Title: N2K: Detection of Short-Period Extrasolar Planets

Abstract: The N2K program is designed to screen metal-rich stars for the presence of short-period planets with \msini comparable to or greater than Saturn. In the past year, this program has detected 4 new short period planets and there are 35 excellent planet candidates showing curvature and 3-10 sigma scatter in radial velocities. All short period candidates are followed with photometry to search for transits and one planet, HD149026b, was observed to transit its host star with a 3 mmag transit depth (1/5 the transit depth of HD209458). This transit would have likely been missed by photometric surveys, emphasizing the key role that Doppler observations from the N2K program play in transit detections. We request time to continue this program in order to obtain 3 radial velocity measurements for a set of 120 new stars.
