cds-question@unistra.frasteroidsinfrared-photometryvisible-astronomyphotometryWe initiated the bilateral collaboration between the Lulin Observatory and the Purple Mountain Observatory to collect asteroid lightcurves using the Chinese Near-Earth Object Survey Telescope at the Xuyi Observation Station. The primary goal of this collaboration was to discover super-fast rotators (SFRs) and study their physical properties. Two campaigns have been conducted: (a) a survey of ~45{deg}^2^ using 8minute cadence during 2017 February 26-March 2, and (b) a survey of ~60{deg}^2^ using 10minute cadence during 2018 March 9-12. Our samples are mainly main-belt asteroids and some Hildas and Jupiter Trojans. Out of 4522 collected lightcurves, 506 reliable rotation periods were obtained. Among the reliable rotation periods, we found 16 candidates with a possible rotation period of <2.2hr, in which (134291) 2006 DZ6 shows a very convincing folded lightcurve and the other 15 candidates only have a likely trend. Further confirmation is needed for the rotation periods of these SFR candidates. In addition, (2280) Kunikov seems to have an eclipsing feature on its lightcurve with a relatively long rotation period suggesting that it is likely a fully synchronized binary asteroid. When the preliminary spin-rate distributions were carried out for asteroids using different sizes, no obvious difference was found.2020AJ....160...73Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/160/73CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/astorb : Orbits of Minor Planets (Bowell+ 2014)J/A+A/527/A42 : Photometry of asteroid (21) Lutetia (de Leon+, 2011)J/A+A/546/A86 : R absolute magnitudes of Kuiper Belt objects (Peixinho+, 2012)J/A+A/556/A8 : 100 asteroids rotational parameters (Lhotka+, 2013)J/A+A/561/A45 : Asteroid (341843) 2008 EV5 WISE light curves (Ali-Lagoa+, 2014)J/A+A/562/A48 : Light curves of asteroid (25143) Itokawa (Lowry+, 2014)J/ApJ/793/50 : Observed light curve of (3200) Phaethon (Ansdell+, 2014)J/ApJS/219/27 : Surveys of asteroid rotation periods using iPTF (Chang+, 2015)J/ApJS/227/20 : Rotation periods of asteroids using iPTF (Chang+, 2016)J/A+A/617/A12 : Taxonomic classification of asteroids (Popescu+, 2018)J/A+A/627/A172 : Near-Earth asteroid (1917) Cuyo opt. & IR obs.
