Understanding Mass-Loss and the late Evolution of Intermediate Mass Stars: Jets, Disks, Binarity, Dust and Magnetic Fields
Raghvendra Sahai, Bruce Balick, Eric Blackman +7
Almost all stars in the 1-8 Msun range evolve through the Asymptotic Giant Branch (AGB), preplanetary nebula (PPN) and planetary nebula (PN) evolutionary phases. Most stars that le…
Towards a Spectral Technique for Determining Material Geometry Around Evolved Stars: Application to HD 179821
J. Nordhaus, I. Minchev, B. Sargent +6
HD 179821 is an evolved star of unknown progenitor mass range (either post-Asymptotic Giant Branch or post-Red Supergiant) exhibiting a double peaked spectral energy distribution (…
A disc in the heart of the Ant nebula
Foteini Lykou, Olivier Chesneau, Eric Lagadec +1
We present the discovery of a silicate disc at the centre of the planetary nebula Mz3 (the Ant). The nebula was observed with MIDI on the Very Large Telescope Interferometer (VLTI)…
A silicate disk in the heart of the Ant
Olivier Chesneau, Foteini Lykou, Bruce Balick +6
We aim at getting high spatial resolution information on the dusty core of bipolar planetary nebulae to directly constrain the shaping process. Methods: We present observations of…
Carbon Abundances in the Small Magellanic Cloud Planetary Nebulae
T. -H. Lee, L. Stanghellini, R. A. Shaw +2
As an ongoing study of Magellanic Cloud PNe we have obtained UV spectra of 9 PNe in the SMC to measure their carbon abundances. The spectra have been acquired with ACS HRC/PR200L a…
