We evaluate the direct detection of extrasolar giant planets with a two-aperture nulling infrared interferometer, working at angles θ < λ/2B and using a new "ratio-of-two-wavelengths" technique. Simple arguments suggest that interferometric detection and characterization should be quite possible for planets much closer than the conventional inner working angle, or angular resolution limit. We show that the peak signal from a nulling infrared interferometer of baseline ≲40 m will often occur… 
The Fourier-Kelvin Stellar Interferometer: A Progress Report and Preliminary Results from our Laboratory Testbed
The Fourier-Kelvin Stellar Interferometer (FKSI) is a passively cooled, space-borne interferometer that has been developed for high angular resolution astrophysics in the near-to-mid IR wavelength
Design of a laboratory simulator to test exoplanet imaging polarimetry
Research on extrasolar planets is one of the most rapidly advancing fields of astrophysics. In just over a decade since the discovery of the first extra-solar planet orbiting around 51 Pegasi, 289
Combination of nulling interferometer and modified pupil for observations of exo-planets
We consider a combination of two techniques, namely the nulling interferometer and halo suppression by modified pupil such as shaped pupils and apodized square apertures, which achieves very high
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
Characterisation of zodiacal environment of stellar targets for future missions dedicated to the direct detection of extrasolar planets
The level of brightness and the structure of exozodiacal dust clouds is identified for a long time as a limiting factor for the direct detection of extrasolar planets, their imaging and the
One of the biggest challenges associated with a nulling-interferometer-based approach to detecting extrasolar Earth-like planets comes from the extremely stringent requirements of path length,
Detection and Characterization of Extra‐Solar Planets: Future Space Missions
Various techniques are being used to search for extra‐solar planetary signatures, including accurate measurement of positional (astrometric) displacements, gravitational microlensing, and photometric
The Dynamical Influence of a Planet at Semimajor Axis 3.4 A on the Dust around Epsilon Eridani
Precise Doppler experiments suggest that a massive (m sin i = 0.86MJ) planet orbits at semimajor axis a = 3.4 AU around ϵ Eri, a nearby star with a massive debris disk. The dynamical perturbations
Nulling interferometry: performance comparison between space and ground-based sites for exozodiacal disc detection
Context. Characterising the circumstellar dust around nearby main sequence stars is a necessary step in understanding the planetary formation process and is crucial for future life-finding space

The synthesized point-spread function for a rotating nulling interferometer utilizing phase chopping is shown to consist of a main peak, satellite peaks, and their associated sidelobes, and simple analytic expressions are derived for the modulation efficiency and angular resolution.


An Imaging Nulling Interferometer to Study Extrasolar Planets
Interferometric techniques offer two advantages for the detection and analysis of thermal radiation from planets: destructive interference to strongly suppress the stellar emission, and the
Detecting nonsolar planets by spinning infrared interferometer
THE only known planets are the nine in our Solar System, so the origin of the Solar System and of stars in general would be clarified if other planetary systems could be discovered. Likewise,
Theoretical Transmission Spectra during Extrasolar Giant Planet Transits
The recent transit observation of HD 209458 b—an extrasolar planet orbiting a Sun-like star—confirmed that it is a gas giant and determined that its orbital inclination is 85°. This inclination makes
