The science case for a far-infrared interferometer in the era of JWST and ALMA
David Leisawitz, Matteo Bonato, Duncan Farrah +15
A space-based far-infrared interferometer could work synergistically with the James Webb Space Telescope (JWST) and the Atacama Large Millimeter Array (ALMA) to revolutionize our u…
Determining the Shape, Size, and Sources of the Zodiacal Dust Cloud using Polarized Ultraviolet Scattered Sunlight
Geoffrey Bryden, Neal J. Turner, Petr Pokorny +7
The solar system's Zodiacal Cloud is visible to the unaided eye, yet the origin of its constituent dust particles is not well understood, with a wide range of proposed divisions be…
A Deep and Wide Twilight Survey for Asteroids Interior to Earth and Venus
Scott S. Sheppard, David Tholen, Petr Pokorny +17
We are conducting a survey using twilight time on the Dark Energy Camera with the Blanco 4m telescope in Chile to look for objects interior to Earth's and Venus' orbits. To date we…
Exogenous delivery of water to Mercury
Kateryna Frantseva, David Nesvorný, Michael Mueller +3
Radar and spacecraft observations show the permanently shadowed regions around Mercury's North Pole to contain water ice and complex organic material. One possible source of this m…
Modeling Meteoroid Impacts on the Juno spacecraft
Petr Pokorný, Jamey R. Szalay, Mihály Horányi +1
Events which meet certain criteria from star tracker images onboard the Juno spacecraft have been proposed to be due to interplanetary dust particle impacts on its solar arrays. Th…
Collisional Evolution of the Inner Zodiacal Cloud
J. R. Szalay, P. Pokorny, D. M. Malaspina +9
The zodiacal cloud is one of the largest structures in the solar system and strongly governed by meteoroid collisions near the Sun. Collisional erosion occurs throughout the zodiac…
A Deep Search for Stable Venus Co-Orbital Asteroids: Limits on The Population
Petr Pokorny, Marc J. Kuchner, Scott S. Sheppard
A stable population of objects co-orbiting with Venus was recently hypothesized in order to explain the existence of Venus's co-orbital dust ring. We conducted a 5 day twilight sur…
Precision measurements of radar transverse scattering speeds from meteor phase characteristics
Michael Mazur, Petr Pokorny, Peter Brown +5
We describe an improved technique for using the backscattered phase from meteor radar echo measurements just prior to the specular point () to calculate meteor speeds and th…
Meteoroid Bombardment of Lunar Poles
Petr Pokorny, Menelaos Sarantos, Diego Janches +1
While the floors of deep lunar craters are largely shielded from solar radiation and thus provide an ideal thermal environment for water ice accumulation, meteoroids on highly incl…
Micrometeoroid Events in LISA Pathfinder
James Ira Thorpe, Jacob Slutsky, John Baker +104
The zodiacal dust complex, a population of dust and small particles that pervades the Solar System, provides important insight into the formation and dynamics of planets, comets, a…
A comprehensive model of the meteoroid environment around Mercury
Petr Pokorny, Menelaos Sarantos, Diego Janches
To characterize the meteoroid environment around Mercury and its contribution to the planet's exosphere, we combined four distinctive sources of meteoroids in the solar system: mai…
Measuring the meteoroid environments of the planets with meteor detectors on Earth
Paul Wiegert, Peter Brown, Petr Pokorny +2
We describe how meteors recorded at the Earth can be used to partly reconstruct the meteoroid environments of the planets if a large sample (i.e. millions of orbits at a minimum) i…
A reproducible method to determine the meteoroid mass index
Petr Pokorny, Peter G. Brown
Context. The determination of meteoroid mass indices is central to flux measurements and evolutionary studies of meteoroid populations. However, different authors use different app…
On the age and formation mechanism of the core of the Quadrantid meteoroid stream
Abedin Abedin, Pavel Spurny, Paul Wiegert +3
The Quadrantid meteor shower is among the strongest annual meteor showers, and has drawn the attention of scientists for several decades. The stream is unusual, among others, for s…
Dynamical Model for the Zodiacal Cloud and Sporadic Meteors
David Nesvorny, Diego Janches, David Vokrouhlicky +3
The solar system is dusty, and would become dustier over time as asteroids collide and comets disintegrate, except that small debris particles in interplanetary space do not last l…
Dynamics of Dust Particles Released from Oort Cloud Comets and Their Contribution to Radar Meteors
David Nesvorny, David Vokrouhlicky, Petr Pokorny +1
The Oort Cloud Comets (OCCs), exemplified by the Great Comet of 1997 (Hale-Bopp), are occasional visitors from the heatless periphery of the solar system. Previous works hypothesiz…
