Multi-Height Spectropolarimetric Signatures of Magnetoacoustic Waves in Solar Plage
Taylor Sitterson, João M. da Silva Santos, Joshua Bentley +5
We analyze high-cadence spectropolarimetric observations of solar plage obtained with the Visible Spectro-Polarimeter (ViSP) on the Daniel K. Inouye Solar Telescope (DKIST) to inve…
Multi-wavelength synthesis of a flux rope-trapped mini-prominence eruption and post-flare coronal rain
Samrat Sen, Alexander G. M. Pietrow, Veronika Jercic +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 Å 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-…
From simulations to observations of cool plasma: What we can learn from synthetic spectra
V. Jerčić, T. A. Kucera, A. G. M. Pietrow +2
Cool plasma of coronal rain or prominences and filaments is ubiquitous in the solar corona. We explored the synthetic spectra of MgII h&k lines in detail and analyse how well a non…
Center-to-limb variations of solar active regions: Observations of spots, faculae, and network in the 6173 Å 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…
Fine-scale downflows above flare ribbons captured by Solar Orbiter/EUI
Zheng Sun, Alexander G. M. Pietrow, Malcolm K. Druett +8
In solar flares, flare ribbons map chromospheric footpoints where flare energy deposition occurs. These locations are associated with field aligned energy transport from the corona…
Transit timing and starspot-induced transit depth variations in the 17 Myr old HIP 67522 system
H. Chakraborty, M. Lendl, A. Nigioni +27
HIP 67522 is a one of the youngest multi-planetary systems discovered to date. The 17 Myr-old, Sun-like star is part of the Scorpius-Centarus OB association and is known to host tw…
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…
