Query: The disk of 2MASS 15491331-3539118 = GQ Lup C as seen by HST and WISE   Very recently, a second companion on wider orbit has been discovered around
GQ Lup. This is a low-mass accreting star partially obscured by a disk seen at
high inclination. If detected, this disk may be compared to the known disk
around the primary. We detected this disk on archive HST and WISE data. The
extended spectral energy distribution provided by these data confirms the
presence of accretion from Halpha emission and UV excess, and shows an IR
excess attributable to a warm disk. In addition, we resolved the disk on the
HST images. This is found to be roughly aligned with the disk of the primary.
Both of them are roughly aligned with the Lupus I dust filament containing GQ
Lup.
