A search for extrasolar planetary transits using the extended Kepler mission
(K2) campaigns 9 and 11 revealed five new candidates towards the Galactic
bulge. The stars EPIC 224439122, 224560837, 227560005, 230778501 and 231635524
are found to have low amplitude transits consistent with extrasolar planets,
with periods P = 35.1695, 3.6390, 12.4224, 17.9856, and 5.8824 days,
respectively. The K2 data and existing optical photometry are combined with the
multi-band near-IR photometry of the VVV survey and 2MASS in order to measure
accurate physical parameters for the host stars. We then measure the radii of
the new planet candidates from the K2 transit light curves and also estimate
their masses using mass-radius relations, concluding that two of these
candidates could be low mass planets, and three could be giant gaseous planets.
