Query: Investigating the physical properties of transiting hot Jupiters with
  the 1.5-m Kuiper Telescope   We present new photometric data of 11 hot Jupiter transiting exoplanets
(CoRoT-12b, HAT-P-5b, HAT-P-12b, HAT-P-33b, HAT-P-37b, WASP-2b, WASP-24b,
WASP-60b, WASP-80b, WASP-103b, XO-3b) in order to update their planetary
parameters and to constrain information about their atmospheres. These
observations of CoRoT-12b, HAT-P-37b and WASP-60b are the first follow-up data
since their discovery. Additionally, the first near-UV transits of WASP-80b and
WASP-103b are presented. We compare the results of our analysis with previous
work to search for transit timing variations (TTVs) and a wavelength dependence
in the transit depth. TTVs may be evidence of a third body in the system and
variations in planetary radius with wavelength can help constrain the
properties of the exoplanet's atmosphere. For WASP-103b and XO-3b, we find a
possible variation in the transit depths that may be evidence of scattering in
their atmospheres. The B-band transit depth of HAT-P-37b is found to be smaller
than its near-IR transit depth and such a variation may indicate TiO/VO
absorption. These variations are detected from 2-4.6$\sigma$, so follow-up
observations are needed to confirm these results. Additionally, a flat spectrum
across optical wavelengths is found for 5 of the planets (HAT-P-5b, HAT-P-12b,
WASP-2b, WASP-24b, WASP-80b), suggestive that clouds may be present in their
atmospheres. We calculate a refined orbital period and ephemeris for all the
targets, which will help with future observations. No TTVs are seen in our
analysis with the exception of WASP-80b and follow-up observations are needed
to confirm this possible detection.
