Giant planet formation traps dust in pressure bumps and planetesimal formation converts dust to larger bodies, making evolved disk masses appear low as a natural outcome of these processes, with models matching observations best for initial disk masses of 4-7% solar mass.
ALMA observed 3933 independent coordinates in nearby star-forming regions for disks and planet formation, analyzed by sky location, frequency coverage, exposure time, spectral lines, and angular resolution.

A giant solution to the disk mass budget problem of planet formation
Giant planet formation traps dust in pressure bumps and planetesimal formation converts dust to larger bodies, making evolved disk masses appear low as a natural outcome of these processes, with models matching observations best for initial disk masses of 4-7% solar mass.
