Anomalous transient enhancement of planetary ion escape at Mars [PDF]
Nature CommunicationsAtmospheric ion escape plays a crucial role in the evolution of planetary climate and habitability. While Mars has been the focus of extensive in-situ spacecraft observations, our understanding of ion escape at Mars has been constrained by single-point ...

Estimating ion escape from unmagnetized planets [PDF]
Annales Geophysicae, 2022 We propose a new method to estimate ion escape from unmagnetized planets that combines observations and models. Assuming that upstream solar wind conditions are known, a computer model of the interaction between the solar wind and the planet is executed

Species-dependent ion escape on Titan [PDF]
Earth and Planetary Physics, 2019 Cassini observations over the past ten years have revealed that Titan possesses a chemically complex ionosphere. In this study, we investigate the relative contributions of different ion species to the total ion escape on Titan, by dividing all ion ...

Closed magnetic topology in the Venusian magnetotail and ion escape at Venus [PDF]
Nature CommunicationsVenus, lacking an intrinsic global dipole magnetic field, serves as a textbook example of an induced magnetosphere, formed by interplanetary magnetic fields (IMF) enveloping the planet.

Terrestrial ion escape and relevant circulation in space [PDF]
Annales Geophysicae, 2019 Observations of the terrestrial ion escape to space and the transport of escaping ions in the magnetosphere are reviewed, with the main stress on subjects that were not covered in reviews over past 2 decades, during which Cluster has significantly ...

Centrifugally Stimulated Exospheric Ion Escape at Mercury [PDF]
Geophysical Research Letters, 2012 We investigate the transport of ions in the low-altitude magnetosphere magnetosphere of Mercury. We show that, because of small spatial scales, the centrifugal effect due to curvature of the E B drift paths can lead to significant particle energization ...

Effects of ion composition on escape and morphology on Mars [PDF]
Annales Geophysicae, 2023 We refine a recently presented method to estimate ion escape from non-magnetized planets and apply it to Mars. The method combines in situ observations and a hybrid plasma model (ions as particles, electrons as a fluid). We use measurements from the Mars

Heavy Ion Escape at Mars during the Disappearing Solar Wind Event in 2022 December
The Astrophysical JournalA unique event known as the disappearing solar wind (DSW), characterized by an extremely low-density solar wind stream, occurred at Mars on 2022 December 26–27.

Stellar wind interaction and pick-up ion escape of the Kepler-11 "super-Earths" [PDF]
, 2014 We study the interactions between stellar wind and the extended hydrogen-dominated upper atmospheres of planets and the resulting escape of planetary pick-up ions from the 5 "super-Earths" in the compact Kepler-11 system and compare the escape rates with

The Influence of Solar Irradiation and Solar Wind Conditions on Heavy Ion Escape from Mars
Journal of Geophysical Research: Space Physics, 2023 We apply a recently proposed method to estimate heavy ion escape from Mars. The method combines in situ observations with a hybrid plasma model, which treats ions as particles and electrons as a fluid.
