Abstrakt

MATISSE is a mid-infrared spectro-interferometer combining the beams of

up to four Unit Telescopes or Auxiliary Telescopes of the Very Large

Telescope Interferometer (VLTI) of the European Southern Observatory.

MATISSE will constitute an evolution of the two-beam interferometric

instrument MIDI. New characteristics present in MATISSE will give access

to the mapping and the distribution of the material, the gas and

essentially the dust, in the circumstellar environments by using the

mid-infrared band coverage extended to L, M and N spectral bands. The

four beam combination of MATISSE provides an efficient uv-coverage: 6

visibility points are measured in one set and 4 closure phase relations

which can provide aperture synthesis images in the mid-infrared spectral

regime. We give an overview of the instrument including the expected

performances and a view of the Science Case. We present how the

instrument would be operated. The project involves the collaborations of

several agencies and institutes: the Observatoire de la Côte

d’Azur of Nice and the INSU-CNRS in Paris, the Max Planck Institut

für Astronomie of Heidelberg; the University of Leiden and the

NOVA-ASTRON Institute of Dwingeloo, the Max Planck Institut für

Radioastronomie of Bonn, the Institut für Theoretische Physik und

Astrophysik of Kiel, the Vienna University and the Konkoly Observatory.
