  The study of protoplanetary disks has become increasingly important with the
Kepler satellite finding that exoplanets are ubiquitous around stars in our
galaxy and the discovery of enormous diversity in planetary system
architectures and planet properties. High-resolution near-IR and ALMA images
show strong evidence for ongoing planet formation in young disks. The JWST MIRI
mid-INfrared Disk Survey (MINDS) aims to (1) investigate the chemical inventory
in the terrestrial planet-forming zone across stellar spectral type, (2) follow
the gas evolution into the disk dispersal stage, and (3) study the structure of
protoplanetary and debris disks in the thermal mid-IR. The MINDS survey will
thus build a bridge between the chemical inventory of disks and the properties
of exoplanets. The survey comprises 52 targets (Herbig Ae stars, T Tauri stars,
very low-mass stars and young debris disks). We primarily obtain MIRI/MRS
spectra with high S/N (~100-500) covering the complete wavelength range from
4.9 to 27.9 {\mu}m. For a handful of selected targets we also obtain NIRSpec
IFU high resolution spectroscopy (2.87-5.27 {\mu}m). We will search for
signposts of planet formation in thermal emission of micron-sized dust -
information complementary to near-IR scattered light emission from small dust
grains and emission from large dust in the submillimeter wavelength domain. We
will also study the spatial structure of disks in three key systems that have
shown signposts for planet formation, TW Hya and HD 169142 using the MIRI
coronagraph at 15.5 {\mu}m and 10.65 {\mu}m respectively and PDS70 using NIRCam
imaging in the 1.87 {\mu}m narrow and the 4.8 {\mu}m medium band filter. ...
