Water and OH Emission from the inner disk of a Herbig Ae/Be star
Steven C. Adams, Máté Ádámkovics, John S. Carr +2
We report the detection of hot HO and OH emission from the Herbig Ae/Be star HD using the Cryogenic Infrared Echelle Spectrograph on the $\textit{Very Large Telescop…
Protoplanetary Disk Sizes and Angular Momentum Transport
Joan R. Najita, Edwin A. Bergin
In young circumstellar disks, accretion--the inspiral of disk material onto the central star--is important for both the buildup of stellar masses and the outcome of planet formatio…
Spectrally Resolved Mid-Infrared Molecular Emission from Protoplanetary Disks and the Chemical Fingerprint of Planetesimal Formation
Joan R. Najita, John S. Carr, Colette Salyk +3
We present high resolution spectroscopy of mid-infrared molecular emission from two very active T Tauri stars, AS 205 N and DR Tau. In addition to measuring high signal-to-noise li…
Spiral Arms in Disks: Planets or Gravitational Instability?
Ruobing Dong, Joan R. Najita, Sean Brittain
Spiral arm structures seen in scattered light observations of protoplanetary disks can potentially serve as signposts of planetary companions. They can also lend unique insights in…
Spectroastrometric Study of Ro-vibrational CO Emission from the Herbig Ae star HD~179218 with iSHELL on the NASA Infrared Telescope Facility
Sean D. Brittain, John S. Carr, Joan R. Najita
We present analysis of commissioning band data acquired with the infrared echelle spectrograph (iSHELL) on {\it NASA's Infrared Telescope Facility}. In this paper we describe t…
Overview of the DESI Legacy Imaging Surveys
Arjun Dey, David J. Schlegel, Dustin Lang +157
The DESI Legacy Imaging Surveys are a combination of three public projects (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall z-band Legacy Surve…
