Analysis of CCD images of the coma of comet P/Halley [PDF]
, 1992 The modeling analysis objective of this project is to make use of the skill acquired in the development of Monte Carlo particle trajectory models for the distributions of gas species in cometary comae as a basis for a new dust coma model. This model will

The Astrophysical JournalWe present time series medium-band ( R ∼ 20–40) observations of the third interstellar object (ISO) 3I/ATLAS (C/2025 N1) obtained with the 7-Dimensional Telescope, which enabled spatially resolved monitoring of its gas and dust activity from 2025 July to

Phase angle dependency of the dust cross section in a cometary coma [PDF]
Rosetta/OSIRIS took optical measurements of the intensity of scattered light from the coma of 67P/Churyumov-Gerasimenko over a wide range of phase angles. These data have been used to measure the phase angle dependent radiance profile of the dust coma.

An analysis of CCD images of the coma of Comet Halley [PDF]
, 1990 The analysis of selected CCD images of the coma of comet P/Halley is presented. The images were taken using specially designed filters that isolate regions of a comet's spectrum such that only sunlight which has been scattered by the dust in the coma is ...

The Planetary Science JournalConventional narrowband photoelectric photometry of Comet Hale–Bopp (1995 O1) was obtained on 99 nights from mid-1995 to early-2000, yielding gas and dust production rates over an unprecedented range of time and distance. The appearance of Hale–Bopp (H-B)

Dust morphology of comet Hale-Bopp (C/1995 O1): i. Pre-perihelion coma structures in 1996
, 1997 In 1996 comet Hale-Bopp exhibited a porcupine-like coma with straight jets of dust emission from several ective regions on the nucleus. The multi-jet coma geometry developed during the first half of 1996.

Spatial Distribution of H2O+ Ions in the Inner Coma of C/2014 Q2 (Lovejoy)
The Astrophysical JournalNeutral molecules that sublimate from cometary ices (mainly water at ∼1 au from the Sun) are ionized due to solar extreme-ultraviolet radiation and collisions with highly energetic electrons.
