Cryogenic Differential Calorimetry: Exothermicity of Amorphous-to-crystalline Phase Transitions (ACPT) in Astrophysical and Cometary Ice Analogs

The Astrophysical Journal
Amorphous ice is understood to be the predominant phase of water in cometary nuclei. A significant number of other volatiles can be trapped in amorphous H _2 O ice and released during the amorphous-to-crystalline phase transition (ACPT).

Cometary evolution : clues on physical properties from chondritic interplanetary dust particles

, 1997
The degree of diversity or similarity detected in comets depends primarily on the lifetimes of the individual cometary nuclei at the time of analysis. It is inherent in our understanding of cometary orbital dynamics and the seminal model of comet origins

Comet 46P/Wirtanen, the target of the Rosetta mission

, 1998
We present a summary of the observational data on periodic comet 46P/Wirtanen, emphasizing the recent estimates of H2O production rate from narrow-band photometry and CCD imaging with ensuing estimates of the photometric cross-section of the nucleus.
