Johns Krull Física, Astronomía y Matemáticas Stars: Pre Main Sequence Accretion : Disks Stars: Magnetic Fields High resolution spectroscopy of photospheric absorption lines, particularly in the infrared, reveals the presence of magnetic fields on T Tauri stars. High resolution circular spectropolarimetry provides strong constraints on the geometry of the large scale stellar magnetic fields believed to play a crucial role in controlling accretion onto, and winds from, these stars. We review the latest measurements of T Tauri magnetic fields, which show convincing evidence that stellar magnetic fields do control accretion onto the star. We then compare the measurements with expectations from theory. 2003 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57101810 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.18 |
