JWST observations of segregated CO and CO ices in protostellar envelopes
N. G. C. Brunken, A. C. A. Boogert, E. F. van Dishoeck +13
The evolution of interstellar ices can be studied with thermal tracers such as the vibrational modes of CO ice that show great diversity depending on their local chemical and t…
JWST observations of CO ice: Tracing the chemical environment and thermal history of ices in protostellar envelopes
Nashanty G. C. Brunken, Will R. M. Rocha, Ewine F. van Dishoeck +38
The structure and composition of simple ices can be modified during stellar evolution by protostellar heating. Key to understanding the involved processes are thermal and chemical…
An HST Survey of Protostellar Outflow Cavities: Does Feedback Clear Envelopes?
Nolan M. Habel, S. Thomas Megeath, Joseph Jon Booker +10
We study protostellar envelope and outflow evolution using Hubble Space Telescope NICMOS or WFC3 images of 304 protostars in the Orion Molecular clouds. These near-IR images resolv…
Dynamical Evidence of a Spiral Arm--Driving Planet in the MWC 758 Protoplanetary Disk
Bin Ren, Ruobing Dong, Rob G. van Holstein +22
More than a dozen young stars host spiral arms in their surrounding protoplanetary disks. The excitation mechanisms of such arms are under debate. The two leading hypotheses -- com…
Multiband GPI Imaging of the HR 4796A Debris Disk
Christine H. Chen, Johan Mazoyer, Charles A. Poteet +36
We have obtained Gemini Planet Imager (GPI) J-, H-, K1-, and K2-Spec observations of the iconic debris ring around the young, main-sequence star HR 4796A. We applied several point-…
An Exo-Kuiper Belt and An Extended Halo around HD 191089 in Scattered Light
Bin Ren, Élodie Choquet, Marshall D. Perrin +70
We have obtained Hubble Space Telescope STIS and NICMOS, and Gemini/GPI scattered light images of the HD 191089 debris disk. We identify two spatial components: a ring resembling K…
