Henney Física, Astronomía y Matemáticas UAL (M42) H II REGIONS ISM: INDIVID INTERFEROMETRY STARS: CIRCUMSTELLAR MATTER We re{examine radio observations of compact sources in the core of the Orionnebula and nd that 70% of the sources correspond to known proplyds. For allof these sources, including many that have been previously classied as variableand non{thermal, the radio ux between 1.5 and 86 Ghz is fully accounted for bythermal free{free emission from the photoevaporation ow. We therefore suggestthat many of the proposed Orion FOXES are in fact EIDERS, and that theirapparent variability reects observational diculties in detecting the lower surface{brightness portions of the proplyds. The PIGs turn out to be extinct in Orion, andthe hybrid creatures that we dub PANTHERS (Proplyds Associated with Non{THErmal Radio Sources) remain elusive. 2001 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57101047 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) Vol.10 |
