  1. How “average” is Solar? Jade Bond 5th April 2009 Image: NASA/IPAC/R. Hurt

  2. Enriched Host Stars Host stars appear metal-rich, esp. Fe Similar trends in Mg, Si, C, O, Ti, Al, Na, Mn, Co, Ni, Sc, V, Cu, Zr and Nd • Host stars appear metal-rich, esp. Fe • Similar trends in Mg, Si, C, O, Ti, Al, Na, Mn, Co, Ni, Sc, V, Cu, Zr and Nd Santos et al. (2003)

  3. Terrestrial Implications? • Geology of these planets may be unlike anything we see in the Solar System • Implications for plate tectonics, interior structure, habitability, surface features, atmospheric compositions, detection . . .
