JWST/MIRI Detection of [Ne v], [Ne vi], and [O iv] Wind Emission in the O9 V Star 10 Lacertae

JWST/MIRI Detection of [Ne v], [Ne vi], and [O iv] Wind Emission in the O9 V Star 10 Lacertae

We report the detection of broad, flat-topped emission in the fine-structure lines of [Ne v ], [Ne vi ], and [O iv ] in mid-infrared spectra of the O9 V star 10 Lacertae obtained with James Webb Space Telescope/Mid-Infrared Instrument. Optically thin emission in these high ions traces a hot, low-den...
