FLIP SOFTWARE SUBTRACTS STARLIGHT IN JWST CORONAGRAPH DATA WITH UP TO 15X BETTER SENSITIVITY

Summary from the TLDR Hardware newsletter

A Northwestern-led team built FLIP, which makes a physics-based digital twin of the telescope's optics and adjusts it until it reproduces the observed starlight, then subtracts that simulated glare. On existing NIRCam data at 4.3 microns, it improved sensitivity up to 15x over the conventional KLIP method and recovered the giant planet 51 Eridani b, which standard processing couldn't separate from residual glare.
