The Science of Sungrazers, Sunskirters, and Other Near-Sun Comets
Space Science Reviews, 2017 This review addresses our current understanding of comets that venture close to the Sun, and are hence exposed to much more extreme conditions than comets that are typically studied from Earth. The extreme solar heating and plasma environments that these

Ensemble properties of comets in the Sloan Digital Sky Survey [PDF]
Icarus, 2012 We present the ensemble properties of 31 comets (27 resolved and 4 unresolved) observed by the Sloan Digital Sky Survey (SDSS). This sample of comets represents about 1 comet per 10 million SDSS photometric objects.

Terrestrial deuterium-to-hydrogen ratio in water in hyperactive comets [PDF]
Astronomy & Astrophysics, 2019 The D/H ratio in cometary water has been shown to vary between 1 and 3 times the Earth’s oceans value, in both Oort cloud comets and Jupiter-family comets originating from the Kuiper belt.
