Multicolour time series photometry of 2MASS 1207-3932.


Abstract (from CDS):

Time series photometry in VRI of the young brown dwarf Two-Micron All-Sky Survey (2MASS) J1207334-393254 is presented. Variability in I is insignificant, but amplitudes up to ∼0.2 mag in R, and ∼0.55 mag in V, are seen within a single night. There is also microvariability on time-scales of an hour or so, which appears to be present in data from all the three filters. There may be a non-sinusoidal periodicity of about half a day in the V and R data. A likely explanation for the variability is the presence of accretion hot spots.
