• Organic molecules in protoplanetary disks around T Tauri and Herbig Ae stars (2004, background): “The picture is not complete since CO can be converted to CO2, whose abundance is high in interstellar ices (e.g., Ehrenfreund & Charnley 2000) but less well known in comets (10% in comet 22P/Kopff, Crovisier et al. 1999).”
• Laboratory Studies on the Irradiation of Methane in Interstellar, Cometary, and Solar System Ices (2006, background): “Methane is also found to be abundant throughout the solar system (Ehrenfreund & Charnley 2000; Roush 2001).”

• Complex organic molecules in protoplanetary disks (2013, background): “…identification of glycine in a sample returned from comet 81P/Wild 2 (Elsila et al. 2009) and the detection of numerous amino acids in meteorites, some of which are either very rare on Earth or, indeed, unknown in terrestrial biochemistry (for an overview, see, e.g., Ehrenfreund & Charnley 2000).”
• Hot corinos in NGC 1333-IRAS4B and IRAS2A (2006, background): “This picture is, at least partially, supported by the fact that some complex organic molecules are found both in hot corinos and in comets (e.g., methyl cyanide CH3CN, methyl formate HCOOCH3, and formic acid HCOOH; Ehrenfreund & Charnley 2000).”
• Grain Surface Models and Data for Astrochemistry (2017, background): “…pristine ices can be processed by the heating and enhanced irradiation associated with the star-formation process, potentially forming even more complex volatile and refractory organic compounds, including amino acids (Kvenvolden et al. 1970; Ehrenfreund and Charnley 2000; Elsila et al. 2009).”
• Formation of methyl formate and other organic species in the warm-up phase of hot molecular cores (2006, background): “…incapable of reproducing astronomically observed abundances at temperatures of ∼100 K. Numerous allusions have been made (e.g. Charnley et al. 1995; Ehrenfreund & Charnley 2000; Cazaux et al. 2003; Peeters et al. 2006) to the possibility that methyl formate is produced on dust-grain surfaces at…”
• A THREE-PHASE CHEMICAL MODEL OF HOT CORES: THE FORMATION OF GLYCINE (2013, background): “However, numerous amino acids have been found in meteorites, and glycine was recently detected in a sample taken from comet Wild 2 (Elsila et al. 2009); it has indeed been postulated that terrestrial amino acids may have an interstellar origin (e.g. Ehrenfreund & Charnley 2000).”
• Astrochemistry and compositions of planetary systems (2020, background): “The distributions of organic molecules in disks are of special interest because of their connection to complex organic molecules in comets and asteroids (Ehrenfreund and Charnley 2000; Altwegg et al. 2019), and therefore possible connection to prebiotic chemistry on planets following asteroid and co”
