Title: A Great Spot on a Kepler L Dwarf
Abstract:
We are using NASA's Kepler Mission to obtain an unprecedented two-
year photometric time series on a nearby L1 dwarf. We request MMT
optical spectra and KPNO near-infrared photometry taken simultaneously
with Kepler photometry to enable the physical interpretation of the
variability. Variations seen in other L dwarfs have been attributed to
clouds, flares, and (magnetic) starspots, but the interpretation remains
ambiguous due to limited time coverage and the lack of simultaneous
spectral data. Multiwavelength data can distinguish between magnetic
spots and dust clouds.
