Adjusting the bow-tie: A morpho-kinematic study of NGC40
J. B. Rodríguez-González, J. A. Toalá, L. Sabin +4
We present a comprehensive study of the ionization structure and kinematics of the planetary nebula (PN) NGC40 (a.k.a. the Bow-tie Nebula). A set of narrow-band images obtained wit…
The five axes of the Turtle: symmetry and asymmetry in NGC 6210
William J. Henney, J. A. López, Ma. T. García-Díaz +1
We carry out a comprehensive kinematic and morphological study of the asymmetrical planetary nebula: NGC 6210, known as the Turtle. The nebula's spectacularly chaotic appearance ha…
The Chandra Planetary Nebulae Survey (ChanPlaNS): III. X-ray Emission from the Central Stars of Planetary Nebulae
R. Montez, J. H. Kastner, B. Balick +25
We present X-ray spectral analysis of 20 point-like X-ray sources detected in Chandra Planetary Nebula Survey (ChanPlaNS) observations of 59 planetary nebulae (PNe) in the solar ne…
Internal Proper-Motions in the Eskimo Nebula
Ma. T. García-Díaz, L. Gutiérrez, W. Steffen +2
We present measurements of internal proper motions at more than five hundred positions of NGC 2392, the Eskimo Nebula, based on images acquired with WFPC2 on board the Hubble Space…
The Chandra Planetary Nebula Survey (ChanPlaNS). II. X-ray Emission from Compact Planetary Nebulae
M. Freeman, R. Montez, J. H. Kastner +24
We present results from the most recent set of observations obtained as part of the Chandra X-ray observatory Planetary Nebula Survey (ChanPlaNS), the first comprehensive X-ray sur…
Herschel Planetary Nebula Survey (HerPlaNS) - First Detection of OH+ in Planetary Nebulae
I. Aleman, T. Ueta, D. Ladjal +15
We report the first detections of OH emission in planetary nebulae (PNe). As part of an imaging and spectroscopy survey of 11 PNe in the far-IR using the PACS and SPIRE instrum…
