This special section is dedicated to starshades: science, engineering, technology, and
programmatics. Our reasons for organizing this special section are several fold. First as a …

The Habitable Exoplanet Observatory (HabEx) is a conceptual space-based 4-m telescope
with the means to image and characterize potentially habitable planets orbiting Sun-like …

Starshades are a leading technology to enable the detection and spectroscopic
characterization of Earth-like exoplanets. We report on optical experiments of sub-scale …

We present a design for an active telescope for space astronomy. The telescope is capable
of both exoplanet work and general astronomy over wavelengths from∼ 100 nm up to 5 μm …

Exo-S is a probe-class mission study that includes the Dedicated mission, a 30 m starshade
co-launched with a 1.1 m commercial telescope in an Earth-leading deep-space orbit, and …

A key challenge for starshades is formation flying. To successfully image exoplanets, the
telescope boresight and starshade must be aligned to∼ 1 m at separations of tens of …

Starshade Imaging Simulation Toolkit for Exoplanet Reconnaissance (SISTER) is a versatile
tool designed to provide accurate models of the images of exoplanet systems when …

Starshade concepts must be stowed within rocket fairings for launch and then deployed in
space. The in-plane deployment accuracy must be on the order of hundreds of micrometers …

We lay out the capabilities and limitations of starshade-based missions aiming to measure
the reflected light spectra of temperate planets from an imaging perspective. We use the …

We present a fast algorithm for computing the diffracted field from arbitrary binary (sharp-
edged) planar apertures and occulters in the scalar Fresnel approximation for up to …
