O VI and H_2 Lines in Sunspots
Nicolas Labrosse, Huw Morgan, Shadia Rifai Habbal +1
Sunspots are locations on the Sun where unique atmospheric conditions prevail. In particular, the very low temperatures found above sunspots allow the emission of H_2 lines. In thi…
An Empirical 3D Model of the Large-scale Coronal Structure Based on the Distribution of Prominences on the Solar Disk
Huw Morgan, S. Rifai Habbal
Despite the wealth of solar data currently available, the explicit connection between coronal streamers and features on the solar disk remains unresolved. An empirical three-dimens…
The Impact of Sunspots on the Interpretation of Coronal Observations of the O VI Doublet
H. Morgan, Shadia Rifai Habbal
Due to their high intensity of emission in the O VI 1031.9 and 1037.6A lines, even small sunspots on the solar disk can strongly influence the intensity of the radiative scattering…
The Depiction of Coronal Structure in White Light Images
Huw Morgan, Shadia Rifai Habbal, Richard Woo
The very sharp decrease of density with heliocentric distance makes imaging of coronal density structures out to a few solar radii challenging. The radial gradient in brightness ca…
Are Neutral Sunspot Winds Important for Penumbral Dynamics and the First Ionization Potential Effect?
J. R. Kuhn, H. Lin, H. Morgan
The low ionization state in parts of a sunspot may play an important role in its evolution and dynamical state. The cool magnetic interior region of the sunspot develops a substant…
