Mid-infrared spectra of comet nuclei
Sign Up to like & getrecommendations! Published in 2017 at "Icarus"
DOI: 10.1016/j.icarus.2016.11.029
Abstract: Abstract Comet nuclei and D-type asteroids have several similarities at optical and near-IR wavelengths, including near-featureless red reflectance spectra, and low albedos. Mineral identifications based on these characteristics are fraught with degeneracies, although some general… read more here.

Unusually high CO abundance of the first active interstellar comet
Sign Up to like & getrecommendations! Published in 2020 at "Nature Astronomy"
DOI: 10.1038/s41550-020-1087-2
Abstract: Comets spend most of their lives at large distances from any star, during which time their interior compositions remain relatively unaltered. Cometary observations can therefore provide direct insight into the chemistry that occurred during their… read more here.

Thermal stresses as a possible mechanism for initiating the destruction of comet Shoemaker-Levy 9
Sign Up to like & getrecommendations! Published in 2025 at "Monthly Notices of the Royal Astronomical Society"
DOI: 10.1093/mnras/staf081
Abstract: It is now widely accepted that the breakup of comet Shoemaker-Levy 9 (SL9) was caused by tidal forces. This explanation applies to bodies that enter a planet’s Roche zone and have a loose “rubble pile”… read more here.
