Raga Física, Astronomía y Matemáticas MAIN SEQUENCE STARS: PRE ISM: JETS AND OUTFLOWS ISM: INDIVIDUAL (HH 111) We present long-slit spectroscopic observations of the HH 111 jet obtainedwith the 4.2 m William Herschel Telescope. We have obtained spectra for slitpositions along and across the jet axis, in order to search for radial velocity, electrondensity and excitation variations across the jet. We have detected faint emissionacross knots HH 111 D and F, extending to large ( 15``) distances from the flowaxis. This extended emission shows a radial velocity stratification, with higherradial velocities on the jet axis and lower velocities away from the axis. Knot D hasa low central electron density surrounded by material with higher electron densities,while the electron density is approximately constant across knot F. We argue thatthe extended emission and the radial velocity variations observed across the HH 111flow are compatible with a jet beam with a transverse gradient in velocity or witha jet which is entraining low velocity material. 2001 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57137203 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.2 Vol.37 |
