Validation of elemental and isotopic abundances in late-M spectral types with the benchmark HIP 55507 AB system
Jerry W. Xuan, Jason J. Wang, Luke Finnerty +48
M dwarfs are common host stars to exoplanets but often lack atmospheric abundance measurements. Late-M dwarfs are also good analogs to the youngest substellar companions, which sha…
Atmospheric metallicity and C/O of HD 189733 b from high-resolution spectroscopy
Luke Finnerty, Jerry W. Xuan, Yinzi Xin +27
We present high-resolution -band emission spectra of the quintessential hot Jupiter HD 189733 b from the Keck Planet Imager and Characterizer (KPIC). Using a Bayesian retrieval…
Calibration Unit Design for High-Resolution Infrared Spectrograph for Exoplanet Characterization (HISPEC)
Ben Sappey, Quinn Konopacky, Nemanja Jovanovic +13
The latest generation of high-resolution spectrograph instruments on 10m-class telescopes continue to pursue challenging science cases. Consequently, ever more precise calibration…
JWST-TST High Contrast: Achieving direct spectroscopy of faint substellar companions next to bright stars with the NIRSpec IFU
Jean-Baptiste Ruffio, Marshall D. Perrin, Kielan K. W. Hoch +33
The JWST NIRSpec integral field unit (IFU) presents a unique opportunity to observe directly imaged exoplanets from 3-5 um at moderate spectral resolution (R~2,700) and thereby bet…
The development of HISPEC for Keck and MODHIS for TMT: science cases and predicted sensitivities
Quinn M. Konopacky, Ashley D. Baker, Dimitri Mawet +72
HISPEC is a new, high-resolution near-infrared spectrograph being designed for the W.M. Keck II telescope. By offering single-shot, R=100,000 between 0.98 - 2.5 um, HISPEC will ena…
Vortex Fiber Nulling for Exoplanet Observations: Implementation and First Light
Daniel Echeverri, Jerry Xuan, Nemanja Jovanovic +31
Vortex fiber nulling (VFN) is a single-aperture interferometric technique for detecting and characterizing exoplanets separated from their host star by less than a diffracted beam…
