Issue Date: | 2024 | Journal: | ASTRONOMY & ASTROPHYSICS | Number: | 683 | First Page: | L15 | Abstract: | We report new Very Large Array high-resolution observations of the radio jet from the outbursting high-mass star S255IR NIRS 3. The images at 6, 10, and 22.2 GHz confirm the existence of a new lobe emerging to the SW and expanding at a mean speed of ~285 km s-1, about half as fast as the NE lobe. The new data allow us to reproduce both the morphology and the continuum spectrum of the two lobes with the model already adopted in our previous studies. We conclude that in all likelihood both lobes are powered by the same accretion outburst. We also find that the jet is currently fading down, recollimating, and recombining. | URI: | http://hdl.handle.net/20.500.12386/35553 | URL: | https://www.aanda.org/articles/aa/full_html/2024/03/aa49288-24/aa49288-24.html https://api.elsevier.com/content/abstract/scopus_id/85188469448 |
