Theoretical predictions of solar-like oscillations in cool Delta Scuti stars motivated us to organize a spectroscopic observing campaign of the metal-rich star Rho Puppis. High precision radial velocity measurements obtained in 2008 through an iodine cell attached to UCLES at the Anglo Australian Telescope (extracted with the code iSONG) as well as high resolution spectra observed with CORALIE at the Swiss 1.2-m Leonard Euler telescope, are the basis material for detecting the solar-like pulsation. Furthermore we have 30 days of photometry observed with the MOST satellite, which led to the detection of at least two additional frequencies attributed to nonradial modes. Further intrinsic signals cannot be excluded. In this poster paper we present preliminary results.
