    The Carancas meteorite impact - Encounter with a monolithic meteoroid

  • Original language description

    The formation of a 13-m wide impact crater by a stony meteorite near Carancas, Peru, on September 15, 2007 was an unexpected event. Stony meteoroids usually disintegrate in the atmosphere in many pieces, each landing at low velocity. We present examplesof well-observed fireballs, which have all experienced atmospheric fragmentation. Using a simple model, we find that the Carancas meteoroid may have avoided fragmentation, if its strength was 20-40 MPa; such a strength would be comparable to the tensilestrength of stony meteorites, but is higher than the strength of other observed meteoroids. We conclude that Carancas was a rare example of a monolithic meteoroid that was free of internal cracks.

    Dopad meteoritu Carancas ? srážka s monolitickým meteoroidem

  • Czech description

    Vytvoření třináctimetrového kráteru kamenným meteoritem poblíž obce Carancas v Peru 15. září 2007 byla nečekaná událost. Kamenné meteoroidy se obvykle rozpadají v atmosféře na mnoho kusů, z nichž každý dopadne malou rychlostí. Uvádíme příklady podrobně pozorovaných bolidů a u každého z nich došlo k atmosférické fragmentaci. Pomocí jednoduchého modelu jsme zjistili, že meteoroid Carancas se nemusel rozpadnout, pokud jeho pevnost byla 20-40 MPa. Tato pevnost je srovnatelná s pevností v tahu kamenných meteoritů, ale je vyšší než pevnost ostatních pozorovaných meteoroidů.
