| contents | THE EXO-PLANETARY SYSTEM OF 55 CANCRI AND THE TITIUS-BODE LAW Arcadio Poveda Patricia Lara Física, Astronomía y Matemáticas Planetary systems stars: individual (55 Cancri) planets and satellites: general The recent discovery of a fth planet bound to 55 Cancri (Fischer et. al 2007) motivated us to investigate if this exo-planetary system ts some form of the Titius-Bode (TB) law. We found that a simple exponential TB relation reproduces very well the ve observed major semi-axis, provided we assign the orbital n = 6 to the largest a. This way of counting leaves empty the position n = 5, a situation curiously reminiscent of TB law in our planetary system, before the discovery of Ceres. The application of an exponential TB relation to 55 Cancri allows us to predict the existence of a planet at a 2:0 AU with a period of P 1130 days located within the large gap between a = 0:781 AU (P = 260 days) and a = 5:77 AU (P = 5218 days). With less certainty, we also predict a seventh planet at a 15 AU, with P 62 years. 2008 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57116170013 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.34 |
