Shaping bipolar Planetary Nebulae : How mass loss leads to waistline development
Catharinus Dijkstra, Angela Speck
Asymptotic Giant Branch (AGB) stars generally have spherically symmetric envelopes, whereas most post-AGB stars and Planetary Nebulae (PNe) show axisymmetric circumstellar envelope…
Detection of a Far-Infrared Bow-Shock Nebula Around R Hya: the First MIRIAD Results
T. Ueta, A. K. Speck, R. E. Stencel +10
We present the first results of the MIRIAD (MIPS [Multiband Imaging Photometer for Spitzer] Infra-Red Imaging of AGB [asymptotic giant branch] Dustshells) project using the Spitzer…
The Multitude of Molecular Hydrogen Knots in the Helix Nebula
Margaret Meixner, Peter McCullough, Joel Hartman +2
We present HST/NICMOS imaging of the H_2 2.12 μm emission in 5 fields in the Helix Nebula ranging in radial distance from 250-450" from the central star. The images reveal arcuate…
