Sodium Brightening of (3200) Phaethon Near Perihelion
Qicheng Zhang, Karl Battams, Quanzhi Ye +2
Sunskirting asteroid (3200) Phaethon has been repeatedly observed in STEREO HI1 imagery to anomalously brighten and produce an antisunward tail for a few days near each perihelion…
Dust Evolution in the Coma of Distant, Inbound Comet C/2017 K2 (PANSTARRS)
Qicheng Zhang, Ludmilla Kolokolova, Quanzhi Ye +1
C/2017 K2 (PANSTARRS) is an Oort cloud comet previously observed to be active at heliocentric distances r>20 au on what is likely its first passage through the inner solar system.…
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…
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…
