Top] [Prev] . This paper shows options for configuring a symmetric linear nulling array as a Planet Finder. Of special interest are linked in-line pairs of identical sub-arrays with a quarter wave phase shift between them and staggered by half an element spacing. The configuration of the optical links for general astrophysical use is also described. ...

... Calibration and analysis of this observation posed very interesting challenges for the authors, in particular dealing with an exciting new instrument whose on-orbit calibration was not yet well defined. ... Five mosaic positions were observed during five consecutive orbits as well as observations for dark and flat calibration. ... Darks and flats had to be created from contemporaneous reference observations and problems within the calibration process had to be resolved. ...

Starbursts are short-lived events, stars are forming so quickly that the reservoirs of interstellar gas from which stars are coalescing would be used up on a timescale much shorter than the age of the galaxy . ...

. Although this design reduces the vignetting seen at the NA2 guider. We do not have a good feeling yet what the effect might be on scattered light at the focal plane.

My research interests are focussed on the theory and modelling of accretion processes as well as star and planet formation mechanisms.
