| Abstract: |
Much of our present-day knowledge of evolved late-type stars is based
on observations performed in the infrared wavelength regime, in
particular with space observatories. With their increasing sensitivity,
higher angular resolution, and improved spectral capabilities, each
new space mission has contributed to the great progress made in recent
decades. In this contribution I will present two future infrared space
missions and discuss what prospects they can offer to AGB research.
The first of these is the James Webb Space Telescope, which will have
a 6.5-m diameter primary mirror and is planned to be launched in 2018.
Most attention will be given to MIRI, the mid-infrared instrument which
provides direct imaging and medium-resolution spectroscopy (R∼3000)
over the wavelength range 5–28.8μm. MIRI also offers coronagraphic
imaging and low-resolution spectroscopic (R∼100, over 5–10μm)
capabilities. The second mission is SPICA: a “Space Infrared Telescope
for Cosmology and Astrophysics" which is at present in proposal phase.
SPICA will offer a large (3-m class) cooled telescope (<6°K)
and foresees scientific instruments covering the 20–210μm
wavelength range. |
