Preview of Comet C/2021 A1 (Leonard) and Its Encounter with Venus
Qicheng Zhang, Quanzhi Ye, Shreyas Vissapragada +2
Long period comet C/2021 A1 (Leonard) will approach Venus to within 0.029 au on 2021 December 18 and may subsequently graze the planet with its dust trail less than two days later.…
Disintegration of Long-Period Comet C/2019 Y4 (ATLAS): I. Hubble Space Telescope Observations
Quanzhi Ye, David Jewitt, Man-To Hui +8
Near-Sun Comet C/2019 Y4 (ATLAS) is the first member of a long-period comet group observed to disintegrate well before perihelion. Here we present our investigation into this disin…
Multi-Epoch VLBI of L Dwarf Binary 2MASS J0746+2000AB: Precise Mass Measurements and Confirmation of Radio Emission from Both Components
Qicheng Zhang, Gregg Hallinan, Walter Brisken +2
Surveys have shown that up to one tenth of all ultracool dwarfs (UCDs) are appreciable radio emitters, with their emission attributed to a combination of gyrosynchrotron radiation…
Orbital Deflection of Comets by Directed Energy
Qicheng Zhang, Philip M. Lubin, Gary B. Hughes
Cometary impacts pose a long-term hazard to life on Earth. Impact mitigation techniques have been studied extensively, but they tend to focus on asteroid diversion. Typical asteroi…
Prospects for Backtracing 1I/`Oumuamua and Future Interstellar Objects
Qicheng Zhang
1I/`Oumuamua is the first of likely many small bodies of extrasolar origin to be found in the solar system. These interstellar objects (ISOs) are hypothesized to have formed in ext…
1I/2017 U1 (`Oumuamua) is Hot: Imaging, Spectroscopy and Search of Meteor Activity
Quan-Zhi Ye, Qicheng Zhang, Michael S. P. Kelley +1
1I/2017 U1 (`Oumuamua), a recently discovered asteroid in a hyperbolic orbit, is likely the first macroscopic object of extrasolar origin identified in the solar system. Here, we p…
