Carbon from Interstellar Clouds to Habitable Worlds
Edwin A. Bergin, Marc M. Hirschmann, Andre Izidoro
Carbon is an essential element for a habitable world. Inner (r < 3 au) disk planetary carbon compositions are strongly influenced by supply and survival of carbonaceous solids. Her…
Soot Planets instead of Water Worlds
Jie Li, Edwin A. Bergin, Marc M. Hirschmann +3
Some low-density exoplanets are thought to be water-rich worlds that formed beyond the snow line of their protoplanetary disc, possibly accreting coequal portions of rock and water…
Exoplanet Volatile Carbon Content as a Natural Pathway for Haze Formation
E. A. Bergin, E. Kempton, M. Hirschmann +5
We explore terrestrial planet formation with a focus on the supply of solid-state organics as the main source of volatile carbon. For the water-poor Earth, the water ice line, or i…
Early volatile depletion on planetesimals inferred from C-S systematics of iron meteorite parent bodies
Marc M. Hirschmann, Edwin A. Bergin, Geoff A. Blake +2
During the formation of terrestrial planets, volatile loss may occur through nebular processing, planetesimal differentiation, and planetary accretion. We investigate iron meteorit…
Earth's carbon deficit caused by early loss through irreversible sublimation
Jie Li, Edwin A. Bergin, Geoffrey A. Blake +2
Carbon is an essential element for life but its behavior during Earth's accretion is not well understood. Carbonaceous grains in meteoritic and cometary materials suggest that irre…
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…
