A Sextet of Main-belt Binary Asteroid Candidates
Abstract
Analysis of CCD photometry observations at the Center for Solar System Studies-Palmer Divide Station (CS3- PDS) made in 2014 June-October found six main-belt binary candidates. 1355 Magoeba (Hungaria) is a possible binary, showing indications of a secondary period. 2131 Mayall is a known binary. The rotation period of the primary was confirmed. (15778) 1993 NH is a possible member of the subclass of wide binaries that are characterized by a large amplitude, long period lightcurve superimposed by a low amplitude, short period component. (18890) 2000 EV26 is a confirmed new binary, showing mutual events in the satellite’s lightcurve. Analysis of data from 2011 shows, at best, only weak evidence of the satellite. (27568) 2000 PT6 is a probable binary with strong evidence of a second period but no confirming mutual events. (30535) 2001 OR5 is a possible binary that shows a secondary period but it may be a harmonic artifact of Fourier analysis.
