High-contrast Coronagraphic Techniques
The direct detection of very faint companions to bright stars requires the development of effective high-contrast detection techniques, and the past decade has seen remarkable conceptual and instrumental progress in this area. New coronagraphic and interferometric techniques are regularly being deployed for on-sky tests and observations, and extreme ...

Future Exoplanet Research: High-Contrast Imaging Techniques
High-contrast imaging (HCI) techniques appear like the best solutions to directly characterize large orbit planets and planetary environments in the future. The first dedicated scientific instruments like SPHERE on VLT and GPI on Gemini South have only been commissioned in 2013-2014.

First Observations of the Brown Dwarf HD 19467 B with JWST
We observed HD 19467 B with JWST’s NIRCam in six filters spanning 2.5–4.6 μ m with the long-wavelength bar coronagraph. The brown dwarf HD 19467 B was initially identified through a long-period trend in the radial velocity of the G3V star HD 19467.

Detecting Exoplanets Closer to Stars with Moderate Spectral Resolution Integral-field Spectroscopy
While radial velocity surveys have demonstrated that the population of gas giants peaks around 3 au, the most recent high-contrast imaging surveys have only been sensitive to planets beyond ∼10 au.

Angular Differential Imaging: A Powerful High‐Contrast Imaging Technique [PDF]
Angular differential imaging is a high-contrast imaging technique that reduces quasi-static speckle noise and facilitates the detection of nearby companions. A sequence of images is acquired with an altitude/azimuth telescope while the instrument field derotator is switched off.
