Combining optical spectroscopy and interferometry
arXiv:1312.3835 · doi:10.1002/asna.201312011
Abstract
Modern optical spectrographs and optical interferometers push the limits in the spectral and spatial regime, providing important new tools for the exploration of the universe. In this contribution I outline the complementary nature of spectroscopic & interferometric observations and discuss different strategies for combining such data. Most remarkable, the latest generation of "spectro-interferometric" instruments combine the milliarcsecond angular resolution achievable with interferometry with spectral capabilities, enabling direct constraints on the distribution, density, kinematics, and ionization structure of the gas component in protoplanetary disks. I will present some selected studies from the field of star- & planet formation and hot star research in order to illustrate these fundamentally new observational opportunities.
