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…

A Uniform Analysis of Debris Disks with the Gemini Planet Imager I: An Empirical Search for Perturbations from Planetary Companions in Polarized Light Images

Katie A. Crotts, Brenda C. Matthews, Gaspard Duchêne +37

The Gemini Planet Imager (GPI) has excelled in imaging debris disks in the near-infrared. The GPI Exoplanet Survey (GPIES) imaged twenty-four debris disks in polarized -band lig…

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…

Keck/KPIC Emission Spectroscopy of WASP-33b

Luke Finnerty, Tobias Schofield, Ben Sappey +29

We present Keck/KPIC high-resolution () -band thermal emission spectroscopy of the ultra-hot Jupiter WASP-33b. The use of KPIC's single-mode fibers greatly improves…
