Asteroid Discovery and Light Curve Extraction Using the Hough Transform -- A Rotation Period Study for Sub-Kilometer Main-Belt Asteroids
Kai-Jie Lo, Chan-Kao Chang, Hsing-Wen Lin +8
The intra-night trajectories of asteroids can be approximated by straight lines, and so are their intra-night detections. Therefore, the Hough transform, a line detecting algorithm…
The Orbit and Size-Frequency Distribution of Long Period Comets Observed by Pan-STARRS1
Benjamin Boe, Robert Jedicke, Karen J. Meech +9
We introduce a new technique to estimate the comet nuclear size frequency distribution (SFD) that combines a cometary activity model with a survey simulation and apply it to 150 lo…
Searching for Super-Fast Rotators Using the Pan-STARRS 1
Chan-Kao Chang, Hsing-Wen Lin, Wing-Huen Ip +9
A class of asteroids, called large super-fast rotators (large SFRs), have rotation periods shorter than 2 hours and diameters larger than ~ 0.3 km. They pose challenges to the usua…
