Gas Dynamics in the Herbig Ae Star HD 163296 in 2024
Original language description
We observed the Herbig Ae star HD 163296 over 9 nights in 2024. On 4 of the nights, the He i line at 1.083 μm exhibited a profile rarely seen in the star. Rather than the typical P Cygni profile indicating a net gas outflow, the profile consisted of a deep absorption line with weak emission peaks on either side. These seem to be consistent with either an outflowing bipolar jet, a circular ring of gas orbiting close to the star, and/or accretion columns connecting the inner disk to the star. Given the history of the ejection of Herbi-Haro object in the star's bipolar jets, these observations should coincide with the very beginning of the ejection event. Coordinated observations with multiple observing techniques over the next decade are warranted.
