The solar wind in the Venus ionosheath: examination of mass loading and frictional phenomena
Contenido principal del artículo
Resumen
Los datos de plasma de los vehículos Marinero 5, Venera 9 y 10, y Pionero Venus, son utilizados en un estudio comparativo del viento solar en la región exterior a la ionosfera del planeta Venus. La evidencia experimental indica que atrás del frente de choque, en la vecindad del terminador, el viento solar experimenta una desaceleración repentina. Se discuten las implicaciones de este cambio de velocidad en relaci6n con los efectos de procesos químicos (asimilación de masa y colisiones de intercambio de carga) y fenómenos de fricción. Se concluye que los primeros no son suficientes para explicar la manera en que el viento solar se desacelera en esa regi6n, y que cerca del terminador existe un fuerte acoplamiento entre el viento solar y el plasma ionosférico.
