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…
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…
CO-Driven Activity in Comet C/2017 K2 (PANSTARRS)
Karen J. Meech, Jan T. Kleyna, Olivier Hainaut +12
Comet C/2017 K2 (PANSTARRS) was discovered by the Pan-STARRS1 (PS1) Survey on 2017 May 21 at a distance 16.09 au from the Sun, the second most distant discovery of an active comet.…
A dwarf planet class object in the 21:5 resonance with Neptune
Matthew J. Holman, Matthew J. Payne, Wesley Fraser +33
We report the discovery of a dwarf planet candidate by the Pan-STARRS Outer Solar System Survey. 2010 JO is red with , roughly round,…
The splitting of double-component active asteroid P/2016 J1 (PANSTARRS)
Fernando Moreno, Francisco Pozuelos, Bojan Novakovic +20
We present deep imaging observations, orbital dynamics, and dust tail model analyses of the double-component asteroid P/2016 J1 (J1-A and J1-B). The observations were acquired at t…
Distant Solar System Objects identified in the Pan-STARRS1 survey
R. J. Weryk, E. Lilly, S. Chastel +9
We present a method to identify distant solar system objects in long-term wide-field asteroid survey data, and conduct a search for them in the Pan-STARRS1 (PS1) image data acquire…
