The Cosmic Shoreline Revisited: A Metric for Atmospheric Retention Informed by Hydrodynamic Escape [PDF]
The Astrophysical JournalThe “cosmic shoreline,” a semi-empirical relation that separates airless worlds from worlds with atmospheres as proposed by K. J. Zahnle & D. C. Catling, is now guiding large-scale JWST surveys aimed at detecting rocky exoplanet atmospheres.

The influence of upper boundary conditions on molecular kinetic atmospheric escape simulations [PDF]
Planetary and Space Science, 2021 Molecular kinetic simulations are typically used to accurately describe the tenuous regions of the upper atmospheres on planetary bodies. These simulations track the motion of particles representing real atmospheric atoms and/or molecules subject to ...

On the Dual Nature of Atmospheric Escape
The Astrophysical JournalPlanetary atmospheres cannot remain hydrostatic at all altitudes because they approach finite density at infinite radius, implying infinite mass. Classical treatments address this in two directions: either retain a hydrostatic structure while allowing ...

Atmospheric Escape From Earth and Mars: Response to Solar and Solar Wind Drivers of Oxygen Escape
Geophysical Research LettersHabitability at the surface of a planet depends on having an atmosphere long enough for life to develop. The loss of atmosphere to space is an important component in assessing planetary surface habitability.

Effects of a Weak Intrinsic Magnetic Field on Atmospheric Escape From Mars
Geophysical Research Letters, 2018 The magnetization of a planet significantly changes the nature of atmospheric escape, and the question of whether a planetary field shields atmosphere from erosion by the solar wind or not remains open.

Wind‐induced atmospheric escape: Titan [PDF]
Geophysical Research Letters, 2012 Rapid thermospheric flows can significantly enhance the atmospheric loss rates and structures of atmospheric coronae of planetary bodies. Using descriptions of atmospheric escape based on molecular kinetic models, we show that such flows at the exobase of Titan could significantly increase the calculated constituent thermal and nonthermal escape rates.

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 ...

The Variable Detection of Atmospheric Escape around the Young, Hot Neptune AU Mic b [PDF]
Astronomical Journal, 2023 Photoevaporation is a potential explanation for several features within exoplanet demographics. Atmospheric escape observed in young Neptune-sized exoplanets can provide insight into and characterize which mechanisms drive this evolution and at what ...
