Abstract

We have developed Fabry-Perot and Michelson based Interferometric Stellar Oscillation Spectrometers (FP-ISOS and Michelson-ISOS) to measure radial velocity curves of ultra-short period variable stars and to search for solar-type stellar oscillations. Both instruments are intrinsically stable at the 1 ms 1 level and with Michelson-ISOS we have achieved a photon shot noise limited sensitivity of better than 1 ms 1 on bright stars.
