A Versatile Technique to Enable sub-milli-Kelvin Instrument Stability for Precise Radial Velocity Measurements: Tests with the Habitable-zone Planet Finder
Gudmundur Stefansson, Frederick Hearty, Paul Robertson +13
Insufficient instrument thermo-mechanical stability is one of the many roadblocks for achieving 10cm/s Doppler radial velocity (RV) precision, the precision needed to detect Earth-…
iLocater: A Diffraction-limited Doppler Spectrometer for the Large Binocular Telescope
Justin R. Crepp, Jonathan Crass, David King +31
We are developing a stable and precise spectrograph for the Large Binocular Telescope (LBT) named "iLocater." The instrument comprises three principal components: a cross-dispersed…
The iLocater cryostat: design and thermal control strategy for precision radial velocity measurements
Jonathan Crass, Louis G. Fantano, Frederick R. Hearty +8
The current generation of precision radial velocity (RV) spectrographs are seeing-limited instruments. In order to achieve high spectral resolution on 8m class telescopes, these sp…
