Piecewise estimates (filled circles) of the orbital period for a simulated HD type system (left) with and (right) without a 10 Earth mass companion in the interior 2:1 resonance. Signatures of resonant terrestrial planets in long-period systems Gareth F. Kennedy Rosemary A. Mardling Aim: Here we examine the possibility of indirectly detecting low-mass planets by measuring the change in period of an observable Jupiter-mass planet. For the observable planet orbit parameters from HD have been used; m * = 0.9 Solar masses, m p = 0.65 Jupiter masses and e o = The hypothetical companion planet has eccentricity of e i = 0.5 and is at a distance of δσ = from exact 2:1 resonance. We conclude that it is possible to indirectly detect low mass companions using this approach as long as sampling error < δP 0

Multiple aperture imaging and its application to Exo-Earth Imager Poster 62 Spectrometer (u,v) Plane Spatial Axis Spectral Axis Image Plane Spatial Axis (u,v) Plane Spatial Axis Spectral Axis Image Plane Spatial Axis New concept Conventional concept 1.We present a spectral imaging method for double- aperture interferometers. 2.We introduce the application to multi- aperture (>3) interferometers. 3.We present a new concept for Exo-Earth imager. Only two apertures allow us to acquire a spatially resolved image of an Exo-Earth. New concept for Exo-Earth imager Spectral imaging method for interferometers

Nakagawa, S. Higuchi, T. Sato, T. Wakayama, T. Yamamuro 3600sec Dark region (the raw contrast image) Dark region (the PSF subtracted image) PSF subtraction Background We pursued the checkerboard pupil mask coronagraph for SPICA mission. (Demonstration experiment using He-Ne laser in air →Enya et al, talk on Thursday ） Experiment To improve contrast more, we installed the insulated vacuum chamber and the temperature control system. Current status A contrast of 1.8×10 ⁻⁹ was achieved using the method of the PSF subtraction in the thermally stable condition. contrast~10 ⁻⁹
