JWST-TST High Contrast: Medium-resolution spectroscopy reveals a carbon-rich circumplanetary disk around the young accreting exoplanet Delorme 1 AB b

Mathilde Mâlin, Kimberly Ward-Duong, Sierra L. Grant +21

Young accreting planetary-mass objects are thought to draw material from a circumplanetary disk (CPD) composed of gas and dust. While the gas within the disk is expected to dispers…

A Near-Infrared Spectral Library of Very Young Brown Dwarfs and Planetary-Mass Objects in the Orion Nebula Cluster

Elena Manjavacas, Mario Gennaro, Sarah Betti +3

Age-benchmark brown dwarfs' and planetary-mass objects' spectroscopy is key to characterize substellar evolution. In this paper we present the JHK medium resolution (R~3000) spectr…

Water ice in the debris disk around HD 181327

Chen Xie, Christine H. Chen, Carey M. Lisse +13

Debris disks are exoplanetary systems that contain planets, minor bodies (i.e., asteroids, Kuiper belt objects, comets, etc.), and micron-sized debris dust. Since water ice is the…

JWST-TST High Contrast: Asymmetries, dust populations and hints of a collision in the Pictoris disk with NIRCam and MIRI

Isabel Rebollido, Christopher C. Stark, Jens Kammerer +21

We present the first JWST MIRI and NIRCam observations of the prominent debris disk around Beta Pictoris. Coronagraphic observations in 8 filters spanning from 1.8 to 23~m provi…

The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems III: Aperture Masking Interferometric Observations of the star HIP 65426 at 3.8 um

Shrishmoy Ray, Steph Sallum, Sasha Hinkley +121

We present aperture masking interferometry (AMI) observations of the star HIP 65426 at as a part of the JWST Direct Imaging Early Release Science (ERS) program obtai…

The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems IV: NIRISS Aperture Masking Interferometry Performance and Lessons Learned

Steph Sallum, Shrishmoy Ray, Jens Kammerer +120

We present a performance analysis for the aperture masking interferometry (AMI) mode on board the James Webb Space Telescope Near Infrared Imager and Slitless Spectrograph (JWST/NI…

The Comprehensive Archive of Substellar and Planetary Accretion Rates

S. K. Betti, K. B. Follette, K. Ward-Duong +11

Accretion rates () of young stars show a strong correlation with object mass (); however, extension of the relation into the substellar regime is less certa…

Star-Gas Surface Density Correlations in Twelve Nearby Molecular Clouds I: Data Collection and Star-Sampled Analysis

Riwaj Pokhrel, Robert A. Gutermuth, Sarah K. Betti +15

We explore the relation between the stellar mass surface density and the mass surface density of molecular hydrogen gas in twelve nearby molecular clouds that are located at 1.5…
