Observations of Ultrafast Kelvin Wave Breaking in the Mars Thermosphere
Edward M. B. Thiemann, Nicholas D. Entin, Stephen Bougher +3
Ultrafast Kelvin Waves (UFKWs) have been recently discovered at Mars using measurements by the Mars Atmosphere and Evolution (MAVEN) Accelerometer (ACC) instrument and the Mars Rec…
The effects of crustal magnetic fields and solar EUV flux on ionopause formation at Mars
F. Chu, Z. Girazian, D. A. Gurnett +5
We study the ionopause of Mars using a database of 6,893 ionopause detections obtained over 11 years by the MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) expe…
Solar flares observed by Rosetta at comet 67P
N. J. T. Edberg, F. L. Johansson, A. I. Eriksson +6
Context. The Rosetta spacecraft made continuous measurements of the coma of comet 67P/ Churyumov-Gerasimenko (67P) for more than two years. The plasma in the coma appeared very dyn…
Seasonal, Solar Zenith Angle, and Solar Flux Variations of O in the Topside Ionosphere of Mars
Zachary Girazian, Paul Mahaffy, Yuni Lee +1
Using observations from MAVEN's Neutral Gas and Ion Mass Spectrometer (NGIMS), we characterize the seasonal, solar zenith angle (SZA), and solar flux dependent variations of the O$…
Mars Thermospheric Variability Revealed by MAVEN EUVM Solar Occultations: Structure at Aphelion and Perihelion, and Response to EUV Forcing
E. M. B. Thiemann, F. G. Eparvier, S. W. Bougher +6
The Mars thermosphere holds clues to the evolution of the Martian climate, and has practical implications for spacecraft visiting Mars, which often use it for aerobraking upon arri…
Center-to-Limb Variability of Hot Coronal EUV Emissions During Solar Flares
Edward Thiemann, Phillip Chamberlin, Francis Eparvier +1
It is generally accepted that densities of quiet sun and active region plasma are sufficiently low to justify the optically thin approximation, and it is commonly used in the analy…
