Aligned grains and inferred toroidal magnetic fields in the envelopes of massive young stellar objects
Janet P. Simpson, Barbara A. Whitney, Dean C. Hines +6
Massive young stellar objects (YSOs), like low-mass YSOs, are thought to be surrounded by optically thick envelopes and/or discs and are observed to have associated regions that pr…
Early Science with SOFIA, the Stratospheric Observatory for Infrared Astronomy
E. T. Young, E. E. Becklin, P. M. Marcum +38
The Stratospheric Observatory for Infrared Astronomy (SOFIA) is an airborne observatory consisting of a specially modified Boeing 747SP with a 2.7-m telescope, flying at altitudes…
Hubble Space Telescope NICMOS Polarization Observations of Three Edge-on Massive YSOs
Janet P. Simpson, Michael G. Burton, Sean W. J. Colgan +4
Massive young stellar objects (YSOs), like low-mass YSOs, appear to be surrounded by optically thick envelopes and/or disks and have regions, often bipolar, that are seen in polari…
Training of Instrumentalists and Development of New Technologies on SOFIA
Edwin F. Erickson, Louis J. Allamandola, Jean-Paul Baluteau +47
This white paper is submitted to the Astronomy and Astrophysics 2010 Decadal Survey (Astro2010)1 Committee on the State of the Profession to emphasize the potential of the Stratosp…
Spitzer Observations of M33 and the Hot Star, H II Region Connection
Robert H. Rubin, Janet P. Simpson, Sean W. J. Colgan +7
We have observed emission lines of [S IV] 10.51, H(7-6) 12.37, [Ne II] 12.81, [Ne III] 15.56, and [S III] 18.71 um in a number of extragalactic H II regions with the Spitzer Space…
NICMOS Observations of Shocked H_2 in Orion
Sean W. J. Colgan, A. S. B. Schultz, M. J. Kaufman +2
HST NICMOS narrowband images of the shocked molecular hydrogen emission in OMC-1 are analyzed to reveal new information on the BN/KL outflow. The outstanding morphological feature…
