DESCRIPTION:More than two decades after the discovery of the first exoplan
 et with radial velocity (RV) measurements\, large quantities of data exist
  from dedicated planet-hunting spectrographs. These spectra play an import
 ant role not only in the discovery and characterization of planets but als
 o as a rich source of information about bright stars in the solar neighbor
 hood. I will summarize recent efforts to gain insight into the planet form
 ation process via extremely precise (0.01 dex) abundance measurements of s
 olar twin stars with and without planets. I will also discuss approaches t
 o the data analysis challenge of extracting maximally-precise RV measureme
 nts from these spectra in pursuit of Earth-like planets.\n\n
