Evidence for bipolar jets in late stages of AGB winds
D. Vinkovic, M. Elitzur, K. -H. Hofmann +1
Bipolar expansion at various stages of evolution has been recently observed in a number of AGB stars. The expansion is driven by bipolar jets that emerge late in the evolution of A…
The Most Detailed Picture Yet of an Embedded High-mass YSO
L. J. Greenhill, M. J. Reid, C. J. Chandler +2
High-mass star formation is not well understood chiefly because examples are deeply embedded, relatively distant, and crowded with sources of emission. Using VLA and VLBA observati…
IR emission from AGNs
Moshe Elitzur, Maia Nenkova, Zeljko Ivezic
Unified schemes of active galactic nuclei (AGN) require an obscuring dusty torus around the central source, giving rise to type 1 line spectrum for pole-on viewing and type 2 chara…
Topics in Basic Maser Theory
Moshe Elitzur
This review covers some of the developments in basic theory of astronomical masers over the past ten years. Topics included are the effects of three dimensional geometry and polari…
User Manual for DUSTY
Zeljko Ivezic, Maia Nenkova, Moshe Elitzur
DUSTY solves the problem of radiation transport in a dusty environment. The code can handle both spherical and planar geometries. The user specifies the properties of the radiation…
Stellar Outflows Driven by Radiation Pressure
Z. Ivezic, G. R. Knapp, M. Elitzur
We present a detailed, self-consistent model of radiatively driven stellar outflows which couples the radiative transfer and hydrodynamics equations. The circumstellar envelope, wh…
