert J. J. Botha +6
Solar flare ribbons are extensive brightenings in the chromosphere during flares, often showing fine scale structuring that reflects the underlying energy release. Using high caden…
Center-to-limb variations of solar active regions: Observations of spots, faculae, and network in the 6173 Ã continuum
A. G. M. Pietrow, S. Sumra, D. J. M. Petit dit de la Roche +3
Accurate modeling of stellar active regions (ARs) remains a major bottleneck for radial-velocity and transmission-spectroscopy studies aimed at finding Earth-like planets. While mu…
HelioSpectrotron 5000: An interactive multi-resolution solar spectral atlas
A. G. M. Pietrow
HelioSpectrotron 5000 (HS5000) is an interactive, multi-resolution solar spectral atlas designed to facilitate direct comparison between high-resolution reference spectra and obser…
