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 ...

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

Soft X-Ray-induced Dimerization of Methane
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.

Global-mean Vertical Tracer Mixing in Planetary Atmospheres. I. Theory and Fast-rotating Planets [PDF]
Most chemistry and cloud formation models for planetary atmospheres adopt a one-dimensional (1D) diffusion approach to approximate the global-mean vertical tracer transport.

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

Radiative transfer and inversion codes for characterizing planetary atmospheres: an overview
The study of planetary atmospheres is crucial for understanding the origin, evolution, and processes that shape celestial bodies like planets, moons and comets.

Susceptibility of planetary atmospheres to mass loss and growth by planetesimal impacts: the impact shoreline [PDF]
This paper considers how planetesimal impacts affect planetary atmospheres. Atmosphere evolution depends on the ratio of gain from volatiles to loss from atmosphere stripping fv; for constant bombardment, atmospheres with fv < 1 are destroyed in finite

Study of atmospheres in the solar system, from stellar occultation or planetary transit
Stellar occultations and transits occur when a planetary body passes in front of a star (including our Sun). For objects with an atmosphere, refraction plays an essential role to explain the drops of flux and the aureoles observed during these events ...

Earth shaped by primordial H_2 atmospheres [PDF]
Thermodynamic modelling shows that Earth’s water, core density and overall oxidation state can be explained by the formation of Earth from planetary embryos with hydrogen-rich primary atmospheres and underlying magma oceans.

. Baroclinic and barotropic instabilities are well known as the mechanisms responsible for the production of the dominant energy-containing eddies in the atmospheres of Earth and several other planets, as well as Earth's oceans. Here we consider insights
