Detection of stellar-like abundance anomalies in the slow solar wind
David H. Brooks, Deborah Baker, Lidia van Driel-Gesztelyi +2
The elemental composition of the Sun's hot atmosphere, the corona, shows a distinctive pattern that is different than the underlying surface, or photosphere (Pottasch 1963). Elemen…
Active region contributions to the solar wind over multiple solar cycles
D. Stansby, L. M. Green, L. van Driel-Gesztelyi +1
Both coronal holes and active regions are source regions of the solar wind. The distribution of these coronal structures across both space and time is well known, but it is unclear…
The Evolution of Plasma Composition During a Solar Flare
Andy S. H. To, David M. Long, Deborah Baker +4
We analyse the coronal elemental abundances during a small flare using Hinode/EIS observations. Compared to the pre-flare elemental abundances, we observed a strong increase in cor…
Alfvenic Perturbations in a Sunspot Chromosphere Linked to Fractionated Plasma in the Corona
D. Baker, M. Stangalini, G. Valori +7
In this study, we investigate the spatial distribution of highly varying plasma composition around one of the largest sunspots of solar cycle 24. Observations of the photosphere, c…
Dynamics of Late-Stage Reconnection in the 2017 September 10 Solar Flare
Ryan J. French, Sarah A. Matthews, Lidia van Driel-Gesztelyi +2
In this multi-instrument paper, we search for evidence of sustained magnetic reconnection far beyond the impulsive phase of the X8.2-class solar flare on 2017 September 10. Using H…
Flaring activity of Proxima Centauri from TESS observations: quasi-periodic oscillations during flare decay and inferences on the habitability of Proxima b
Krisztián Vida, Katalin Oláh, Zsolt Kővári +3
We analyze the light curve of the M5.5 dwarf Proxima Centauri obtained by the TESS in Sectors 11 and 12. In the day-long light curve we identified and analyzed 72 flar…
Modelling the Effect of Mass-Draining on Prominence Eruptions
Jack M. Jenkins, Matthew Hopwood, Pascal Démoulin +4
Quiescent solar prominences are observed to exist within the solar atmosphere for up to several solar rotations. Their eruption is commonly preceded by a slow increase in height th…
The quest for stellar coronal mass ejections in late-type stars: I. Investigating Balmer-line asymmetries of single stars in Virtual Observatory data
Krisztián Vida, Martin Leitzinger, Levente Kriskovics +5
Flares and CMEs can have deleterious effects on their surroundings: they can erode atmospheres of orbiting planets over time and also have high importance in stellar evolution. Mos…
A Solar cycle correlation of coronal element abundances in Sun-as-a-star observations
David H. Brooks, Deborah Baker, Lidia van Driel-Gesztelyi +1
The elemental composition in the coronae of low-activity solar-like stars appears to be related to fundamental stellar properties such as rotation, surface gravity, and spectral ty…
Mass estimates of rapidly-moving prominence material from high-cadence EUV images
David R Williams, Deborah Baker, Lidia van Driel-Gesztelyi
We present a new method for determining the column density of erupting filament material using state-of-the-art multi-wavelength imaging data. Much of the prior work on filament/pr…
Eruption of a Kink-Unstable Filament in Active Region NOAA 10696
D. R. Williams, T. Toeroek, P. Demoulin +2
We present rapid-cadence Transition Region And Coronal Explorer (TRACE) observations which show evidence of a filament eruption from active region NOAA 10696, accompanied by an X2.…
