EXPRES. II. Searching for Planets Around Active Stars: A Case Study of HD 101501
Samuel H. C. Cabot, Rachael M. Roettenbacher, Gregory W. Henry +7
By controlling instrumental errors to below 10 cm/s, the EXtreme PREcision Spectrograph (EXPRES) allows for a more insightful study of photospheric velocities that can mask weak Ke…
Lunar Exploration as a Probe of Ancient Venus
Samuel H. C. Cabot, Gregory Laughlin
An ancient Venusian rock could constrain that planet's history, and reveal the past existence of oceans. Such samples may persist on the Moon, which lacks an atmosphere and signifi…
Neutral Cr and V in the atmosphere of ultra hot jupiter WASP-121 b
Maya Ben-Yami, Nikku Madhusudhan, Samuel H. C. Cabot +4
Ultra hot jupiters (UHJs), giant exoplanets with equilibrium temperatures above 2000 K, are ideal laboratories for studying metal compositions of planetary atmospheres. At these te…
EXPRES I. HD~3651 an Ideal RV Benchmark
John M. Brewer, Debra A. Fischer, Ryan T. Blackman +10
The next generation of exoplanet-hunting spectrographs should deliver up to an order of magnitude improvement in radial velocity precision over the standard 1 m/s state of the art.…
High-resolution Transmission Spectroscopy of MASCARA-2 b with EXPRES
H. Jens Hoeijmakers, Samuel H. C. Cabot, Lily Zhao +10
We report detections of atomic species in the atmosphere of MASCARA-2 b, using the first transit observations obtained with the newly commissioned EXPRES spectrograph. EXPRES is a…
Performance Verification of the EXtreme PREcision Spectrograph
Ryan T. Blackman, Debra A. Fischer, Colby A. Jurgenson +25
The EXtreme PREcision Spectrograph (EXPRES) is a new Doppler spectrograph designed to reach a radial velocity measurement precision sufficient to detect Earth-like exoplanets orbit…
