Imaging the Ionized Disk of the High-Mass Protostar Orion–I
We have imaged the enigmatic radio source-I (Orion–I) in the Orion-KL nebula with the VLA at 43 GHz with 34 mas angular resolution. The continuum emission is highly elongated and is consistent with that expected from a nearly edge-on disk. The high brightness and lack of strong molecular lines from Orion– I can be used to argue against emission from dust. Collisional ionization and H free-free ...
متن کاملThe Warped Circumstellar Disk of Hd100546
We propose that the two armed spiral features seen in visible Hubble Space Telescope images of scattered light in HD100546’s circumstellar disk are caused by the illumination of a warped outer disk. A tilt of 6-15 degrees from the symmetry plane can cause the observed surface brightness variations providing the disk is very twisted (highly warped) at radii greater than 200 AU where the spiral f...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولThe Warped Debris Disk of Hd100546
We propose that the two armed spiral features seen in visible HST images of scattered light in HD100546’s debris disk are caused by surface gradient variation of a warped optically thin disk. A tilt of 6-10 degrees from the symmetry plane can cause the observed surface brightness variations providing the disk is geometrically thin, optically thin and very twisted (highly warped) at radii greate...
متن کاملThe Monoceros R2 Molecular Cloud
The Monoceros R2 region was first recognized as a chain of reflection nebulae illuminated by Aand B-type stars. These nebulae are associated with a giant molecular cloud that is one of the closest massive star forming regions to the Sun. This chapter reviews the properties of the Mon R2 region, including the namesake reflection nebulae, the large scale molecular cloud, global star formation act...
