Abstract

We have conducted an exhaustive inventory of potential astrophysical "noise sources" with respect to the detection and characterisation of Earth-like planets, focusing on the specifics of the nulling interferometry technique. We have extrapolated their characterisation at these yet-to-be-attained resolution and sensitivity, from existing data and models. They range from stellar features and significant orbital motion of pegasides during exposure, to exozodiacal cloud structures, background galaxies and galactic cirrus emission. This enabled us to evaluate the offset between the various features a typical interferometric nulling field-of-view (FOV) is likely to exhibit in reality, and the simplified, planet-only, detection FOV model generally used. This work is complementary to precise nulling data model formalization and detection algorithms development (Thiebaut et al., this conference), together conducted in the frame of an ESA contract by an Alcatel Alenia Space-led consortium. As such, part of this work is under embedment into a Java open-source simulator (ORIGIN). This approach can be useful for less signal-entangling, direct imaging techniques.
