Therefore, the Hough transform, a line detecting algorithm, can be used to connect the line-up detections to find asteroids. We applied this algorithm to a high-cadence Pan-STARRS 1 (PS1) observation, which was originally designed to collect asteroid light curves for rotation period measurements. The algorithm recovered most of the known asteroids in the observing fields and, moreover, discovered 3574 new asteroids with magnitude mainly of 21.5<w_p1_<22.5mag. This magnitude range is equivalent to subkilometer main-belt asteroids (MBAs), which usually lack rotation period measurements due to their faintness. Using the light curves of the 3574 new asteroids, we obtained 122 reliable rotation periods, of which 13 are super-fast rotators (SRFs; i.e., rotation period of <2hr). The required cohesion to survive these SFRs range from tens to thousands of Pa, a value consistent with the known SFRs and the regolith on the Moon and Mars. The higher chance of discovering SFRs here suggests that subkilometer MBAs probably harbor more SFRs.2020AJ....159...25Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/159/25CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/349 : The Pan-STARRS release 1 (PS1) Survey - DR1 (Chambers+, 2016)J/A+A/508/1503 : Photometry of 3 main belt asteroids (Marciniak+, 2009)J/A+A/529/A107 : Photometry of 4 main belt asteroids (Marciniak+, 2011)J/A+A/545/A131 : Photometry of 8 main belt asteroids (Marciniak+, 2012)J/ApJ/759/L8 : WISE/NEOWISE observations main belt asteroids (Masiero+, 2012)J/ApJ/770/7 : WISE/NEOWISE Main Belt asteroids family member (Masiero+,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/AJ/150/75 : Asteroid light curves from PTF survey (Waszczak+, 2015)J/ApJ/814/65 : Jupiter HST light curves (Karalidi+, 2015)J/ApJS/219/27 : Surveys of asteroid rotation periods using iPTF (Chang+, 2015)J/A+A/596/A40 : Main-belt asteroids optical light curves (Szabo+, 2016)J/AJ/152/54 : Spectroscopy main-belt Ch/Cgh-type asteroids (Vernazza+, 2016)J/ApJ/818/176 : HST/WFC3 NIR photometry of 2M1207b (Zhou+, 2016)J/ApJS/227/20 : Rotation periods of asteroids using iPTF (Chang+, 2016)J/ApJS/234/37 : R-band K2 photometry of main-belt asteroids (Molnar+, 2018)J/ApJS/237/19 : KMTNet LCs of ~1000 main-belt asteroids (Erasmus+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/159/25https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/159/25http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/159/25https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/159/25https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/159/25http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/159/25GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/159/25/table3 (Light curve data set)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/159/25/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/159/25/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/159/25/table3?GETtext/xml+votable180.050000true27.5874583312.641230560.005555555555555556Cone search capability for table J/AJ/159/25/table1 (Pan-STARRS 1 (PS1) observation in 2016 october)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/159/25/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/159/25/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/159/25/table1?GETtext/xml+votable180.050000true28.113.140.0055555555555555564/32 33 1143 5/46 136 137 138 140 141 146 4566 4567 6/171 174 175 188 190 191 556 557 558 568 569 578 608 640 18253 18255 18261 18262 18263 18277 18279 18384 18385 18388 18389https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/159/25?format=asciiOpticalInfrareddefaultJ/AJ/159/25/table2Information of the new asteroidsrecnoRecord number assigned by the VizieR team.
