A targeted search for Main Belt Comets [PDF]

Monthly Notices of the Royal Astronomical Society, 2022
Main Belt Comets (MBCs) exhibit sublimation-driven activity while occupying asteroid-like orbits in the Main Asteroid Belt. MBCs and candidates show stronger clustering of their longitudes of perihelion around 15° than other objects from the Outer Main ...

The activity of main belt comets [PDF]

Astronomy & Astrophysics, 2012
Context. Main belt comets represent a recently discovered class of objects. They are quite intriguing because, while having a Tisserand invariant value higher than 3, are showing cometary activity. Aims.

Dynamical constraints on the origin of Main Belt comets [PDF]

Meteoritics & Planetary Science, 2009
In an effort to understand the origin of Main Belt comets (MBCs) 7968 Elst-Pizzaro, 118401, and P/2005 U1, the dynamics of these three icy asteroids and a large number of hypothetical MBCs were studied.

Are the main belt comets, comets? [PDF]

Proceedings of the International Astronomical Union, 2009
AbstractWe present the visible spectrum of asteroid-comet transition object 133P/Elst-Pizarro (7968), the first member of the new population of objects called Main Belt Comets (Hsieh & Jewitt 2006). The spectrum was obtained with the 4.2m William Herschel Telescope at the “Roque de los Muchachos” observatory.

Castalia — A Mission to a Main Belt Comet [PDF]

, 2015
Main Belt Comets (MBCs) are a newly identified class of solar system object, having asteroid-like orbits but sometimes exhibiting comet-like behavior.

Europe's future exploration of Main Belt Comets [PDF]

, 2018
We discuss possible European missions to explore the recently identified population of "main belt comets", which are small bodies with some asteroid-like properties and some comet-like ones.

Asteroids, Comets and the Water on Earth - A European Mission to the Main Belt Comets

, 2012
Main Belt Comets (MBCs) are a newly found population in the main asteroid belt. A spacecraft mission to MBCs can provide key insights into the formation and evolution of the planetary system and the early evolution of Earth.

Comet taxonomies: composition-based classifications and a search for comets in the Main Belt

Comets are icy small bodies assumed to have remained mostly unaltered since their formation, making them key tracers of the early stages of the Solar System. While comets show a great diversity of dynamical, physical and chemical properties, efforts have

Orbital Alignment of Main-belt Comets [PDF]

The Astronomical Journal, 2018
Abstract We examine the orbital element distribution of main-belt comets (MBCs), which are objects that exhibit cometary activity yet orbit in the main asteroid belt and may be potentially useful as tracers of ice in the inner solar system.

THE NUCLEUS OF MAIN-BELT COMET 259P/GARRADD [PDF]

The Astrophysical Journal, 2012
We present observations of the main-belt comet 259P/Garradd, previously known as P/2008 R1 (Garradd), obtained in 2011 and 2012 using the Gemini North Telescope on Mauna Kea in Hawaii, and the SOAR Telescope at Cerro Pachon in Chile, with the goal of computing the object's phase function and nucleus size. We find an absolute magnitude of $H_R=19.71\pm0.
