The Dynamical Origin of Millimetre-Sized Sporadic Meteoroids
Tam Do, Peter Brown, Petr Pokorný
Determining the relative contributions of cometary and asteroidal sources to the sporadic meteoroid population remains a longstanding challenge, particularly because commonly used…
Erosion of volatiles by micro-meteoroid bombardment on Ceres, and comparison to the Moon and Mercury
Petr Pokorný, Erwan Mazarico, Norbert Schorghofer
(1) Ceres, the largest reservoir of water in the main-belt, was recently visited by the Dawn spacecraft that revealed several areas bearing HO-ice features. Independent telesco…
Supercatastrophic disruption of asteroids in the context of SOHO comet, fireball and meteor observations
Paul Wiegert, Peter Brown, Petr Pokorný +5
Granvik et al. (2016) report an absence of asteroids on orbits with perihelia near the Sun that they attribute to the 'supercatastrophic disruption' of these bodies. Here we invest…
The Near-Sun Dust Environment: Initial Observations from Parker Solar Probe
J. R. Szalay, P. Pokorný, S. D. Bale +11
The Parker Solar Probe (PSP) spacecraft has flown into the most dense and previously unexplored region of our solar system's zodiacal cloud. While PSP does not have a dedicated dus…
Co-orbital Asteroids as the Source of Venus's Zodiacal Dust Ring
Petr Pokorný, Marc J. Kuchner
Photometry from the Helios and STEREO spacecraft revealed regions of enhanced sky surface-brightness suggesting a narrow circumsolar ring of dust associated with Venus's orbit. We…
Reconciling the dawn-dusk asymmetry in Mercury's exosphere with the micrometeoroid impact directionality
Petr Pokorný, Menelaos Sarantos, Diego Janches
Combining dynamical models of dust from Jupiter Family Comets and Halley-type Comets, we demonstrate that the seasonal variation of the dust/meteoroid environment at Mercury is res…
Dormant Comets Among the Near-Earth Object Population: A Meteor-Based Survey
Quan-Zhi Ye, Peter G. Brown, Petr Pokorný
Dormant comets in the near-Earth object (NEO) population are thought to be involved in the terrestrial accretion of water and organic materials. Identification of dormant comets is…
When Comets Get Old: A Synthesis of Comet and Meteor Observations of the Low Activity Comet 209P/LINEAR
Quan-Zhi Ye, Man-To Hui, Peter G. Brown +4
It is speculated that some weakly active comets may be transitional objects between active and dormant comets. These objects are at a unique stage of the evolution of cometary nucl…
