Transmission spectroscopy for the warm sub-Neptune HD3167c: evidence for molecular absorption and a possible high metallicity atmosphere
Thomas Mikal-Evans, Ian J. M. Crossfield, Bjorn Benneke +26
We present a transmission spectrum for the warm (500-600K) sub-Neptune HD3167c obtained using the Hubble Space Telescope Wide Field Camera 3 infrared spectrograph. We combine these…
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…
The TESS-Keck Survey II: An Ultra-Short Period Rocky Planet and its Siblings Transiting the Galactic Thick-Disk Star TOI-561
Lauren M. Weiss, Fei Dai, Daniel Huber +61
We report the discovery of TOI-561, a multi-planet system in the galactic thick disk that contains a rocky, ultra-short period planet (USP). This bright () star hosts three…
Stellar Characterization of Keck HIRES Spectra with The Cannon
Malena Rice, John Brewer
To accurately interpret the observed properties of exoplanets, it is necessary to first obtain a detailed understanding of host star properties. However, physical models that analy…
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.…
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…
