Ohmic Dissipation in the Atmospheres of Hot Jupiters [PDF]
, 2010 Hot Jupiter atmospheres exhibit fast, weakly-ionized winds. The interaction of these winds with the planetary magnetic field generates drag on the winds and leads to ohmic dissipation of the induced electric currents. We study the magnitude of ohmic dissipation in representative, three-dimensional atmospheric circulation models of the hot Jupiter HD ...

The Planetary Science JournalMercury has a very tenuous atmosphere starting at the surface, which is referred to as a surface-bound exosphere, where there are no collisions between exospheric particles.

The Possible role of Penning Ionization Processes in Planetary Atmospheres
, 2015 In this paper we suggest Penning ionization as an important route of formation for ionic species in upper planetary atmospheres. Our goal is to provide relevant tools to researchers working on kinetic models of atmospheric interest, in order to include ...

Meteoric Layers in Planetary Atmospheres [PDF]
Space Science Reviews, 2008 Metallic ions coming from the ablation of extraterrestrial dust, play a significant role in the distribution of ions in the Earth’s ionosphere. Ions of magnesium and iron, and to a lesser extent, sodium, aluminium, calcium and nickel, are a permanent feature of the lower E-region.

Star-planet magnetic interaction and evaporation of planetary atmospheres [PDF]
, 2013 Stars interact with their close-in planets through radiation, gravitation, and magnetic fields. We investigate the energy input to a planetary atmosphere by reconnection between stellar and planetary magnetic fields and compare it to the energy input of ...

Characterization of Planetary Atmospheres
, 2020 After the discovery of the first exoplanet in 1990’s and a fast growing number of discoveries since then, there have been many attempts to observe and characterize their atmospheres. In particular, water and methane have been the focus of many investigations due to their relevance to the origin of life and habitability, as well as their major roles to ...

Climate Regimes across the Habitable Zone: A Comparison of Synchronous Rocky M and K Dwarf Planets
The Astrophysical JournalM and K dwarf stars make up 86% of the stellar population and host many promising astronomical targets for detecting habitable climates in the near future.

AN ANALYTIC RADIATIVE–CONVECTIVE MODEL FOR PLANETARY ATMOSPHERES [PDF]
, 2012 We present an analytic one-dimensional radiative–convective model of the thermal structure of planetary atmospheres. Our model assumes that thermal radiative transfer is gray and can be represented by the two-stream approximation.

Climatology of the Martian Polar Regions: Three Mars Years of CRISM/MARCI Observations of Atmospheric Clouds and Dust [PDF]
Lunar and Planetary Science Conference (2013) vol. 44, p.1874, 2013 We present the synthesis of CRISM EPF and MARCI data to examine the evolution of atmospheric water ice and dust opacity at both poles for MY 28-30.
