Chené Física, Astronomía y Matemáticas Wolf Rayet stars winds stars rotation outflows stars The rotational velocity of Wolf-Rayet (WR) stars cannot be measured directly from "classical" photospheric absorption lines. However, it can be infered from periodic large-scale wind variability.Afteridentifying a list of WR stars presenting large-scale spectral variability, we have monitored 3 of them intensively. The period of these stars, along with the already published periods of WR6 and WR134, lead to a rotational velocity for WR stars in the range of 10-60 km s-1. 2008 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57116159010 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.33 |
