Electron Heat Flux in the Solar Wind: Generalized Approaches to Fluid Transport with a Variety of Skewed Velocity Distributions
Steven R. Cranmer, Avery J. Schiff
In the solar corona and solar wind, electron heat conduction is an important process that transports energy over large distances and helps determine the spatial variation of temper…
High-frequency wave power observed in the solar chromosphere with IBIS and ALMA
Momchil E. Molnar, Kevin P. Reardon, Steven R. Cranmer +3
We present observational constraints on the solar chromospheric heating contribution from acoustic waves with frequencies between 5 and 50 mHz. We utilize observations from the Dun…
Discovery of an Extremely Short Duration Flare from Proxima Centauri Using Millimeter through FUV Observations
Meredith A. MacGregor, Alycia J. Weinberger, R. O. Parke Loyd +17
We present the discovery of an extreme flaring event from Proxima Cen by ASKAP, ALMA, HST, TESS, and the du Pont Telescope that occurred on 2019 May 1. In the millimeter and FUV, t…
A Refined Model of Convectively-Driven Flicker in Kepler Light Curves
Samuel J. Van Kooten, Evan H. Anders, Steven R. Cranmer
Light curves produced by the Kepler mission demonstrate stochastic brightness fluctuations (or "flicker") of stellar origin which contribute to the noise floor, limiting the sensit…
Inward Propagating Plasma Parcels in the Solar Corona: Models with Aerodynamic Drag, Ablation, and Snowplow Accretion
Steven R. Cranmer, Craig E. DeForest, Sarah E. Gibson
Although the solar wind flows primarily outward from the Sun to interplanetary space, there are times when small-scale plasma inflows are observed. Inward-propagating density fluct…
An Updated Formalism For Line-Driven Radiative Acceleration and Implications for Stellar Mass Loss
Aylecia S. Lattimer, Steven R. Cranmer
Radiation contributes to the acceleration of large-scale flows in various astrophysical environments because of the strong opacity in spectral lines. Quantification of the associat…
Turbulent generation of magnetic switchbacks in the Alfvénic solar wind
Munehito Shoda, Benjamin D. G. Chandran, Steven R. Cranmer
One of the most important early results from the Parker Solar Probe (PSP) is the ubiquitous presence of magnetic switchbacks, whose origin is under debate. Using a three-dimensiona…
