  We report the discovery of the resolved disk around HD 131835 and present the
analysis and modeling of its thermal emission. HD 131835 is a ~15 Myr A2 star
in the Scorpius-Centaurus OB association at a distance of 122.7 +16.2 -12.8
parsec. The extended disk has been detected to ~1.5" (200 AU) at 11.7 {\mu}m
and 18.3 {\mu}m with T-ReCS on Gemini South. The disk is inclined at an angle
of ~75{\deg} with the position angle of ~61{\deg}. The flux of HD 131835 system
is 49.3+-7.6 mJy and 84+-45 mJy at 11.7 {\mu}m and 18.3 {\mu}m respectively. A
model with three grain populations gives a satisfactory fit to both the
spectral energy distribution and the images simultaneously. This best-fit model
is composed of a hot continuous power-law disk and two rings. We characterized
the grain temperature profile and found that the grains in all three
populations are emitting at temperatures higher than blackbodies. In
particular, the grains in the continuous disk are unusually warm; even when
considering small graphite particles as the composition.
