Planetary Nebulae: Exposing the Top Polluters of the ISM
Joseph L. Hora, Massimo Marengo, Howard A. Smith +2
The high mass loss rates of stars in their asymptotic giant branch (AGB) stage of evolution is one of the most important pathways for mass return from stars to the ISM. In the plan…
IC 4406: a radio-infrared comparison
L. Cerrigone, J. L. Hora, G. Umana +1
IC 4406 is a large (about 100'' x 30'') southern bipolar planetary nebula, composed by two elongated lobes, extending from a bright central region, where there is evidence for the…
Radio and Infrared observations of Transition Objects
L. Cerrigone, J. L. Hora, G. Umana +1
Observing objects in transition from pre- to young Planetary Nebula (PN), when the central star radiation starts to excite the envelope, can help us to understand the evolution of…
Spitzer's View of Planetary Nebulae
Joseph L. Hora
The Spitzer Space Telescope, NASA's Great Observatory for infrared astronomy, has made available new tools for the investigation of the infrared properties of planetary nebulae. Th…
Wide-Field Thermal Imaging of the Orion Nebula at High Spatial Resolution
L. K. Deutsch, M. Kassis, N. Smith +5
We describe multi-wavelength (8--20 micron), diffraction-limited, mid-infrared images of the OMC-1 cloud core in Orion, covering an approximately two arcminute area around the Trap…
HST/NICMOS Imaging of the Planetary Nebula Hubble 12
Joseph L. Hora, William B. Latter, Aditya Dayal +4
Images of Hubble 12 were obtained with the HST/NICMOS instrument in the F110W, F164N, and F166N filters of NIC1, and the F160W, F187N, F190N, F212N, F215N filters of NIC2. The imag…
