   <abstract xml:lang="ru">
    <p>В обзоре излагается современное состояние теории короткопериодных УНЧ-волн, учитывающей наличие в плазме магнитосферы примеси тяжелых ионов (ионов, масса которых существенно превышает массу протонов). Наличие тяжелых ионов влияет на спектр и характеристики распространения волн диапазона Рс1. Рассмотрены элементы теории квазипродольных и квазипоперечных короткопериодных УНЧ-волн. Квазипродольные ионно-циклотронные волны, как правило, имеют левую круговую поляризацию. Квазипоперечные ионно-ионные гибридные волны имеют линейную поляризацию и могут быть полоидальными и торои-дальными. Рассмотрена теория экваториального резонатора для волн Рс1, размер которого определяется концентрацией тяжелых ионов. В радиальном направлении волны могут быть заперты в окрестности плазмопаузы или в области локального минимума плотности тяжелых ионов. Рассмотрены размеры экваториального резонатора при произвольных значениях компонент волнового вектора. Отмечено, что ионно-ионные гибридные волны в отличие от альфвеновских волн имеют большую продольную компоненту магнитного поля.</p>

    <p>The review considers the current state of the theory of short-period ULF waves in plasma with admixture of heavy ions (ions whose mass significantly exceeds the mass of protons). The presence of heavy ions influences the spectrum and propagation characteristics of waves in Pc1 range. We examine elements of the theory of quasi-parallel and quasi-perpendicular short-period ULF waves. It is usually suggested that quasi-parallel ion-cyclotron waves have a left circular polarization. Quasi-perpendicular ion-ion hybrid waves have linear polarization and can be poloidal and toroidal. We discuss the theory of an equatorial resonator for Pc1 waves and determine its size from the density of heavy ions. In the radial direction, the waves can be locked in the vicinity of the plasmapause or in the region of a local minimum in the density of heavy ions. The equatorial resonator for arbitrary values of the wave vector components is considered. We note that ion-ion hybrid waves, in contrast to Alfvén waves, have a large parallel component of the magnetic field.</p>
