Descripción
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.
