The Main Belt Comets and Ice in the Solar System [PDF]

Astronomy and Astrophysics Review, 2017
We review the evidence for buried ice in the asteroid belt; specifically the questions around the so-called Main Belt Comets (MBCs). We summarise the evidence for water throughout the Solar System, and describe the various methods for detecting it ...

The Main-Belt Comets: The Pan-STARRS1 Perspective [PDF]

Icarus, 2015
We analyze a set of 760 475 observations of 333 026 unique main-belt objects obtained by the Pan-STARRS1(PS1) survey telescope between 2012 May 20 and 2013 November 9, a period during which PS1 discoveredtwo main-belt comets, P/2012 T1 (PANSTARRS) and P ...

A Binary Main-Belt Comet [PDF]

Nature, 2017
The asteroids are primitive solar system bodies which evolve both collisionally and through disruptions due to rapid rotation [1]. These processes can lead to the formation of binary asteroids [2-4] and to the release of dust [5], both directly and, in some cases, through uncovering frozen volatiles.

Main Belt Comets: A New Class of Small Bodies in the Solar System

Planetary and Space Science, 2011
Comets and asteroids have traditionally been considered two distinct separate populations of small bodies in the solar system, according to their different dynamical, observational, and compositional characteristics.

Measuring The Mass of A Main Belt Comet: Proteus Mission

2019 IEEE 5th International Workshop on Metrology for AeroSpace (MetroAeroSpace), 2019
To accurately estimate the mass of a comet, is a challenging task, given the complexity of its dynamical environment, and particularly so while close to perihelion, where the coma emissions are stronger. This study describes an operational approach for simultaneous orbit determination and mass estimation of a cometary target, using detailed dynamical ...

Re-activation of main-belt comet 288P in 2021

2022
<p>The binary main-belt comet 288P is peculiar both because of its comet-like activity and because of its unusual system properties, combining near-equal component sizes with a wide separation of about 100 times the primary radius. The system likely formed by rotational disruption after YORP spin-up and subsequently widened, possibly by ...
