Ushering in high angular resolution observatories in the far-infrared: The case for a double-Fourier interferometer
C. S. Benson, M. Bonato, T. A. Davis +14
A far-infrared (far-IR) interferometer from a space-based platform would bring about a transformational improvement in the spatial detail of astronomical observations that are inac…
Modeling the meteoroid environment far from the ecliptic plane
Althea V. Moorhead, Petr Pokorný, Marcus A. Holden +1
We describe a new version (numbered 3.1) of NASA's Meteoroid Engineering Model (MEM) in which we extend the model to handle locations that lie more than a few degrees in latitude o…
Colors and Dynamics of a Near-Sun Orbital Asteroid Family: 2021 PH27 and 2025 GN1
Scott Sheppard, Henry Hsieh, Petr Pokorny +6
We observed the dynamically similar near-Sun asteroids 2021 PH27 and 2025 GN1 for their optical colors. These objects have the lowest known semi-major axes of any asteroids. 2021 P…
How long-lived grains dominate the shape of the Zodiacal Cloud
Petr Pokorny, Althea V. Moorhead, Marc J. Kuchner +2
Grain-grain collisions shape the 3-dimensional size and velocity distribution of the inner Zodiacal Cloud and the impact rates of dust on inner planets, yet they remain the least u…
