Scientific paper

TEDI (the TripleSpec Externally Dispersed Interferometer) is a new radial velocity instrument at Palomar designed to detect planets orbiting low-mass stars in the near infrared. By passing starlight first through an interferometer, an unresolved comb is superimposed on the stellar spectrum. Analysis of the resulting Moire patterns allows for high velocity precision despite the moderate spectral resolution of the TripleSpec spectrograph (R ˜ 2700 in J,H,K bands simultaneously).
