Characterization of the Fireballs Detected by MOROI in Romania

The meteors recorded by all-sky cameras in Romania were analyzed in a paper recently published in The Astrophysical Journal. In this paper we study the meteors detected by the FRIPON network in Romania in the time period January 2021 – April 2022 with the use of the MOROI all-sky cameras. We focus on the events with noticeable deceleration (V_f/V_0<0.8 , where V_f is the velocity of the meteoroid at the end of the luminous trajectory and V_0 is the initial velocity of the meteoroid). We characterize the fireball events with the use of the the ballistic coefficient α and the mass-loss parameter β. Based on this analysis, the events are classified in three categories: 1) meteoroids that are likely to produce meteorites, 2) meteoroids that can possibly produce meteorites, 3) meteoroids that are unlikely to produce meteorites. We computed the entry and final mass of each event. We identified a meteoroid that is likely to produce a meteorite on the ground and we analysed its past dynamical evolution. The article is available in Open Access.
