The trigger of the AGB superwind: the importance of carbon
Eric Lagadec, Albert A. Zijlstra
The driving mechanism of the AGB superwind has become controversial in recent years. The efficacy of dust-driven mass loss has been queried. Spitzer observation of AGB stars in Loc…
Initial Data Release from the INT Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS)
E. A. Gonzalez-Solares, N. A. Walton, R. Greimel +47
The INT/WFC Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS) is an imaging survey being carried out in H-alpha, r' and i' filters, with the Wide Field Camera (WFC)…
Dust mass-loss rates from AGB stars in the Fornax and Sagittarius dwarf Spheroidal galaxies
Eric Lagadec, Albert A. Zijlstra, Mikako Matsuura +3
To study the effect of metallicity on the mass-loss rate of asymptotic giant branch (AGB) stars, we have conducted mid-infrared photometric measurements of such stars in the Sagitt…
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…
Spitzer Space Telescope spectral observations of AGB stars in the Fornax dwarf spheroidal galaxy
M. Matsuura, A. A. Zijlstra, J. Bernard-Salas +10
We have observed five carbon-rich AGB stars in the Fornax dwarf spheroidal (dSph) galaxy, using the Infrared Spectrometer on board the Spitzer Space Telescope. The stars were selec…
