Tagger Física, Astronomía y Matemáticas mag plasmas Accretion instabilities galaxy: center In this paper I review progress made in the last few years in explaining the low-frequency QPO of microquasarsby the Accretion-Ejection Instability, and how this may guide us in understanding the short and long termvariability of these sources. I then turn to another, closely related instability, which also relates to diskoseismologic models. I show how it might apply to explain the high-frequency QPO of microquasars, and the flares in Sgr A*, the massive black hole at the Galactic Center. 2007 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57102705 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.27 |
