چکیده انگلیسی
We make the following predictions: (1) The secular light curve (SLC) of comet 67P/Churyumov-Gerasimenko exhibits a photometric anomaly in magnitude that is present in 1982, 1996, 2002 and 2009. Thus it must be real. We interpret this anomaly as a topographic feature on the surface of the nucleus that may be a field of debris, a region made only of dust or an area of solid stones but in any case it is depleted in volatiles. We predict that images taken by spacecraft Rosetta will show a region morphologically different to the rest of the nucleus, at the pole pointing to the Sun near perihelion. (2) Comet C/2012 K1 PANSTARRS exhibits the same Slope Discontinuity Event (SDE)+magnitude dip after the event than other comets listed in Table 1 most of which disintegrated. This group includes comet C/2012 S1 ISON. Thus, it is reasonable to expect that this comet may disintegrate too. The probability of disintegration of this comet is 27%. (3) Comet C/2013 V5 Oukaimeden exhibits the same SDE+standstill signature exhibited by other comets in Table 1. We predict that there is a 93% probability that this comet will disintegrate. (4) Another purpose of this work is to present evidence to conclude that the SLCs have predictive power.
