- В работе оценивается возможность эффективной генерации радиоизлучения в области головной ударной волны экзопланет типа “горячий юпитер”. В качестве источника энергичных электронов предложен дрейфовый механизм ускорения на квазипоперечной ударной волне. Отраженные от ударной волны и ускоренные ею электроны распространяются в сравнительно плотной плазме звездного ветра и генерируют плазменные волны, поэтому плазменный механизм рассмотрен в качестве источника радиоволн. На примере головной ударной волны горячего юпитера HD 189733b оценены параметры пучка энергичных электронов, плазменных волн и частота генерируемого радиоизлучения. Выполнена энергетическая оценка области параметров звездного ветра, для которой возможна регистрация радиоизлучения от головной ударной волны экзопланеты HD 189733b современными астрономическими средствами.
