A view of the solar neighbourhood: the local population of planetary nebulae and their mimics
the solar neighbourhood the local population
2011/1/10
We have, for the first time, compiled a nearly complete census of planetary nebulae (PNe) centred on the Sun. Our goal is the generation of an unbiased volume-limited sample, in order to answer some l...
Central Stars of Planetary Nebulae: New spectral classifications and catalogue
Central Stars Planetary Nebulae spectral classifications
2011/1/11
Context. There are more than 3000 true and probable known Galactic Planetary Nebulae (PNe), but only for 13% of them there is central star spectroscopic information available. Aims. To contribute to t...
Radio-continuum detections of Galactic Planetary Nebulae I. MASH PNe detected in large-scale radio surveys
Radio-continuum Galactic Planetary Nebulae I
2011/1/10
We present an updated and newly compiled radio-continuum data-base for MASH PNe detected in the extant large scale "blind" radio-continuum surveys (NVSS, SUMSS/MGPS-2 and PMN) and, for a small number ...
A Spitzer/IRS spectral study of a sample of galactic carbon-rich proto-planetary nebulae
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/27
Recent infrared spectroscopic observations have shown that proto-planetary nebulae (PPNs) are sites of active synthesis of organic compounds in the late stages of stellar evolution. This paper present...
