*Ryuki Hyodo¹, Shigeru Ida² (1.JAXA, 2.ELSI)

Keywords:planetesimal formation, planet formation, protoplanetary disks

In this talk, planetesimal formation around the snow line is discussed. We also report a new mechanism, the "no-drift" runaway pile-up, that leads to a runaway accumulation of pebbles in protoplanetary disks.

These new findings are discussed in the following papers:
