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…
A comprehensive radial velocity error budget for next generation Doppler spectrometers
Samuel Halverson, Ryan Terrien, Suvrath Mahadevan +14
We describe a detailed radial velocity error budget for the NASA-NSF Extreme Precision Doppler Spectrometer instrument concept NEID (NN-explore Exoplanet Investigations with Dopple…
Cosmic variance in [O/Fe] in the Galactic disk
S. Bertran de Lis, C. Allende Prieto, S. R. Majewski +11
We examine the distribution of the [O/Fe] abundance ratio in stars across the Galactic disk using H-band spectra from the Apache Point Galactic Evolution Experiment (APOGEE). We mi…
Companions to APOGEE Stars I: A Milky Way-Spanning Catalog of Stellar and Substellar Companion Candidates and their Diverse Hosts
Nicholas W. Troup, David L. Nidever, Nathan De Lee +24
In its three years of operation, the Sloan Digital Sky Survey (SDSS-III) Apache Point Observatory Galactic Evolution Experiment (APOGEE-1) observed 14,000 stars with enough epoc…
