    Free core nutation: direct observations and resonance effects

  • Original language description

    Based on the combined solution of the observed celestial pole offsets by VLBI and GPS, a temporary change of the period of Free Core Nutation is found. However, from the observed forced nutation terms follows that this period is very stable. The diference is explained by additional excitation by the ocean and atmosphere.

    Volná mutace jádra: přímá pozorování a resonanční efekty

  • Czech description

    Na základě kombinovaného šíření pozorovaní odchylek nebeského pólu pomocí VLBI a GPS je spočtena časová změna periody volné nutace jádra. Z pozorovaných vynucených členů nutace naopak vyplývá, že tato perioda je velice stálá. Nesoulad se vysvětluje dodatečnou excitací oceánem a atmosférou.
