Identification of the exciting source of Herbig-Haro objects 135 and 136
Tamura, M.; Hough, J.; Chrysostomou, A.; Itoh, Y.; Murakawa, K.; Bailey, J. (1997)We have identified the exciting source of the Herbig-Haro objects HH135 and 136 by near-infrared polarimetric imaging of the associated extensive reflection nebula. The source is situated at the middle of the two Herbig-Haro ... -
The magnetic field structure of the DR21 region
Itoh, Y.; Chrysostomou, A.; Burton, M.; Hough, J.; Tamura, M. (1999)We present results of imaging polarimetry of the H2 v=1--0 S(1) line towards the outflow lobes of DR21. The polarization vectors are produced by dichroic absorption in a medium of aligned grains and therefore delineate the ... -
Magnetic Fields in Star Forming Regions - Near-Infrared and Submillimeter Approaches
Tamura, M.; Hayashi, S.; Itoh, Y.; Hough, J.; Chrysostomou, A. (Astronomical Society of the Pacific, 1996)In order to study the magnetic field structure in star forming regions on various scales, we have been conducting both near-infrared and submillimeter polarimetry toward nearby molecular clouds. The near-infrared approach ... -
Near infrared coronagraph images of IRC +10216 - Faint structures at 1-5 from the central star
Murakawa, K.; Tamura, M.; Suto, H.; Itoh, Y.; Hayashi, S.; Oasa, Y.; Nakajima, Y.; Kaifu, N.; Yates, J.A.; Gledhill, T.; Richards, A.M.S.; Hough, J.; Kosugi, G.; Usuda, T. (2002)
