JWST NIRCam survey of 11 globular clusters detects multiple populations in low-mass stars, showing discrete sequences in some clusters and continuous distributions or helium/oxygen variations in others, plus an M-dwarf gap in NGC 104.

abstract
In this paper we demonstrate that the puzzling bright peak in the luminosity function of the white dwarf (WD) cooling sequence of NGC6791 can be naturally accounted for if ~34% of the observed WDs are WD+WD binary systems.

Globular Clusters in the Time of the JWST. I. Survey Design and First Results on Multiple Populations and Beyond
JWST NIRCam survey of 11 globular clusters detects multiple populations in low-mass stars, showing discrete sequences in some clusters and continuous distributions or helium/oxygen variations in others, plus an M-dwarf gap in NGC 104.
