ICand RCband time-series observations of some bright ultracool dwarfs.

KOEN C.

Abstract (from CDS):

The results of more than 100 h of CCD photometric monitoring of 10 L dwarfs and two T dwarfs are presented. Reasonable evidence is shown for ICband variability in DENIS 0255-4700, DENIS 1705-0516 and 2M 2104-1037. Substantial brightening of the T dwarf binary ε Indi Bab was observed over the course of 3.6 h; it is unlikely that this could have been caused by surface spots. No unequivocal variability could be detected in the RCband.
