Opis

The workshop on The Very Large Telescope Interferometer: Challenges for the Future, which was part of JENAM 2002 organised by Sociedade Portuguesa de Astronomia, took place at the Departamentos de Matematica Aplicada e Matemclt ica Pura da Universidade do Porto (FCUP) from the 5th to the 7th of September 2002. The Very Large Telescope Interferometer (VLTI) is the major interferometric facility in the world, operated by the European Southern Observatory. It is a unique facility as it is available to the community and has a sensitivity that will bring into reach vast classes of objects in the fields of planet searches, star formation and evolution and extragalatic astrophysics. The VLTI was open to the community on a shared risk basis in March 2002. This workshop was therefore an ideal place to obtain a broad view of optical interferometry and its scientific prospects. The workshop started with a presentation of the basics of interferometry the ory/practice, then of the VLT, Keck and LBT interferometers. The VLTI instru ments MIDI and AMBER were introduced to its users as well as specific cal ibration and modelling tools. The bulk of the workshop addressed astrophysics being currently done with interferometers with very high quality reviews in the fields star formation, imaging, pulsating stars, Mira stars, active stellar shells and extragalactic astronomy. The workshop featured some talks presenting fresh VLTI data using the VINCI commissioning instrument.
