Signatures of photospheric convection throughout the solar atmosphere: the EVE Sun-as-a-star mHz continuum
Hugh Hudson, Anne-Marie Broomhall, Lyndsay Fletcher +5
Convectively driven motions in the solar photosphere can generate broadband Doppler variability across the chromosphere, transition region and corona. Here we investigate this vari…
Diagnostics for the solar chromosphere using neutral carbon Rydberg lines
R. P. Dufresne, C. M. O. Osborne, G. Del Zanna
Diagnostics for the solar chromosphere are relatively few compared to other parts of the atmosphere. Despite this, hundreds of Rydberg lines emitted by neutrals in this region have…
Understanding Solar Flares and Energetic Events: Open questions, observational requirements, and instrumental needs over the coming decade
Malcolm K. Druett, Graham S. Kerr, Joel C. Allred +15
Solar flares are the largest energy-release events in the Solar System, allowing us to study fundamental physical phenomena under extreme conditions. Those include magnetic reconne…
Improving the atomic modelling for solar UV radiative transfer calculations
R. P. Dufresne, G. Del Zanna, C. M. J. Osborne
Radiative transfer calculations have been produced over the years for many lines and continua in the UV wavelength range of solar and cool stellar atmospheres for a variety of cond…
Observational signatures of mixing-induced cooling in the Kelvin-Helmholtz instability
Ben Snow, Chris Osborne, Andrew Hillier
Cool (K), dense material permeates the hot (K), tenuous solar corona in form of coronal condensations, for example prominences and coronal rain. As the…
Spectral Characteristics of a Rotating Solar Prominence in Multiple Wavelengths
A. G. M. Pietrow, V. Liakh, C. M. J. Osborne +2
We present synthetic spectra corresponding to a 2.5D magnetohydrodynamical simulation of a rotating prominence in the Ca II 8542 Ã , H, Ca II K, Mg II k, Ly , and Ly l…
