Do intrinsic magnetic fields protect planetary atmospheres from stellar winds? lessons from ion measurements at Mars, Venus, and Earth

R Ramstad, S Barabash - Space Science Reviews, 2021 - Springer
The accumulation of detailed ion flux measurements from long-lived spacecraft orbiting the
solar system's terrestrial planets have enabled recent studies to estimate the rate of solar …

Synergies between Venus & exoplanetary observations: Venus and its extrasolar siblings

MJ Way, C Ostberg, BJ Foley, C Gillmann… - Space Science …, 2023 - Springer
Here we examine how our knowledge of present day Venus can inform terrestrial
exoplanetary science and how exoplanetary science can inform our study of Venus. In a …

The spatial distribution of planetary ion fluxes near Mars observed by MAVEN

DA Brain, JP McFadden, JS Halekas… - Geophysical …, 2015 - Wiley Online Library
We present the results of an initial effort to statistically map the fluxes of planetary ions on a
closed surface around Mars. Choosing a spherical shell~ 1000 km above the planet, we …

In‐situ measurements of ion density in the Martian ionosphere: Underlying structure and variability observed by the MAVEN‐STATIC instrument

CM Fowler, J McFadden, KG Hanley… - Journal of …, 2022 - Wiley Online Library
Measurement of the dense cold thermal plasma in planetary ionospheres via orbiting
spacecraft is challenging because ion energies are small (0–4 eV), densities can vary by …

The Martian atmospheric ion escape rate dependence on solar wind and solar EUV conditions: 1. Seven years of Mars Express observations

R Ramstad, S Barabash, Y Futaana… - Journal of …, 2015 - Wiley Online Library
More than 7 years of ion flux measurements in the energy range 10 eV–15 keV have
allowed the ASPERA‐3/IMA (Analyzer of Space Plasmas and Energetic Ions/Ion Mass …

Heavy ion escape from Mars, influence from solar wind conditions and crustal magnetic fields

H Nilsson, NJT Edberg, G Stenberg, S Barabash… - Icarus, 2011 - Elsevier
We have used more than 4years of Mars Express ion data to estimate the escape of heavy
ions (O+, O2+ and CO2+) from Mars. To take the limited field of view of the instrument into …

The effect of solar wind variations on the escape of oxygen ions from Mars through different channels: MAVEN observations

E Dubinin, M Fraenz, M Pätzold… - Journal of …, 2017 - Wiley Online Library
We present multi‐instrument observations of the effects of solar wind on ion escape fluxes
on Mars based on the Mars Atmosphere and Volatile EvolutioN (MAVEN) data from 1 …

Mars‐ward ion flows in the martian magnetotail: Mars express observations

C Zhang, Y Futaana, H Nilsson, Z Rong… - Geophysical …, 2022 - Wiley Online Library
We investigate Mars‐ward planetary ions (O+ and O2+) in the Martian magnetotail that
potentially reduce the amount of escaping ions. The global properties of Mars‐ward flows in …

Global Mars‐solar wind coupling and ion escape

R Ramstad, S Barabash, Y Futaana… - Journal of …, 2017 - Wiley Online Library
Loss of the early Martian atmosphere is often thought to have occurred due to an effective
transfer of the solar wind energy through the Martian induced magnetic barrier to the …

Mars‐solar wind interaction: LatHyS, an improved parallel 3‐D multispecies hybrid model

R Modolo, S Hess, M Mancini, F Leblanc… - Journal of …, 2016 - Wiley Online Library
In order to better represent Mars‐solar wind interaction, we present an unprecedented
model achieving spatial resolution down to 50 km, a so far unexplored resolution for global …
