METIS - the Mid-infrared E-ELT Imager and Spectrograph
Bernhard R. Brandl, Rainer Lenzen, Eric Pantin +19
METIS, the Mid-infrared ELT Imager and Spectrograph (formerly called MIDIR), is a proposed instrument for the European Extremely Large Telescope (E-ELT), currently undergoing a pha…
The symmetric dust shell and the central star of the bipolar planetary nebula NGC 6537
M. Matsuura, A. A. Zijlstra, M. D. Gray +2
We present high-resolution images of the strongly bipolar planetary nebula NGC 6537, obtained with Hubble Space Telescope and with the infrared adaptive optics system on the Very L…
PAHs and crystalline silicates in the post-AGB star IRAS 16279-4757
M. Matsuura, A. A. Zijlstra, F. J. Molster +7
IRAS 16279-4757 belongs to a group of post-AGB stars showing both PAH bands and crystalline silicates. We present mid-infrared images, that resolve the object for the first time. T…
The composition and nature of the dust shell surrounding the binary AFGL 4106
F. J. Molster, L. B. F. M. Waters, N. R. Trams +8
We present infrared spectroscopy and imaging of AFGL~4106. The 2.4-5 micron ISO-SWS spectrum reveals the presence of a cool, luminous star (T_eff ~ 3750 K) in addition to an almost…
