Description
We present the results of a deep, wide-field transit survey targeting
"Hot Jupiter" planets in the Lupus region of the Galactic plane
conducted over 53 nights concentrated in two epochs separated by a year.
Using the Australian National University 40-inch telescope at Siding
Spring Observatory (SSO), the survey covered a 0.66 deg2
region close to the Galactic plane (b = 11°) and monitored a total
of 110,372 stars (15.0 <= V <= 22.0). Using difference imaging
photometry, 16,134 light curves with a photometric precision of σ
< 0.025 mag were obtained. These light curves were searched for
transits, and four candidates were detected that displayed low-amplitude
variability consistent with a transiting giant planet. Further
investigations, including spectral typing and radial velocity
measurements for some candidates, revealed that of the four, one is a
true planetary companion (Lupus-TR-3), two are blended systems
(Lupus-TR-1 and 4), and one is a binary (Lupus-TR-2). The results of
this successful survey are instructive for optimizing the observational
strategy and follow-up procedure for deep searches for transiting
planets, including an upcoming survey using the SkyMapper telescope at
SSO.

The principal objectives of this project are: 1) to study the structure and dynamics of the solar interior, 2) to extend this study to other stars, 3) to search for extrasolar planets using photometric methods (primarily by transits of their host stars) and their characterization (using radial velocity information) and 4) the study of the planetary
