Spiral Density Waves in a Young Protoplanetary Disk [PDF]
, 2016 Gravitational forces are expected to excite spiral density waves in protoplanetary disks, disks of gas and dust orbiting young stars. However, previous observations that showed spiral structure were not able to probe disk midplanes, where most of the ...
