THE IMPRINT OF EXOPLANET FORMATION HISTORY ON OBSERVABLE PRESENT-DAY SPECTRA OF HOT JUPITERS (2016, background): “…Min et al. 2005), asteroids (as probed by meteorites) are deficient in carbon by a factor of & 10 (e.g. Wasson & Kallemeyn 1988), and the Earth is estimated to be carbon deficient in its bulk composition by a factor of ≈ 104 (e.g. Allègre et al. 2001), despite the high surface abundance of carbon.”
Water and astrobiology (2007, background): “Allegre et al. (2001) showed that Earth most closely resembles CI-chondrites in its Fe content and refractory element composition, and CM-chondrites in its moderately refractory elements.”
Nitrogen solubility in molten metal and silicate at high pressure and temperature (2012, background): “Estimates of nitrogen concentration in the silicate Earth are of order of 1–2 ppm (e.g. Marty, 1995; Allègre et al., 2001; Marty and Dauphas, 2003; Yokochi et al., 2009).”
Solubilities of O and Si in liquid iron in equilibrium with (Mg,Fe)SiO3 perovskite and the light elements in the core (2005, background): “Analysis of the meteorite data shows that the core needs to contain 5 to 7 wt% Si to reconcile the composition of bulk silicate Earth with that of carbonaceous chondrite [O’Neill, 1991; Allegre et al., 2001].”
The warm gas atmosphere of the HD 100546 disk seen by Herschel - Evidence of a gas-rich, carbon-poor atmosphere? (2012, background): “The carbon budget is important for planet formation, since the terrestrial planets in the inner solar system are known to have a deficit in carbon of three orders of magnitude relative to the solar abundance (Allègre et al. 2001).”
A PARAMETRIC MODELING APPROACH TO MEASURING THE GAS MASSES OF CIRCUMSTELLAR DISKS (2013, background): “Hence it is worth noting that, even without detailed modeling, the observations here have line-to-continuum ratios ∼ 1− 5 for the 13CO 2–1 line, which is much lower than the observed values, >∼ 100 for star forming cores in NGC 1333 (Sun et al. 2006; Lefloch et al. 1998).”
The chemical diversity of exo-terrestrial planetary debris around white dwarfs (2012, result): “6 for an alternative chemical model of the Earth by Allègre et al. 2001), these uncertainties are comparable to the errors in our abundance determinations.”
Stable-isotopic anomalies and the accretionary assemblage of the Earth and Mars: A subordinate role for carbonaceous chondrites (2011, background): “In terms of molybdenum isotopes, Earth, CI chondrites (Dauphas et al., 2002) and IAB/IIICD iron meteorites, all are similar, but various other differentiated meteorites and non-CI chondrites show positive anomalies (Burkhardt et al., 2010).”
The sulfur content of volcanic gases on Mars (2009, methodology): “%) has been more recently proposed (Allègre et al., 2001), also based on volatility trends.”
Urey ratio and the structure and evolution of Earth's mantle (2008, background): “Geochemical models for Earth’s composition suggest that the present-day internal heat production is about 20 TW [e.g., McDonough and Sun, 1995; Allègre et al., 2001; Lyubetskaya and Korenaga, 2007a], so the rest of the surface heat flux must be from secular cooling.”
