Magnetism and the Invisible Man: The mysteries of coronal cavities
Sarah Gibson
Magnetism defines the complex and dynamic solar corona. Twists and tangles in coronal magnetic fields build up energy and ultimately erupt, hurling plasma into interplanetary space…
Type III Solar Radio Burst Source Region Splitting Due to a Quasi-Separatrix Layer
Patrick I. McCauley, Iver H. Cairns, John Morgan +4
We present low-frequency (80-240 MHz) radio imaging of type III solar radio bursts observed by the Murchison Widefield Array (MWA) on 2015/09/21. The source region for each burst s…
Origins of the Ambient Solar Wind: Implications for Space Weather
Steven R. Cranmer, Sarah E. Gibson, Pete Riley
The Sun's outer atmosphere is heated to temperatures of millions of degrees, and solar plasma flows out into interplanetary space at supersonic speeds. This paper reviews our curre…
Magnetic nulls and super-radial expansion in the solar corona
Sarah E. Gibson, Kevin Dalmasse, Laurel A. Rachmeler +5
Magnetic fields in the sun's outer atmosphere -- the corona -- control both solar-wind acceleration and the dynamics of solar eruptions. We present the first clear observational ev…
Coronal cavities: observations and implications for the magnetic environment of prominences
Sarah E. Gibson
Dark and elliptical, coronal cavities yield important clues to the magnetic structures that cradle prominences, and to the forces that ultimately lead to their eruption. We review…
