Natural (such as lunar) occultations have long been used to study sources on small angular scales, while coronographs have been used to study high-contrast sources. We describe here the properties of the Big Occulting Steerable Satellite (BOSS), a large steerable occulting satellite to combine both of these techniques. BOSS will have several advantages over standard occulting bodies. BOSS would block all but about 4 × 10-5 of the light at 1 μm in the region of interest around the star for… 

UMBRAS: a matched occulter and telescope for imaging extrasolar planets

We describe a 1-meter space telescope plus free-flying occulter craft mission that would provide direct imaging and spectroscopic observations of Jovian and Uranus-sized planets about nearby stars

Occulter-based high-contrast exoplanet imaging: Design, scaling, and performance verification

Over the last two decades, a large number of exoplanets have been confirmed with the rate of discovery increasing in recent years primarily as new instruments with improved sensitivities have become

Occulter Design for THEIA N .

An occulter is an instrument designed to suppress starlight by diffraction from its edges; most are designed to be circular, with a set of identical “petals” running around the outside. Proposed

Optimal Occulter Design for Finding Extrasolar Planets

One proposed method for finding terrestrial planets around nearby stars is to use two spacecraft: a telescope and a specially shaped occulter that is specifically designed to prevent all but a tiny

Detection of Earth-like planets around nearby stars using a petal-shaped occulter

TLDR
Here is an occulter design that would achieve the required suppression and can be built with existing technology, and the compact mission architecture of a coronagraph is traded for the inconvenience of two spacecraft, but the daunting optics challenges are replaced with a simple deployable sheet.

Optimal design of petal-shaped occulters for extra-solar planet detection

One of the proposed methods for directly imaging extrasolar planets is via a free-flying occulter for blocking the starlight. The occulter would fly between a conventional telescope and the target

Imaging planets about other stars with UMBRAS

Direct imaging of terrestrial and Jupiter-size planets about other stars is a major goal of NASA's Origins Program and should be as well for the next generation of spaceborne telescopes. In this

Externally occulted terrestrial planet finder coronagraph: simulations and sensitivities

A multitude of coronagraphic techniques for the space-based direct detection and characterization of exo-solar terrestrial planets are actively being pursued by the astronomical community. Typical

The Advantages of Multiple Coronagraphic Vehicles in Occulter Missions

Free-flying external coronagraphs for space telescopes have been studied since the 1960s, but cost/ benefit analysis has not proved convincing for skeptics. A single space vehicle carrying an

Lunar Occultation of MACHOs

Lunar occultation can be used to measure the proper motions of some of the long time scale microlensing events, $t_{e} \gsim 70$ days, now being detected toward the Galactic bulge. The long events
