High-Velocity Interstellar Bullets in IRAS05506+2414: A Very Young Protostar
Raghvendra Sahai, Mark Claussen, Carmen Sánchez Contreras +2
We have made a serendipitous discovery of an enigmatic outflow source, IRAS 05506+2414 (hereafter IRAS 05506), as part of a multi-wavelength survey of pre-planetary nebulae (PPNs).…
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…
Adaptive Optics Imaging of IRAS 18276-1431: a bipolar pre-planetary nebula with circumstellar "searchlight beams" and "arcs"
C. Sanchez Contreras, D. Le Mignant, R. Sahai +2
We present high-angular resolution images of the post-AGB nebula IRAS18276-1431 (also known as OH17.7-2.0) obtained with the Keck II Adaptive Optics (AO) system in its Natural Guid…
