The morphology of the HD 163296 jet as a window on its planetary system

Abstract: Context. HD 163296 is a Herbig Ae star which drives a bipolar knotty jet with a total length of ∼6000 au. Strong evidence exists that the disk of HD 163296 harbors planets. Studies have shown that the presence of companions around jet-driving stars could affect the morphology of the jets. This includes a 'wiggling' of the jet axis and a periodicity in the positions of the jet knots. Aims. In this study we investigate the morphology (including the jet width and axis position) and proper motions of the HD 163296… Show more

“…However, the velocities of the stellar jet have values ranging over 100 km s −1 ; in contrast, the C I feature is spread over only a couple kilometers per second. More importantly, the jet observed to the SW of the disk is blueshifted (Gunther et al 2013;Ellerbroek et al 2014;Xie et al 2021;Kirwan et al 2022), which is expected given the orientation of the HD 163296 disk in the sky, i.e., the NE side being the closest to us ). On the contrary, the C I feature that we observe at ∼50 au toward the SW is redshifted.…”
