An orbital window into the ancient Sun's mass [PDF]
Models of the Sun's long-term evolution suggest that its luminosity was substantially reduced 2-4 billion years ago, which is inconsistent with substantial evidence for warm and wet conditions in the geological records of both ancient Earth and Mars ...

Nonequilibrium thermodynamics of circulation regimes in optically-thin, dry atmospheres [PDF]
An extensive analysis of an optically-thin, dry atmosphere at different values of the thermal Rossby number Ro and of the Taylor number Ff is per- formed with a general circulation model by varying the rotation rate {\Omega} and the surface drag {\tau ...

High-Fidelity Archeointensity Results for the Late Neolithic Period From Central China [PDF]
Archeomagnetism focuses on exploring high-resolution variations of the geomagnetic field over hundreds to thousands of years. In this study, we carried out a comprehensive study of chronology, absolute and relative paleointensity on a late Neolithic site

The Effect of Multiple Heat Sources on Exomoon Habitable Zones [PDF]
With dozens of Jovian and super-Jovian exoplanets known to orbit their host stars in or near the stellar habitable zones, it has recently been suggested that moons the size of Mars could offer abundant surface habitats beyond the solar system.

Earth’s polar night boundary layer as an analogue for dark side inversions on synchronously rotating terrestrial exoplanets [PDF]
A key factor in determining the potential habitability of synchronously rotating planets is the strength of the atmospheric boundary layer inversion between the dark side surface and the free atmosphere.
