Resolving the Multiple Outflows in the Egg Nebula with Keck II Laser Guide Star Adaptive Optics
D. Le Mignant, R. Sahai, A. Bouchez +10
The Egg Nebula has been regarded as the archetype of bipolar proto-planetary nebulae, yet we lack a coherent model that can explain the morphology and kinematics of the nebular and…
Preplanetary Nebulae: An HST Imaging Survey and a New Morphological Classification System
Raghvendra Sahai, Mark Morris, Carmen Sánchez Contreras +1
Using the Hubble Space Telescope (HST), we have carried out a survey of candidate preplanetary nebulae (PPNs). We report here our discoveries of objects having well-resolved geomet…
The spatio-kinematical structure and distance of the pre-planetary nebula IRAS 19134+2131
Hiroshi Imai, Raghvendra Sahai, Mark Morris
Using the VLBA, we have observed H2O maser emission in the pre-planetary nebula IRAS 19134+2131(I19134), in which the H2O maser spectrum has two groups of emission features separat…
A Spitzer Study of the Mass Loss Histories of Three Bipolar Pre-Planetary Nebulae
Tuan Do, Mark Morris, Raghvendra Sahai +1
We present the results of far-infrared imaging of extended regions around three bipolar pre-planetary nebulae, AFGL 2688, OH 231.8+4.2, and IRAS 163423814, at 70 and 160 m wi…
Hydrodynamical simulations of the jet in the symbiotic star MWC 560 III. Application to X-ray jets in symbiotic stars
Matthias Stute, Raghvendra Sahai
In papers I and II in this series, we presented hydrodynamical simulations of jet models with parameters representative of the symbiotic system MWC 560. These were simulations of a…
The LMC's Top 250: Classification of the Most Luminous Compact 8 micron Sources in the Large Magellanic Cloud
Joel H. Kastner, Stephen L. Thorndike, Paul A. Romanczyk +4
To ascertain the nature of the brightest compact mid-infrared sources in the Large Magellanic Cloud (LMC), we have applied an updated version of the Buchanan et al. (2006) 2MASS-MS…
