Pluto's lower atmosphere structure and methane abundance from high-resolution spectroscopy and stellar occultations
E. Lellouch, B. Sicardy, C. de Bergh +3
Context: Pluto possesses a thin atmosphere, primarily composed of nitrogen, in which the detection of methane has been reported. Aims: The goal is to constrain essential but so far…
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…
Nuclear activity in nearby galaxies: Mid-infrared imaging with the VLT
R. Siebenmorgen, M. Haas, E. Pantin +7
Dust enshrouded activity can ideally be studied by mid-infrared (MIR) observations. In order to explore the AGN versus star forming origin of the nuclear MIR emission of galaxies,…
Sulphur and zinc abundances in Galactic halo stars revisited
P. E. Nissen, C. Akerman, M. Asplund +4
High resolution UVES spectra of 40 main-sequence stars with -3.3 < [Fe/H] < -1.0 are used to derive S, Fe and Zn abundances from lines in the 400 - 950 nm region. For one star we a…
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…
