Organic solids produced from simple C/H/O/N ices by charged particles: applications to the outer solar system.
Khare BN, Thompson WR, Chyba CF, Arakawa ET, Sagan C. Khare BN, et al. Among authors: chyba cf. Adv Space Res. 1989;9(2):41-53. doi: 10.1016/0273-1177(89)90362-1. Adv Space Res. 1989. PMID: 11537360
The chromophore is a yellowish to tan organic material (a tholin) which we have studied by UV-VIS reflection and transmission, and IR transmission spectroscopy. Its yield, -1 C keV-1, implies substantial production of organic solids by the action of cosmic rays and radionu …

The heliocentric evolution of cometary infrared spectra: results from an organic grain model.
Chyba CF, Sagan C, Mumma MJ. Chyba CF, et al. Icarus. 1989;79:362-81. doi: 10.1016/0019-1035(89)90083-3. Icarus. 1989. PMID: 11542163
Observations of Comets Halley and Wilson reveal an emission feature peaking near 3.4 micrometers, characteristic of C-H stretching in hydrocarbons. We have previously (Chyba and Sagan 1987a, Nature (London) 330, 350-353) fit this feature with a simple two-component …
