The Planetary Science JournalAs the Centaurs of the outer solar system have become better studied, their relationship with the Jupiter-family comets (JFCs) and their connection to the primordial protoplanetary disk have come under deeper scrutiny: which properties of the comets ...

Active Asteroids: Main-Belt Comets and Disrupted Asteroids [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractThe study of active asteroids has attracted a great deal of interest in recent years since the recognition of main-belt comets (which orbit in the main asteroid belt, but exhibit comet-like activity due to the sublimation of volatile ices) as a new class of comets in 2006, and the discovery of the first disrupted asteroids (which, unlike MBCs ...

Main-belt comets as contributors to the near-Earth objects population
Aims. Most studies of the dynamics of main-belt objects describing the evolution of the bodies in inner Solar System have been carried with models that include weak nongravitational forces, such as the Yarkovsky and YORP effects.

3 μm Phase Curves of Main-belt Asteroids from NEOWISE Photometry
The Planetary Science JournalThe shapes of asteroid phase curves are influenced by the physical properties of asteroid surfaces. The variation of an asteroid’s brightness as a function of the solar phase angle can tell us about surface properties such as grain size distribution ...

The Trajectory of 3I/ATLAS Through the Inner Solar System: Close Encounters and Possible Collisions
The Astronomical Journal3I/ATLAS is the third interstellar object (ISO) identified to date. Unlike other known ISOs, 3I/ATLAS travels on a nearly ecliptic, retrograde orbit ( i ≈ 175°).

Modeling and Analysis of Main-belt Asteroidal Dust Flux and Velocity Distribution at Inner Planets
The Astrophysical JournalInterplanetary dust in the inner solar system originates from multiple sources, including short-period comets and main-belt asteroids. In this work, we focus specifically on the dynamical evolution of asteroid-derived dust using N -body simulations that ...

The Dynamical Origins of the Dark Comets and a Proposed Evolutionary Track [PDF]
So-called \u27dark comets\u27 are small, morphologically inactive near-Earth objects (NEOs) that exhibit nongravitational accelerations inconsistent with radiative effects. These objects exhibit short rotational periods (minutes to hours), where measured.
