The physical and chemical processes in protoplanetary disks: constraints on the composition of comets
Yuri Aikawa, Satoshi Okuzumi, Klaus Pontoppidan
We review the recent observations of protoplanetary disks together with relevant theoretical studies with an emphasis on the evolution of volatiles. In the last several years Ataca…
Thirty Meter Telescope International Observatory Detailed Science Case 2024
Warren Skidmore, Bob Kirshner, David Andersen +168
The Thirty Meter Telescope (TMT) International Observatory (TIO) will be a revolutionary leap forward in astronomical observing capabilities, enabling us to address some of the mos…
Young Stellar Objects in NGC 346: A JWST NIRCam/MIRI Imaging Survey
Nolan Habel, Conor Nally, Laura Lenkic +17
We present a JWST imaging survey with NIRCam and MIRI of NGC 346, the brightest star-forming region in the Small Magellanic Cloud (SMC). By combining aperture and point spread func…
Retrievals of Protoplanetary Disk Parameters using Thermochemical Models: I. Disk Gas Mass from Hydrogen Deuteride Spectroscopy
Young Min Seo, Karen Willacy, Geoffrey Bryden +4
We discuss statistical relationships between the mass of protoplanetary disks and the hydrogen deuteride (HD) line emission and the dust spectral energy distribution (SED) determin…
Mid-Infrared Spectrum of the Disk around the Forming Companion GQ Lup B Revealed by JWST/MIRI
Gabriele Cugno, Polychronis Patapis, Andrea Banzatti +5
GQ Lup B is a forming brown dwarf companion () showing evidence for an infrared excess associated with a disk surronding the companion itself. Here we present mid-i…
