The Sun's Alfven Surface: Recent Insights and Prospects for the Polarimeter to Unify the Corona and Heliosphere (PUNCH)
Steven R. Cranmer, Rohit Chhiber, Chris R. Gilly +7
The solar wind is the extension of the Sun's hot and ionized corona, and it exists in a state of continuous expansion into interplanetary space. The radial distance at which the wi…
Formulating Mass-Loss Rates for Sun-like Stars: A Hybrid Model Approach
Munehito Shoda, Steven R. Cranmer, Shin Toriumi
We observe an enhanced stellar wind mass-loss rate from low-mass stars exhibiting higher X-ray flux. This trend, however, does not align with the Sun, where no evident correlation…
Estimates of Proton and Electron Heating Rates Extended to the Near-Sun Environment
R. Bandyopadhyay, C. M. Meyer, W. H. Matthaeus +11
A central problem of space plasma physics is how protons and electrons are heated in a turbulent, magnetized plasma. The differential heating of charged species due to dissipation…
Magnetohydrodynamic Mode Conversion in the Solar Corona: Insights from Fresnel-like Models of Waves at Sharp Interfaces
Steven R. Cranmer, Momchil E. Molnar
The solar atmosphere is known to contain many different types of wavelike oscillation. Waves and other fluctuations (e.g., turbulent eddies) are believed to be responsible for at l…
Constraining the systematics of (acoustic) wave heating estimates in the solar chromosphere
Momchil E. Molnar, Kevin P. Reardon, Steven R. Cranmer +2
Acoustic wave heating is believed to contribute significantly to the missing energy input required to maintain the solar chromosphere in its observed state. We studied the propagat…
