Multiplicity Survey of 20 Y Dwarfs with NIRCam Kernel Phase Interferometry — Following the JWST ERS and Cycle 1 GO Announcement of Opportunity published on June 14, 2021, the CSA is providing funding via a Grant Agreement to the university to conduct their research using the JWST data. 

The JWST, with its unrivalled sensitivity at 5 microns where brown dwarfs are least faint, will search for companions orbiting around the 20 coldest and presumably least massive brown dwarfs in an effort to determine at what rate these stars form with companions. That multiplicity rate can provide important clues to understand the star formation process as a whole, from massive to low-mass stars.
