The PTF Orion project is a part of the Palomar Transient Factory (PTF), a photometric survey for astronomical transients being undertaken with a dedicated wide-field CCD array 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 field of view with 1 arcsecond pixels. The Orion project is an experiment focusing on a single pointing in the Orion star-forming region as a part of this survey.
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 these young ages. In addition, the observations 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.
40 nights of data were dedicated to the Orion project in December 2009 and January 2010 to perform intensive time-series observations with the aim of detecting close-in, Jupiter-sized planets transiting young stars. We will present some of the results from these observations.
