Probing the Viscosity of Venus's Mantle From Dynamic Topography at Baltis Vallis
Nathan McGregor + Alain Plattner + Cedric Gillmann ...
The Baltis Vallis channel on Venus preserves a record of long‐wavelength deformation generated by a convecting mantle, providing a unique window into the planet's geodynamics....

Microwave Emissivity Variations Across Ovda Regio, Venus
Indujaa Ganesh + Martha S Gilmore
The surface composition of highland tesserae on Venus critically constrains the geologic and climate history of the planet. We examine one such highland, Ovda Regio, which...

Atmospheric Loss from Venus-like Planets Orbiting G Stars
Dave A Brain + Aimee W Merkel + Akifumi Nakayama ...
Atmospheric escape to space is a key mechanism by which planetary atmospheres evolve. Escape can occur via several different processes that remove atmospheric particles in...

Meridional Distribution of CO, H2O, and H2SO4 in the Venus' Atmosphere: A Two‐Dimensional Model Incorporating Transport and Chemical Reaction
Shinya Kuwayama + George L Hashimoto
We developed a 2‐dimensional model of Venus' atmosphere which calculates meridional distributions of chemical species such as CO, H2 ${\mathrm{H}}_{2}$O, and H2SO4 ${\mathrm{H}}_{2}{\text{SO}}_{4}$....

Influence of Possible Bulk Compositions on the Long-Term Evolution and Outgassing of Venus
Diogo José Louro Lourenço + Maria Grünenfelder + Oliver Shah ...
Venus’ mass and radius are similar to those of Earth. However, Venus’ interior structure and chemical composition are poorly constrained. Seemingly small deviations from the...
