Quadratic shift-and-stack for Ground-Based Optical Detection of Faint Cislunar Objects
Qi Li, Yuhui Zhao, Chengxing Zhai +2
Detecting faint objects in cislunar space using ground-based optical telescopes is difficult because of their low brightness, strong lunar background, and complex, nonlinear appare…
Near-Earth Object Observations using Synthetic Tracking
Chengxing Zhai, Michael Shao, Navtej Saini +5
Synthetic tracking (ST) has emerged as a potent technique for observing fast-moving near-Earth objects (NEOs), offering enhanced detection sensitivity and astrometric accuracy by a…
Micro-arcsecond Astrometry Technology: Detector and Field Distortion Calibration
Michael Shao, Chengxing Zhai, Bijan Nemati +3
Microarcsecond (uas) astrometry is an indispensable technique to detect earth-like exoplanets, fully characterize exoplanetary orbits, and measure their masses --information critic…
The discovery and characterization of a kilometre sized asteroid inside the orbit of Venus
Bryce T. Bolin, T. Ahumada, P. van Dokkum +8
Near-Earth asteroid population models predict the existence of bodies located inside the orbit of Venus. Despite searches up to the end of 2019, none had been found. We report disc…
Time-series and Phasecurve Photometry of Episodically-Active Asteroid (6478) Gault in a Quiescent State Using APO, GROWTH, P200 and ZTF
Josiah N. Purdum, Zhong-Yi Lin, Bryce T. Bolin +49
We observed Episodically Active Asteroid (6478) Gault in 2020 with multiple telescopes in Asia and North America and have found that it is no longer active after its recent outburs…
Characterization of Temporarily-Captured Minimoon 2020 CD by Keck Time-resolved Spectrophotometry
Bryce T. Bolin, Christoffer Fremling, Timothy R. Holt +42
We present time-resolved visible spectrophotometry of minimoon 2020 CD, the second asteroid known to become temporarily captured by the Earth-Moon system's gravitational field.…
