A Catalogue of Interstellar Material Delivery From Nearby Debris Disks
Cole R. Gregg, Paul A. Wiegert
We modeled the trajectories of material ejected from 20 nearby debris disk stars, including Epsilon Eridani (Ran), Vega, Fomalhaut, and Beta Pictoris, within a simulated Milky Way…
A limit on the mass of the Taurid Resonant Swarm at sub-100 meter sizes
Paul Wiegert, Denis Vida, David L. Clark +3
We report on a pencil-beam survey of the Taurid Swarm, a possible concentration of bodies in the Taurid meteoroid stream associated with the 7:2 mean-motion resonance with Jupiter.…
The Potential Danger to Satellites due to Ejecta from a 2032 Lunar Impact by Asteroid 2024 YR4
Paul Wiegert, Peter Brown, Jack Lopes +1
On 2032 December 22 the 60 m diameter asteroid 2024 YR4 has a 4% chance of impacting the Moon. Such an impact would release 6.5 MT TNT equivalent energy and produce a ~1 km diamete…
An Upper Limit on the Interstellar Meteoroid Flux at Video Sizes from the Global Meteor Network
Paul Wiegert, Vanessa Tran, Cole Gregg +2
Material arriving at our solar system from the Galaxy may be detected at Earth in the form of meteors ablating in our atmosphere. Here we report on a search for interstellar meteor…
A Case Study of Interstellar Material Delivery: α Centauri
Cole R. Gregg, Paul A. Wiegert
Interstellar material has been discovered in our Solar System, yet its origins and details of its transport are unknown. Here we present Centauri as a case study of the deliver…
Telescope-to-Fireball Characterization of Earth Impactor 2022 WJ1
Theodore Kareta, Denis Vida, Marco Micheli +10
Comparing how an asteroid appears in space to its ablation behavior during atmospheric passage and finally to the properties of associated meteorites represents the ultimate probe…
