Near-Infrared Fiber Imager for the VLTI

Abstract: Abstract.For detection of massive close-in exo-planets around other stars, a contrast of ∼ 0.3% is sufficient and can be achieved with state-of-the-art single-mode fibers as spatial filter. For lower-mass planets, much higher accuracy is neccessary. Apart from the atmosphere, there are several sources of noise which degrade the phase stability of interferometers based on bulk optics by changes in the optical path. For direct detection of low-mass exo-planets and for direct observation of convection on giant st… Show more

“…This in turn will improve the fringe stability of the instrument, allowing for high dynamical range observations, e.g. detection of very faint objects very close to bright stars (planets in orbit around other stars) or of surface structure on other stars (signature of convection) (Neuhäuser et al 2008). Finally, we remark that for the implementation of the sensor, only off-the-shelf integrated optical components have been used.…”
