On nature of evolution of short-period comets. On the question of short-period comets evolution
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007 The main hypothesis of short-period comets evolution are considered. Basing on the performed researches we conclude that the main sources of short-period comets are: main asteroid belt, relict asteroid belts between giant planets and the Kuiper belt.

The Astronomical Journal, 2023 Short-period comet 108P/Ciffreo is known for its peculiar double morphology, in which the nucleus is accompanied by a comoving, detached, diffuse “blob.” We report new observations of 108P/Ciffreo taken with the Hubble Space Telescope and the Nordic ...

CO and CO2 Productions Rates of Comets Observed by NEOWISE within Year 1 of the Reactivated Mission
The Planetary Science Journal, 2023 We report on the observed fluxes of the comets detected by NEOWISE during the first year of operations after the spacecraft’s reactivation. The sample included 57 comets.

Comet P/2021 HS (PANSTARRS) and the Challenge of Detecting Low-activity Comets
The Planetary Science Journal, 2023 Jupiter-family comet (JFC) P/2021 HS (PANSTARRS) only exhibits a coma within a few weeks of its perihelion passage at 0.8 au, which is atypical for a comet.

Analysis of CN Coma Morphology Features of Comet 21P/Giacobini–Zinner
The Planetary Science Journal, 2023 We analyze jet features found in the coma of comet 21P/Giacobini–Zinner (21P/GZ) during its 2018 perihelion passage using narrowband CN photometric imaging in order to determine the comet’s rotational period, and we constrain the CN gas outflow velocity ...

Six Outbursts of Comet 46P/Wirtanen
The Planetary Science Journal, 2021 Cometary activity is a manifestation of sublimation-driven processes at the surface of nuclei. However, cometary outbursts may arise from other processes that are not necessarily driven by volatiles.

Optical Imaging Polarimetry of Comet 21P/Giacobini–Zinner during Its 2018 Apparition
The Planetary Science Journal, 2023 We conducted polarimetric observations of comet 21P/Giacobini–Zinner in the optical wavelength region using the polarimetric imager PICO equipped with the 50 cm telescope for Public Outreach at the Mitaka Campus of the National Astronomical Observatory ...

Origin and Evolution of Short-period Comets [PDF]
The Astrophysical Journal, 2017 Abstract Comets are icy objects that orbitally evolve from the trans-Neptunian region into the inner solar system, where they are heated by solar radiation and become active due to the sublimation of water ice. Here we perform simulations in which cometary reservoirs are formed in the early solar system and evolved over 4.5 Gyr.

Dust Properties of Comets Observed by Spitzer
The Planetary Science Journal, 2023 As comets journey into the inner solar system, they deliver particulates and volatile gases into their comae that reveal the most primitive materials in the solar system.

Stochastic capture of short-period comets [PDF]
Monthly Notices of the Royal Astronomical Society, 1989 Un modele d'orbite de comete a courte periode, incluant les perturbations dues aux planetes, est developpe. La capture de ces cometes est analysee en faisant varier l'inclinaison et le perihelie.
