Exoplanetary Circumstellar Environments and Disk Explorer(EXCEDE) is a proposedspace telescope forNASA'sExplorer program to observe circumstellarprotoplanetary anddebris discs and studyplanet formation around nearby (within 100parsecs)stars ofspectral classes M to B.^[1] Had it been selected for development, it was proposed to launch in 2019.

The spacecraft concept proposed to use a 70 centimeter diameter telescope-mountedcoronagraph calledPIAA (Phase Induced Amplitude Apodized Coronagraph) to suppress starlight in order to be able to detect fainter radiation of circumstellar dust.^[1] Characterizing constitution of such disks would provide clues for planetary formation (mostly inhabitable zones), while already existingexoplanets can be detected through their interaction with dust disk. The project's Principal Investigator isGlenn Schneider.^[1]

Science goals

[edit]

The science goals of the concept mission are:^[1]

Explore the amount of dust inhabitable zones.
Determining if such a disk interferes with future planet finding missions (dust-scattered starlight causes noise in images of exoplanets^[2]).
Determine composition of material delivered to planets: icy and organic molecule-rich particles are important for life.^[3]
Determine fraction of massive planets on large orbits.
Observe howprotoplanetary disks make Solar System-like architectures.
Constraingiant planets' composition by measuring their reflectivity.^[4]EXCEDE would be the first to image (giant) exoplanets distances from their stars similar to ours (0.5-7AU).^[5]
