Upper limits on CHOH in the HD 163296 protoplanetary disk: evidence for a low gas-phase CHOH/HCO ratio
M. T. Carney, M. R. Hogerheijde, V. V. Guzmán +6
Methanol (CHOH) is at the root of organic ice chemistry in protoplanetary disks. However, its weak emission has made detections difficult. To date, gas-phase CHOH has been…
Science with an ngVLA: High-resolution imaging of comets
M. A. Cordiner, C. Qi
Detailed mapping of the distributions and kinematics of gases in cometary comae at radio wavelengths can provide fundamental advances in our understanding of cometary activity and…
H2CO ortho-to-para ratio in the protoplanetary disk HD 163296
V. V. Guzman, K. I. Oberg, J. Carpenter +3
Ortho-to-para (o/p) ratios of species like water, ammonia and formaldehyde (H2CO) are believed to encode information about the formation history of the molecule. Measurements of o/…
A Subarcsecond ALMA Molecular Line Imaging Survey of the Circumbinary, Protoplanetary Disk Orbiting V4046 Sgr
Joel H. Kastner, C. Qi, D. A. Dickson-Vandervelde +6
We present a suite of ALMA interferometric molecular line and continuum images that elucidate, on linear size scales of 30--40 AU, the chemical structure of the nearby, evolv…
Exploring DCO as a tracer of thermal inversion in the disk around the Herbig Ae star HD163296
V. N. Salinas, M. R. Hogerheijde, N. M. Murillo +4
We aim to reproduce the DCO emission in the disk around HD163296 using a simple 2D chemical model for the formation of DCO through the cold deuteration channel and a parame…
Increased HCO production in the outer disk around HD 163296
M. T. Carney, M. R. Hogerheijde, R. A. Loomis +4
Three formaldehyde lines were observed (HCO 3--2, HCO 3--2, and HCO 3--2) in the protoplanetary disk around the Herbig Ae star…
