The JWST/NIRCam Scattered Light Disks GTO 2780 program: panchromatic coronagraphic imaging of the HD 10647, HD 32297, HD 61005, HD 107146, and HD 181327 debris disk systems
András Gáspár, Jarron M. Leisenring, Schuyler Grace Wolff +13
Debris disks, composed of rocks, boulders, planetesimals, and the dust produced in their collisions, present the most readily observable components of mature planetary systems. The…
JWST/NIRCam Imaging of Young Stellar Objects. IV. Detailed Imaging of the Protoplanetary Disk around TW Hya
Yu-Chia Lin, Jarron Leisenring, Schuyler G. Wolff +14
As the nearest protoplanetary disk to Earth ( pc), TW Hya is one of the most studied protoplanetary disks and a critical benchmark for testing planet formation theories.…
JWST spectral retrieval of cold directly imaged planet WD0806 b and the first measurement of altitude-dependent K in exoplanet atmospheres
Ben W. P. Lew, Thomas Roellig, Natasha E. Batalha +10
WD0806 b is a rare exoplanet companion orbiting a white dwarf, currently with a projected orbital distance of 2500 au. The Spitzer mid-IR photometry suggests that the temperature i…
The Outflow of the B335 Protostar II: After the Outburst
Klaus W. Hodapp, Adwin Boogert, Doug Johnstone +6
The B335 protostar has recently undergone a major, still ongoing, outburst detected in scattered light from its outflow cavity, offering a rare opportunity to study its impact on a…
A Panchromatic Characterization of the Evening and Morning Atmosphere of WASP-107 b: Composition and Cloud Variations, and Insight into the Effect of Stellar Contamination
Matthew M. Murphy, Thomas G. Beatty, Everett Schlawin +16
Limb-resolved transmission spectroscopy has the potential to transform our understanding of exoplanetary atmospheres. By separately measuring the transmission spectra of the evenin…
Probing the Outskirts of M Dwarf Planetary Systems with a Cycle 1 JWST NIRCam Coronagraphy Survey
Ellis Bogat, Joshua E. Schlieder, Kellen D. Lawson +18
The population of giant planets on wide orbits around low-mass M dwarf stars is poorly understood, but the unprecedented sensitivity of JWST NIRCam coronagraphic imaging now provid…
A JWST Panchromatic Thermal Emission Spectrum of the Warm Neptune Archetype GJ 436b
Sagnick Mukherjee, Everett Schlawin, Taylor J. Bell +10
GJ 436b is the archetype warm Neptune exoplanet. The planet's thermal emission spectrum was previously observed via intensive secondary eclipse campaigns with Spitzer. The atmosphe…
Possible Carbon Dioxide Above the Thick Aerosols of GJ 1214 b
Everett Schlawin, Kazumasa Ohno, Taylor J. Bell +14
Sub-Neptune planets with radii smaller than Neptune (3.9 Re) are the most common type of planet known to exist in The Milky Way, even though they are absent in the Solar System. Th…
A Possible Metal-Dominated Atmosphere Below the Thick Aerosols of GJ 1214 b Suggested by its JWST Panchromatic Transmission Spectrum
Kazumasa Ohno, Everett Schlawin, Taylor J. Bell +9
GJ1214b is the archetype sub-Neptune for which thick aerosols have prevented us from constraining its atmospheric properties for over a decade. In this study, we leverage the panch…
Multiple Clues for Dayside Aerosols and Temperature Gradients in WASP-69 b from a Panchromatic JWST Emission Spectrum
Everett Schlawin, Sagnick Mukherjee, Kazumasa Ohno +16
WASP-69 b is a hot, inflated, Saturn-mass planet 0.26 Mjup with a zero-albedo equilibrium temperature of 963 K. Here, we report the JWST 2 to 12 um emission spectrum of the planet…
Evidence for Morning-to-Evening Limb Asymmetry on the Cool Low-Density Exoplanet WASP-107b
Matthew M. Murphy, Thomas G. Beatty, Everett Schlawin +8
The atmospheric properties of hot exoplanets are expected to be different between the morning and the evening limb due to global atmospheric circulation. Ground-based observations…
Mid-Infrared IRS Spectroscopy of NGC 7331: A First Look at the SINGS Legacy
J. D. T. Smith, D. A. Dale, L. Armus +22
The nearby spiral galaxy NGC 7331 was spectrally mapped from 5-38um using all modules of Spitzer's IRS spectrograph. A strong new dust emission feature, presumed due to PAHs, was d…
HST Paschen alpha and 1.9 micron imaging of Sgr A West
N. Z. Scoville, S. R. Stolovy, M. Rieke +2
We present HST/NICMOS images at 0.2" resolution of the HI Paschen Alpha (PaA) emission line in a 70" x 90" region of the Galactic center centered on the non-thermal radio source Sg…
