Multi-spacecraft Measurements of the Evolving Geometry of the Solar Alfvén Surface Over Half a Solar Cycle
Samuel T. Badman, Michael L. Stevens, Stuart D. Bale +18
The geometry of a star's Alfvén surface determines stellar angular momentum loss, separates a causally distinct 'corona' and stellar wind, and potentially affects exoplanetary hab…

A parametric study of solar wind properties and composition using fluid and kinetic solar wind models
Paul Lomazzi, Alexis P. Rouillard, Michael A. Lavarra +7
The physical processes in the solar corona that shape the solar wind remain an active research topic. Modeling efforts have shown that energy and plasma exchanges near the transiti…

Differentiating the acceleration mechanisms in the slow and Alfvénic slow solar wind
Yeimy J. Rivera, Samuel T. Badman, J. L. Verniero +18
In the corona, plasma is accelerated to hundreds of kilometers per second, and heated to temperatures hundreds of times hotter than the Sun's surface, before it escapes to form the…
