A Streamer Driving Misalignment in the Circumtriple Disk of GW Ori

GW Orionis is a triple stellar system with a disk featuring three misaligned dust rings.

GW Orionis is a triple stellar system with a disk featuring three misaligned dust rings. We present ALMA molecular line data of CO isotopologues, revealing a streamer feeding the disk in $^{12}$CO and $^{13}$CO. Through multi-pointing observations, we find the streamer extends…
