Hydrodynamic escape from the proto-lunar disk and the origin of the Earth-Moon volatile dichotomy
Kaveh Pahlevan, Andrew N. Youdin, Paolo A. Sossi
Volatile elements - those that vaporize at low temperatures - are depleted in lunar rocks relative to terrestrial rocks. This systematic chemical depletion is evidence for vaporiza…
A hybrid origin for the Martian atmosphere
Kaveh Pahlevan, Laura Schaefer, Don Porcelli
The Martian isotopic record displays a dichotomy in volatile compositions. Interior volatiles from the mantle record a chondritic heritage (e.g., H, N, Kr, Xe) whereas the atmosphe…
A primordial atmospheric origin of hydrospheric deuterium enrichment on Mars
Kaveh Pahlevan, Laura Schaefer, Linda T. Elkins-Tanton +2
The deuterium-to-hydrogen (D/H or 2H/1H) ratio of Martian atmospheric water (~6x standard mean ocean water, SMOW) is higher than that of known sources, requiring planetary enrichme…
Origin of the Moon
Robin M. Canup, Kevin Righter, Nicolas Dauphas +8
The Earth-Moon system is unusual in several respects. The Moon is roughly 1/4 the radius of the Earth - a larger satellite-to-planet size ratio than all known satellites other than…
Hydrogen isotopic evidence for early oxidation of silicate Earth
Kaveh Pahlevan, Laura Schaefer, Marc M. Hirschmann
The Moon-forming giant impact extensively melts and partially vaporizes the silicate Earth and delivers a substantial mass of metal to Earth's core. Subsequent evolution of the mag…
Life Beyond the Solar System: Remotely Detectable Biosignatures
Shawn Domagal-Goldman, Nancy Y. Kiang, Niki Parenteau +38
For the first time in human history, we will soon be able to apply the scientific method to the question "Are We Alone?" The rapid advance of exoplanet discovery, planetary systems…
Speciation and Dissolution of Hydrogen in the Proto-Lunar Disk
Kaveh Pahlevan, Shun-ichiro Karato, Bruce Fegley
Despite very high temperatures accompanying lunar origin, indigenous water in the form of OH has been unambiguously observed in Apollo samples in recent years. Such observations ha…
Collisionless Encounters and the Origin of the Lunar Inclination
Kaveh Pahlevan, Alessandro Morbidelli
The Moon is generally thought to have formed from the debris ejected by the impact of a planet-sized object with the proto-Earth towards the end of planetary accretion. Modeling of…
Chemical Fractionation in the Silicate Vapor Atmosphere of the Earth
Kaveh Pahlevan, David Stevenson, John Eiler
Despite its importance to questions of lunar origin, the chemical composition of the Moon is not precisely known. In recent years, however, the isotopic composition of lunar sample…
Equilibration in the Aftermath of the Lunar-Forming Giant Impact
Kaveh Pahlevan, David Stevenson
Simulations of the moon-forming impact suggest that most of the lunar material derives from the impactor rather than the Earth. Measurements of lunar samples, however, reveal an ox…
