Deuterated methanol toward NGC 7538-IRS1
Juan Ospina-Zamudio, Cécile Favre, Marina Kounkel +7
We investigate the deuteration of methanol towards the high-mass star forming region NGC 7538-IRS1. We have carried out a multi-transition study of CHOH, CHOH and of…
Kinematics of the Optically Visible YSOs Toward the Orion B Molecular Cloud
Marina Kounkel, Lee Hartmann, Mario Mateo +2
We present results from high resolution optical spectra toward 66 young stars in the Orion B molecular cloud to study their kinematics and other properties. Observations of the H$α…
Characterizing the stellar population of NGC 1980
Marina Kounkel, Lee Hartmann, Nuria Calvet +1
NGC 1980 is a young cluster that is located about 0.5 degrees south of the Orion Nebula Cluster (ONC). Recent studies by Bouy et al. and Pillitteri et al. have suggested that NGC 1…
An HST Survey for 100-1000 AU Companions around Young Stellar Objects in the Orion Molecular Clouds: Evidence for Environmentally Dependent Multiplicity
M. Kounkel, S. T. Megeath, C. A. Poteet +2
We present a near-IR survey for the visual multiples in the Orion molecular clouds region at separations between 100 and 1000 AU. These data were acquired at 1.6~m with the NICM…
Spectroscopic Binaries in the Orion Nebula Cluster and NGC 2264
Marina Kounkel, Lee Hartmann, John J. Tobin +3
We examine the spectroscopic binary population for two massive nearby regions of clustered star formation, the Orion Nebula Cluster and NGC 2264, supplementing the data presented b…
The Gould's Belt Very Large Array Survey II: The Serpens region
Gisela N. Ortiz-León, Laurent Loinard, Amy J. Mioduszewski +12
We present deep (Jy) radio continuum observations of the Serpens molecular cloud, the Serpens south cluster, and the W40 region obtained using the Very Large Array in it…
