- The orion nebula: an elephant for the blind C. R. O`Dell Física, Astronomía y Matemáticas NAMICS STARS: WOLF{RAYET PLANETARY NEBULAE: GENERAL ISM: ABUNDANCES { ISM: KINEMATICS AND DY Preliminary results from high resolution spectroscopy for a selected sample ofplanetary nebulae with WR nucleus or weak{emission line star (wels) are presented.The observed objects spread over a wide range in stellar characteristics: early andlate [WC]{type stars and wels have been selected. Nebular densities and temperatures,as well as ionic and total abundances and expansion velocities, have beenderived. The results are used to perform a statistical study of the objects in orderto nd possible relationships among the di erent stellar and nebular parametersand to analyze the e ect of the WR wind on the nebular shell. 2001 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57101004 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
