Investigating the propagation of small-scale flare energy in the lower and upper atmosphere of solar active region
Girjesh Gupta, Ananya Rawat, Helen Mason +1
During solar flares, a considerable portion of the flare atmosphere becomes heated; however, the energy deposition process is still unclear, especially in the lower solar atmospher…
A benchmark study of atomic models for the transition region against quiet Sun observations
Roger Dufresne, Giulio Del Zanna, Helen Mason
The use of the coronal approximation to model line emission from the solar transition region has led to discrepancies with observations over many years, particularly for Li- and Na…
Analysis and modelling of recurrent solar flares observed with Hinode/EIS on March 9, 2012
V. Polito, G. Del Zanna, G. Valori +4
Three homologous C-class flares and one last M-class flare were observed by both the Solar Dynamics Observatory (SDO) and the Hinode EUV Imaging Spectrometer (EIS) in the AR 11429…
The CHIANTI atomic database
Peter R. Young, Ken P. Dere, Enrico Landi +2
The CHIANTI atomic database was first released in 1996 and has had a huge impact on the analysis and modeling of emissions from astrophysical plasmas. The database has continued to…
CHIANTI - An atomic database for Emission Lines. Version 8
G. Del Zanna, K. P. Dere, P. R. Young +2
We present version 8 of the CHIANTI database. This version includes a large amount of new data and ions, which represent a significant improvement in the soft X-ray, EUV and UV spe…
Solar Transition-Region Lines Observed by the Interface Region Imaging Spectrograph: Diagnostics for the O IV and Si IV Lines
Jaroslav Dudík, Giulio Del Zanna, Elena Dzifčáková +2
The formation of the transition-region O IV and Si IV lines observable by the Interface Region Imaging Spectrograph (IRIS) is investigated for both Maxwellian and non-Maxellian con…
On active region loops: Hinode/EIS observations
D. Tripathi, H. E. Mason, B. N. Dwivedi +2
Coronal loops are fundamental building blocks of the solar active regions and the corona. Therefore, a clear understanding of the physics of coronal loops will help us understand t…
EIT and TRACE responses to flare plasma
D. Tripathi, G. Del Zanna, H. E. Mason +1
Aims: To understand the contribution of active region and flare plasmas to the 195 channels of SOHO/EIT (Extreme-ultraviolet Imaging Telescope) and TRACE (Transition Region and…
EUV emission lines and diagnostics observed with Hinode/EIS
P. R. Young, G. Del Zanna, H. E. Mason +9
Quiet Sun and active region spectra from the Hinode/EIS instrument are presented, and the strongest lines from different temperature regions discussed. A list of emission lines rec…
Transition region features observed with Hinode/EIS
P. R. Young, G. Del Zanna, H. E. Mason +3
Two types of active region feature prominent at transition region temperatures are identified in Hinode/EIS data of AR 10938 taken on 2007 January 20. The footpoints of 1 MK TRACE…
