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…
