Abstract:
We used VLT/VIMOS images in the V band to obtain light curves of
extrasolar planetary transits OGLE-TR-111 and OGLE-TR-113, and
candidate planetary transits: OGLE-TR-82, OGLE-TR-86, OGLE-TR-91,
OGLE-TR-106, OGLE-TR-109, OGLE-TR-110, OGLE-TR-159, OGLE-TR-167,
OGLE-TR-170, OGLE-TR-171. Using difference imaging photometry, we were
able to achieve millimagnitude errors in the individual data points.
We present the analysis of the data and the light curves, by measuring
transit amplitudes and ephemerides, and by calculating geometrical
parameters for some of the systems. We observed 9 OGLE objects at the
predicted transit moments. Two other transits were shifted in time by
a few hours. For another seven objects we expected to observe transits
during the VIMOS run, but they were not detected. The stars
OGLE-TR-111 and OGLE-TR-113 are probably the only OGLE objects in the
observed sample to host planets, with the other objects being very
likely eclipsing binaries or multiple systems. In this paper we also
report on four new transiting candidates which we have found in the
data.
