Afanasév Física, Astronomía y Matemáticas ISM: SUPER NOVA REMNANTS TECHNIQUES: SPECTROSCOPIC ISM: INDIVIDUAL: CRAB NEBULA We present the spatially resolved optical spectroscopy of the 1200 2400 Crabpulsar neighbourhood in the range 4600 - 5700 A made with the Multipupil FiberSpectrograph at the 6 m telescope of the SAO RAS. The spectra exhibit blue{ andred{shifted strong [O III] and weaker H and He II emission lines with the shiftsand intensities varying with the position in the eld. They hint the presence of acone{like rotating structure centered at the pulsar position and oriented along thesymmetry axis of the compact, torus{like pulsar nebula seen in optical continuumand soft X{rays. The kinematic structure is most likely associated with the pulsarnebula. If so, the compact nebular rotates counter{clockwise with respect to itssymmetry axis, or the pulsar spin axis, and the estimated rotational velocity withincylindrical radii of several thousand AU from the pulsar is 2000{3000 km/s. 2001 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57101037 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 |
