The role of the electron temperature on ion loss from Mars

Autor: Stephen A. Ledvina, Bruce M. Jakosky, Stephen H. Brecht

Publikováno v: Journal of Geophysical Research: Space Physics. 122:8375-8390

This paper reports the results of hybrid simulations of the Mars-solar wind interaction. The focus is on the role of the low altitude (

Ion escape rates from Mars: Results from hybrid simulations compared to MAVEN observations

Autor: David Brain, Stephen H. Brecht, Bruce M. Jakosky, Stephen A. Ledvina

Publikováno v: Journal of Geophysical Research: Space Physics. 122:8391-8408

Daily averaged heavy ion escape rates from HALFSHEL hybrid simulations of the solar wind interaction with the Martian ionosphere are compared to the ion escape rates reported by Brain et al., [2015]. The simulation rates are found to be in agreement

The role of the Martian crustal magnetic fields in controlling ionospheric loss

Autor: Stephen H. Brecht, Stephen A. Ledvina

Publikováno v: Geophysical Research Letters. 41:5340-5346

A hybrid particle code has been used to examine the interaction of the solar wind with Mars. It is found that the presence of the crustal magnetic fields modifies the heavy ion (O+ and O2+) loss rates. In the case of the solar minimum situation the m

Ionospheric loss from Mars as predicted by hybrid particle simulations

Autor: Stephen H. Brecht, Stephen A. Ledvina, Stephen W. Bougher

Publikováno v: Journal of Geophysical Research: Space Physics. 121

This paper reports the results of hybrid simulations of the Mars-solar wind interaction. The focus is on the loss rates of O+ and O2+ from the Martian ionosphere while examining the importance of including 3-D dimensional neutral atmospheres with the

The orientation of Titan’s dayside ionosphere and its effects on Titan’s plasma interaction

Autor: Stephen A. Ledvina, Stephen H. Brecht, Thomas E. Cravens

Publikováno v: Earth, Planets and Space. 64:207-230

A hybrid particle code has been used to examine how Titan’s interaction with Saturn’s magnetosphere is effected by the orientation of the dayside ionosphere with respect to the incident magnetospheric flow. The hybrid code self-consistently inclu

Control of ion loss from Mars during solar minimum

Autor: Stephen A. Ledvina, Stephen H. Brecht

Publikováno v: Earth, Planets and Space. 64:165-178

A hybrid particle code has been used to examine the interaction of the solar wind with Mars during solar minimum. The results were surprising as they produced ion loss rates from Mars far in excess of what is estimated from MEX. The results are analy
