The Palomar Transient Factory (PTF) is a new survey for astronomical transients being undertaken with the wide-field CCD array recently installed on the Palomar 48" telescope. The camera consists of a 12-CCD array, each 2048 by 4096 pixels, giving a total nominal 7.8 square degree array with 1 arcsec pixels. The Orion project is an experiment that during its first year is focusing on a single pointing in the Orion star-forming region as part of the PTF survey. The project has been assigned 40 consecutive nights per year for three years to perform intensive time-series observations with the aim of detecting close-in, Jupiter-sized planets transiting young stars. Little is known about the distribution and frequency of planets around stars that are 1-100 Myr old - the time frame in which the giant planets are expected to form. Our principal goal is to investigate the frequency of planets around stars at young ages. In addition, the observations will provide a unique dataset to study a variety of stellar astrophysics, including eclipsing binary systems for testing star formation and evolution models; characterising stellar activity and rotational periods; and characterising previously unknown young stars in the Orion region. Here we present preliminary results from the first science data.
