Doppler Dimming and Brightening Effects in Solar Prominences
Aaron W. Peat, Christopher M. J. Osborne, Petr Heinzel
We explored the impact that Doppler dimming and brightening effects from bulk motions of solar prominences have on the formation of Lya, Ha, and MgII h line profiles. We compared t…

The Bright Rim Prominences according to 2.5D Radiative Transfer
Jack M. Jenkins, Christopher M. J. Osborne, Ye Qiu +2
Solar prominences observed close to the limb commonly include a bright feature that, from the perspective of the observer, runs along the interface between itself and the underlyin…
