HIRES 2014: "Astronomy at high angular resolution – a cross-disciplinary approach"

Scientific Rationale

In 2000, a very successful workshop took place in Brussels about “Astrotomography”, a generic term for indirect mapping techniques that can be applied to a huge variety of astrophysical systems, ranging from planets via single stars and binaries to active galactic nuclei. It is now time to revisit the situation given the many past and coming improvements in instrumentation and telescopes. It is also useful to put this is a broader context of high-angular resolution astronomy, as many other techniques, from lucky and speckle imaging, adaptive optics to interferometry, are now becoming more and more used and have led to an amazing number of new discoveries.
With this workshop we plan to bring together people from different communities who use various techniques to construct images at very high angular resolution. In the time since the first workshop, the scientific output of these methods has been considerable, the range of applications becoming larger and larger with time. It is thus timely to review these methods, the progress in the field, the new harvest of results that were collected, as well as to prepare the next generation of astronomers to use these tools and techniques.

Some of the themes to be covered by the meeting will be

  • Methods and techniques: lucky imaging, speckle imaging, adaptive optics, spectro-astrometry, interferometry, Astrotomography (Eclipse Mapping, Spot Mapping, Spectral Mapping, Echo Mapping, Spectral Disentangling, Doppler Tomography and Modulated Doppler Tomography, Roche Tomography, Zeeman-Doppler Mapping, Interferometric-Doppler imaging);
  • Planets, discs and brown dwarfs: interferometry study of young stellar discs, astrotomography of planets, AO imaging of planets and discs, brown dwarf Doppler imaging;
  • Stars: Stellar interferometry, aperture masking imaging, hot and cool stars, (Zeeman) Doppler imaging, spectro-astrometry, mass loss;
  • Binaries: disentangling of stellar spectra, Roche tomography, Stokes imaging;
  • Large scale phenomena: AGN reverberation mapping, AGN interferometry;
  • Instrumentation: current and future instrumentationHere you provide a more or less comprehensive description of the Scientific Rational of the Conference or Workshopö;
  • Solar imaging.
