Hen 2-104: A close-up look at the Southern Crab
M. Santander-Garcia, R. L. M. Corradi, A. Mampaso +5
The kinematics, shaping, density distribution, expansion distance, and ionized mass of the nebula Hen 2-104, and the nature of its symbiotic Mira are investigated. A combination of…
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 Grand Challenge for Planetary Nebulae
Adam Frank, Orsola De Marco, Eric Blackman +1
The study of PN has been confronting a growing list of dilemmas which have yet to find coherent resolution. These issues are both observational and theoretical and can be stated as…
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…
PPN as Explosions: Bullets vs Jets and Nebular Shaping
Timothy J. Dennis, Andrew J. Cunningham, Adam Frank +3
Many proto-planetary nebulae (PPN) appear as narrow collimated structures sometimes showing multiple, roughly aligned lobes. In addition, many PPN flows have been shown to have sho…
