Palaeolithic extinctions and the Taurid Complex

“…The pre‐entry orbital elements of the body are shown in Table 2, along with those of asteroid Cuno and Comet Encke. The Tagish Lake fall has been identified with the μ‐Orionid fireball stream which, in turn, has been associated with (4183) Cuno (Terentjeva & Barabanov 2004), an asteroid belonging to the group of large NEOs which appear to be part of the Taurid Complex (Table 1). These generic relationships, along with the primitive nature of the Tagish Lake meteorite, suggest that it may be part of this Complex and that nanodiamonds are generally present in the progenitor comet.…”

“…Mathematical criteria while searching, of course, help to find required orbits, though these play a subsidiary role. The main role belongs to common sense [20]. We calculated values of Tisserand's constant C for all five objects (Table 1, 3) by formula: (where the perturbing planet is Jupiter, a -the asteroid semimajor axis, e -the asteroid eccentricity, i -the asteroid inclination, a j -the semimajor axis of the perturbing planet -Jupiter).…”

The investigation of meteorite stream using the Chinese historical records

“…Existences of the fireball streams have been established and investigated (Terentjeva 1990;Porubčan and Gavajdová 1994). Some researches indicated that the association between fireball streams and asteroids (Gavajdová 1995;Porubčan et al 2004) or cometoids (or comet like asteroids) (Terentjeva and Barabanov 2002). In contrast to meteor streams and fireball streams, there is a little literature (Spurný et al 2003) to discuss meteorite streams, because of rare meteorite events.…”
