Earth and Planetary Physics, 2022 Tailward ion outflows in the Martian-induced magnetotail are known to be one of the major channels for Martian atmospheric escape. On the basis of nearly 6.5 years of observations from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, we ...

The freeze-out mechanism and phase-space density in ultrarelativistic heavy-ion collisions [PDF]
, 2002 We explore the consequences of a freeze-out criterion for heavy-ion collisions, based on pion escape probabilities from the hot and dense but rapidly expanding collision region.

Solar forcing and planetary ion escape from Mars [PDF]
Geophysical Research Letters, 2008 The variability of planetary ion escape from Mars is studied using data from the Ion Mass Analyzer, IMA, on Mars Express (MEX). 42 orbits were selected during 17 months for different solar wind conditions, focusing on the low energy (≈30 – 800 eV) heavy ion (e.g. O+, O2+ and CO2+) outflow. A strong correlation is found between solar wind forcing of the

Observations of fast anisotropic ion heating, ion cooling, and ion recycling in large-amplitude drift waves [PDF]
, 1998 Large-amplitude drift wave fluctuations are observed to cause severe ion temperature oscillations in plasmas of the Caltech Encore tokamak [J. M. McChesney, P. M. Bellan, and R. A. Stern, Phys. Fluids B 3, 3370 (1991)]. Experimental investigations of the

IMF-induced escape of molecular ions from the Martian ionosphere [PDF]
Annales Geophysicae, 2013 Since Mars does not possess a significant global intrinsic magnetic field, the solar wind interacts directly with the Martian ionosphere and can induce ion escapes from it.

Pickup ion measurements by MAVEN: A diagnostic of photochemical oxygen escape from Mars [PDF]
, 2014 A key process populating the oxygen exosphere at Mars is the dissociative recombination of ionospheric O 2 + , which produces fast oxygen atoms, some of which have speeds exceeding the escape speed and thus contribute to atmospheric loss.

Reionization constraints using Principal Component Analysis [PDF]
, 2010 Using a semi-analytical model developed by Choudhury & Ferrara (2005) we study the observational constraints on reionization via a principal component analysis (PCA).

Survey of pickup ion signatures in the vicinity of Titan using CAPS/IMS [PDF]
, 2016 Pickup ion detection at Titan is challenging because ion cyclotron waves are rarely detected in the vicinity of the moon. In this work, signatures left by freshly produced pickup heavy ions (m/q ∼ 16 to m/q ∼ 28) as detected in the plasma data by the ...

The Venusian Atmospheric Oxygen Ion Escape: Extrapolation to the Early Solar System
Journal of Geophysical Research: Planets, 2020 The present atmosphere of Venus contains almost no water, but recent measurements indicate that in its early history, Venus had an Earth‐like ocean. Understanding how the Venusian atmosphere evolved is important not only for Venus itself but also for ...
