A simulation chamber for absorption spectroscopy in planetary atmospheres [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
A novel simulation chamber, PASSxS (Planetary Atmosphere Simulation System for Spectroscopy), has been developed for absorption measurements performed with a Fourier transform spectrometer (FTS) and, possibly, a cavity ring-down (CRD) spectrometer with ...

Superrotation in Planetary Atmospheres [PDF]

open access: yesSpace Science Reviews, 2020
AbstractSuperrotation is a dynamical regime where the atmosphere circulates around the planet in the direction of planetary rotation with excess angular momentum in the equatorial region. Superrotation is known to exist in the atmospheres of Venus, Titan, Jupiter, and Saturn in the solar system. Some of the exoplanets also exhibit superrotation.

Quantifying the Key Factors Affecting the Escape of Planetary Atmospheres

open access: yesThe Astrophysical Journal, 2023
The habitability of Earth-like planets is an increasingly important subject in astrophysics and in planetary sciences. Atmospheric escape plays a vital role in the evolution of the habitability of Earth-like planets.

Soft X-Ray-induced Dimerization of Methane

open access: yesThe Astrophysical Journal, 2023
Carbon 1s excitation of methane, CH _4 , has been studied in the gas phase using the ion trap integrated with the photon–ion instrument at PETRA III/DESY and soft X-rays from the beamline P04.

Depletion of 13C in CO in the Atmosphere of Mars Suggested by ExoMars-TGO/NOMAD Observations

open access: yesThe Planetary Science Journal, 2023
The atmosphere of Mars is mainly composed by carbon dioxide (CO _2 ). It has been predicted that photodissociation of CO _2 depletes ^13 C in carbon monoxide (CO).

Non-Thermal Nitric Oxide Formation in the Earth’s Polar Atmosphere

open access: yesAtmosphere, 2023
Auroral events are the prominent manifestation of solar/stellar forcing on planetary atmospheres because they are closely related to the stellar energy deposition by and evolution of planetary atmospheres.

Strong Depletion of 13C in CO Induced by Photolysis of CO2 in the Martian Atmosphere, Calculated by a Photochemical Model

open access: yesThe Planetary Science Journal, 2023
The isotopic signature of atmospheric carbon offers a unique tracer for the history of the Martian atmosphere and the origin of organic matter on Mars. The photolysis of CO _2 is known to induce strong isotopic fractionation of the carbon between CO _2 ...
