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…
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…
Unveiling two deeply embedded young protostars in the S68N Class 0 protostellar core with JWST/NIRSpec
Valentin J. M. Le Gouellec, Ben W. P. Lew, Thomas P. Greene +11
The near-infrared (NIR) emission of the youngest protostars still needs to be characterized to better understand the evolution of their accretion and ejection activity. We analyze…
Identification of a turnover in the initial mass function of a young stellar cluster down to 0.5 M
Matthew De Furio, Michael R. Meyer, Thomas Greene +11
A successful theory of star formation should predict the number of objects as a function of their mass produced through star-forming events. Previous studies in star-forming region…
JWST/NIRCam Detection of the Fomalhaut C Debris Disk in Scattered Light
Kellen Lawson, Joshua E. Schlieder, Jarron M. Leisenring +20
Observations of debris disks offer important insights into the formation and evolution of planetary systems. Though M dwarfs make up approximately 80% of nearby stars, very few M-d…
JWST/NIRCam Imaging of Young Stellar Objects III: Detailed Imaging of the Nebular Environment Around the HL Tau Disk
Camryn Mullin, Ruobing Dong, Jarron Leisenring +13
As part of the James Webb Space Telescope (JWST) Guaranteed Time Observation (GTO) program "Direct Imaging of YSOs" (program ID 1179), we use JWST NIRCam's direct imaging mode in F…
High-precision atmospheric characterization of a Y dwarf with JWST NIRSpec G395H spectroscopy: isotopologue, C/O ratio, metallicity, and the abundances of six molecular species
Ben W. P. Lew, Thomas Roellig, Natasha E. Batalha +19
The launch of the James Webb Space Telescope (JWST) marks a pivotal moment for precise atmospheric characterization of Y dwarfs, the coldest brown dwarf spectral type. In this stud…
The outflow of the protostar in B335: I
Klaus W. Hodapp, Laurie L. Chu, Thomas Greene +10
The isolated globule B335 contains a single, low luminosity Class 0 protostar associated with a bipolar nebula and outflow system seen nearly perpendicular to its axis. We observed…
JWST/NIRCam Imaging of Young Stellar Objects. II. Deep Constraints on Giant Planets and a Planet Candidate Outside of the Spiral Disk Around SAO 206462
Gabriele Cugno, Jarron Leisenring, Kevin R. Wagner +17
We present JWST/NIRCam F187N, F200W, F405N and F410M direct imaging data of the disk surrounding SAO 206462. Previous images show a very structured disk, with a pair of spiral arms…
JWST/NIRCam Imaging of Young Stellar Objects. I. Constraints on Planets Exterior to The Spiral Disk Around MWC 758
Kevin Wagner, Jarron Leisenring, Gabriele Cugno +18
MWC 758 is a young star hosting a spiral protoplanetary disk. The spirals are likely companion-driven, and two previously-identified candidate companions have been identified -- on…
Searching for Planets Orbiting Fomalhaut with JWST/NIRCam
Marie Ygouf, Charles Beichman, Jorge Llop-Sayson +20
We report observations with the JWST/NIRCam coronagraph of the Fomalhaut system. This nearby A star hosts a complex debris disk system discovered by the IRAS satellite. Observation…
Two NIRCam channels are Better than One: How JWST Can Do More Science with NIRCam's Short-Wavelength Dispersed Hartmann Sensor
Everett Schlawin, Marcia Rieke, Jarron Leisenring +8
The James Webb Space Telescope (JWST) offers unprecedented sensitivity, stability, and wavelength coverage for transiting exoplanet studies, opening up new avenues for measuring at…
Toward Direct Imaging of Low-Mass Gas-Giants with the
Joshua E. Schlieder, Charles A. Beichman, Michael R. Meyer +1
In preparation for observations with the (), we have identified new members of the nearby, young M dwarf sample and compiled an…
