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…
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…
GOALS-JWST: Gas Dynamics and Excitation in NGC7469 revealed by NIRSpec
Marina Bianchin, Vivian U, Yiqing Song +36
We present new JWST-NIRSpec IFS data for the luminous infrared galaxy NGC7469: a nearby (70.6Mpc) active galaxy with a Sy 1.5 nucleus that drives a highly ionized gas outflow and a…
GOALS-JWST: Small neutral grains and enhanced 3.3 micron PAH emission in the Seyfert galaxy NGC 7469
Thomas S. -Y. Lai, Lee Armus, Marina Bianchin +36
We present James Webb Space Telescope (JWST) Near Infrared Spectrograph (NIRSpec) integral-field spectroscopy of the nearby luminous infrared galaxy, NGC 7469. We take advantage of…
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…
Detecting exomoons from radial velocity measurements of self-luminous planets: application to observations of HR 7672 B and future prospects
Jean-Baptiste Ruffio, Katelyn Horstman, Dimitri Mawet +36
The detection of satellites around extrasolar planets, so called exomoons, remains a largely unexplored territory. In this work, we study the potential of detecting these elusive o…
Modeling Strong Lenses from Wide-Field Ground-Based Observations in KiDS and GAMA
Shawn Knabel, B. W. Holwerda, J. Nightingale +13
Despite the success of galaxy-scale strong gravitational lens studies with Hubble-quality imaging, the number of well-studied strong lenses remains small. As a result, robust compa…
GOALS-JWST: Pulling Back the Curtain on the AGN and Star Formation in VV 114
J. Rich, S. Aalto, A. S. Evans +33
We present results from the James Webb Space Telescope (JWST) Director's Discretionary Time Early Release Science (ERS) program 1328 targeting the nearby, Luminous Infrared Galaxy…
