Size and Shape Constraints of (486958) Arrokoth from Stellar Occultations

Marc W. Buie, Simon B. Porter, Peter Tamblyn +130

We present the results from four stellar occultations by (486958) Arrokoth, the flyby target of the New Horizons extended mission. Three of the four efforts led to positive detecti…

Time variability in the bipolar scattered light nebula of L1527 IRS: A possible warped inner disk

Brian T. Cook, John J. Tobin, Michael F. Skrutskie +1

Context. The bipolar outflows associated with low-mass protostars create cavities in the infalling envelope. These cavities are illuminated by the central protostar and inner disk,…

Ultra-Stable Environment Control for the NEID Spectrometer: Design and Performance Demonstration

Paul Robertson, Tyler Anderson, Gudmundur Stefansson +30

Two key areas of emphasis in contemporary experimental exoplanet science are the detailed characterization of transiting terrestrial planets, and the search for Earth analog planet…

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…
