Bangs and meteors from the quiet comet 15P/Finlay
Original language description
Jupiter-family comet 15P/Finlay has been reportedly quiet in activity for over a century but has harbored two outbursts during its 2014/2015 perihelion passage. Here we present an analysis of these two outbursts using a set of cometary observations. The outbursts took place between 2014 December 15.4-16.0 UT and 2015 January 15.5-16.0 UT as constrained by ground-based and spacecraft observations. We find a characteristic ejection speed of V-0 = 300-650 m s(-1) for the ejecta of the first outburst and V-0 = 550-750 m s(-1) for that of the second outburst using a Monte Carlo dust model. The mass of the ejecta is calculated to be M-d = (2-3) x 10(5) kg for the first outburst and M-d = (4-5) x 10(5) kg for the second outburst, which. corresponds to less than 10(-7) of the nucleus mass.
