行星际闪烁[Interplanetary Scintillation] [2005-10-25]
iamet 发表在 ¤〖天文〗
| | The Sun emits "blobs" of plasma (known as the solar wind). Depending on the geometry, rays through different blobs can be focused to a single point. A sort of "twinkling" known as interplanetary scintillation can therefore be observed at 1 m wavelength. This technique works only at low frequencies on the order of 1 m (327 MHz). |
