A search for planets around nearby stars can be done with infrared interferometry. The photometric evidence will be direct, as opposed to radial velocity evidence which is indirect. And because the direct technique collects photons from the planet itself, it can also tell us about the atmosphere via spectroscopy.
Infrared (or longer) wavelengths provide a flux ratio advantage: in the solar system, the ratios of planetary to solar flux, for an external observer, are much greater in the infrared than in the visible.
Interferometry provides the advantage of spatial discrimination which gives us the potential to suppress star with respect to planet.
These notes focus on selected aspects of infrared (IR) interferometry, as applied to the problem of searching for planets around nearby stars, in the presence of zodiacal dust both in the Solar System and around the target star. The accompanying 27 pages of viewgraphs (VG) with figures and equations are an essential part of these notes. The original talk outline in VG 1 has been rearranged slightly for the present paper.
