Planetary Trojans – the main source of short period comets? [PDF]

International Journal of Astrobiology, 2010
AbstractOne of the key considerations when assessing the potential habitability of telluric worlds will be that of the impact regime experienced by the planet. In this work, we present a short review of our understanding of the impact regime experienced by the terrestrial planets within our own Solar system, describing the three populations of ...

The Dust Environment of Short Period Comets [PDF]

, 2013
In this work we present a characterization of the dust environment of various Short Period Comets, with the purpose to improve the knowledge on their physical properties. Among this comet family members, we focused over 30P/Reinmuth 1, 78P/Gehrels 2, 123P/West-Hartley and P/2011 W2 (Rinner).

Studies of short-period comets on the eve of Rosetta [PDF]

, 2015
We present an extended study of the dust environment of a sample of short-period comets and their dynamical history. With this aim, we characterized the dust tails when the comets are active, and we make a statistical study to determine their dynamical evolution.

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.

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.

Application of the regularization method to differential equations of comets' motion

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2009
Regularization method for differential equation of comets' motion is used. Numerical integration of the equation of motion of 10 short-period comets during the period of 1800 to 2204 with the use of osculating elements of the large planets is done.

Monitoring Cometary Activity of 60P/Tsuchinshan During Its 2018–2019 Apparition

The Astrophysical Journal, 2023
Comet 60P/Tsuchinshan is a Jupiter family comet. Since the discovery of 60P/Tsuchinshan, little research for cometary activity has been conducted on this comet, though it has returned to perihelion several times.
