چکیده
Context. In the fourth paper in this series, we identified that a pentagonal arrangement of five telescopes, using kernel-nulling beam combiner, shows notable advantages for some important performance metrics space-based mid-infrared nulling interferometer over several other considered configurations detection Earth-like exoplanets around solar-type stars.

The Importance of Phase in Nulling Interferometry and a Three-telescope Closure-phase Nulling Interferometer Concept
We discuss the theory of the Bracewell nulling interferometer and explicitly demonstrate that the phase of the ‘‘white light’’ null fringe is the same as the phase of the bright output from an ordinary stellar interferometer. As a consequence, a ‘‘closure phase’’ exists for a nulling interferometer with three or more telescopes. We calculate the phase offset as a function of baseline length for...
متن کاملNulling Data Reduction and On-sky Performance of the Large Binocular Telescope Interferometer
The Large Binocular Telescope Interferometer (LBTI) is a versatile instrument designed for highangular resolution and high-contrast infrared imaging (1.5-13μm). In this paper, we focus on the mid-infrared (8-13μm) nulling mode and present its theory of operation, data reduction, and onsky performance as of the end of the commissioning phase in March 2015. With an interferometric baseline of 14....
متن کاملInstrumental stability requirements for exoplanet detection with a nulling interferometer: variability noise as a central issue.
We revisit the nulling interferometer performances that are needed for direct detection and the spectroscopic analysis of exoplanets, e.g., with the DARWIN [European Space Agency-SCI 12 (2000)] or TPF-I [JPL Publ. 05-5, (2005)] missions. Two types of requirement are found, one concerning the mean value of the instrumental nulling function (nl(lambda)) and another regarding its stability. The st...

15 صفحه اولa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
