A scheme to optimally design a beam combiner is discussed for any pre-determined fixed geometry nulling interferometer aimed at detection and characterization of exoplanets with multiple telescopes or a single telescope (aperture masking). We show that considerably higher order nulls can be achieved with 1-D interferometer geometries than possible with 2-D geometries with the same number of apertures. Any 1-D interferometer with N apertures can achieve a 2(N-1)-order null, while the order of…

Kernel nullers for an arbitrary number of apertures
This work introduces a convenient graphical representation of the complex combiner matrices that model the kernel nuller and highlights the symmetry properties that enable the formation of kernel nulls.
Kernel-nulling for a robust direct interferometric detection of extrasolar planets
This work introduces a modified nuller architecture that enables the extraction of information that is robust against piston excursions, and presents the properties of VIKiNG: the VLTI Infrared Kernel NullinG, an instrument concept within the Hi-5 framework for the 4-UT VL TI infrastructure that takes advantage of the proposed architecture, to produce three self-calibrating nulled outputs.

It is argued that in order to fast-track the inevitability of space interferometry, some key subsystem development, whole mission simulation and a pathfinder mission are all required in the near future.
Simulating the Exoplanet Yield of a Space-based MIR Interferometer Based on Kepler Statistics
Aims: We predict the exoplanet yield of a space-based mid-infrared nulling interferometer using Monte Carlo simulations. We quantify the number and properties of detectable exoplanets and identify

Suppression of starlight by nulling interferometry has the potential to enable the direct detection of planets around nearby stars, and several interferometer configurations have been proposed which
Three telescope nuller based on multibeam injection into single-mode waveguide
Nulling interferometry of exo-solar planets requires as a minimum two telescopes, of which one is phase shifted by 180 degrees, such that the on-axis stellar object is cancelled, while the light from
Nulling interferometry without achromatic phase shifters.
This work investigates the nulling depth as a function of the width of the wavelength interval and the number of telescopes, and shows that it can obtain nulling depths of less than 10(-6), which are required for exoplanet detection.
Deep nulling by means of multiple-beam recombination.
It is shown that the 2-mrad constraint can be relaxed if more than two beams participate in the beam recombination and that rejection ratios beyond 10(6) can be reached easily by use of a system of four or more apertures and simple dispersive phase shifters that consist of only one material.
Array Configurations for a Space Infrared Nulling Interferometer Dedicated to the Search for Earthlike Extrasolar Planets
Abstract Recent studies show that an infrared nulling interferometer dedicated to the detection and spectroscopy of exoplanetary systems must fulfill three main requirements. It must provide very
