Disequilibrium Chemistry, Diabatic Thermal Structure, and Clouds in the Atmosphere of COCONUTS-2b
Zhoujian Zhang, Sagnick Mukherjee, Michael C. Liu +12
Located 10.888 pc from Earth, COCONUTS-2b is a planetary-mass companion to a young (150-800 Myr) M3 star, with a wide orbital separation (6471 au) and a low companion-to-host mass…
The metallicity and carbon-to-oxygen ratio of the ultra-hot Jupiter WASP-76b from Gemini-S/IGRINS
Megan Weiner Mansfield, Michael R. Line, Joost P. Wardenier +11
Measurements of the carbon-to-oxygen (C/O) ratios of exoplanet atmospheres can reveal details about their formation and evolution. Recently, high-resolution cross-correlation analy…
A Combined Ground-based and JWST Atmospheric Retrieval Analysis: Both IGRINS and NIRSpec Agree The Atmosphere of WASP-77A b is Metal-Poor
Peter Smith, Michael Line, Jacob Bean +12
Ground-based, high-resolution and space-based, low-resolution spectroscopy are the two main avenues through which transiting exoplanet atmospheres are studied. Both methods provide…
A Large and Variable Leading Tail of Helium in a Hot Saturn Undergoing Runaway Inflation
Michael Gully-Santiago, Caroline V. Morley, Jessica Luna +14
Atmospheric escape shapes the fate of exoplanets, with statistical evidence for transformative mass loss imprinted across the mass-radius-insolation distribution. Here we present t…
The Roasting Marshmallows Program with IGRINS on Gemini South I: Composition and Climate of the Ultra Hot Jupiter WASP-18 b
Matteo Brogi, Vanessa Emeka-Okafor, Michael R. Line +19
We present high-resolution dayside thermal emission observations of the exoplanet WASP-18b using IGRINS on Gemini South. We remove stellar and telluric signatures using standard al…
A Uniform Retrieval Analysis of Ultra-cool Dwarfs. IV. A Statistical Census from 50 Late-T Dwarfs
Joseph A Zalesky, Kezman Saboi, Michael R. Line +5
The spectra of brown dwarfs are key to exploring the chemistry and physics that take place in their atmospheres. Late-T dwarf spectra are particularly diagnostic due to their relat…
A solar C/O and sub-solar metallicity in a hot Jupiter atmosphere
Michael R. Line, Matteo Brogi, Jacob L. Bean +13
Measurements of the atmospheric carbon (C) and oxygen (O) relative to hydrogen (H) in hot Jupiters (relative to their host stars) provide insight into their formation location and…
The Gemini Planet Imager view of the HD 32297 debris disk
Gaspard Duchene, Malena Rice, Justin Hom +60
We present new -band scattered light images of the HD 32297 edge-on debris disk obtained with the Gemini Planet Imager (GPI). The disk is detected in total and polarized intensi…
A Uniform Retrieval Analysis of Ultracool Dwarfs. III. Properties of Y-Dwarfs
Joseph A. Zalesky, Michael R. Line, Adam C. Schneider +1
Ultra-cool brown dwarfs offer a unique window into understanding substellar atmospheric physics and chemistry. Their strong molecular absorption bands at infrared wavelengths, Jupi…
The Origin of Kepler-419b: A Path to Tidal Migration Via Four-body Secular Interactions
Jonathan M. Jackson, Rebekah I. Dawson, Joseph Zalesky
We test the high-eccentricity tidal migration scenario for Kepler-419b, a member of the eccentric warm Jupiter class of planets whose origin is debated. Kepler-419 hosts two known…
Gemini Planet Imager Observational Calibration XIII: Wavelength Calibration Improvements, Stability, and Nonlinearity
Schuyler G. Wolff, Kimberly Ward-Duong, Joe Zalesky +3
We present improvements to the wavelength calibration for the lenslet-based Integral Field Spectrograph (IFS), that serves as the science instrument for the Gemini Planet Imager (G…
