30 Dec 2004 | | Subject: | astro-ph | | Affiliation: | Radiophysical Research Institute, Russia, Nizhnij Novgorod State University, Russia, Special Research Bureau, Russia, Urumqi Astronomical Observatory, China, Central Astronomical Observatory, Russia, DRAO, Canada, IRA, Noto, Italy | | Abstract: | This work devotes to investigations of solar corona and solar wind plasma by the method of radio probing with using of very long baseline interferometry (VLBI). We performed the theoretical calculation of power spectrum of interferometric response to radio source emission, passed through the turbulent medium. Data of theoretical analysis are compared with results of international VLBI experiments on investigations of solar wind plasma. The observations were realized in 1998, 1999, 2000 with participation of radio telescopes, included at Low Frequency VLBI Network (LFVN): Bear Lakes (RT-64, Russia), Puschino (RT-22, Russia), Urumqi (RT-25, China), Noto (RT-32, Italy), Shanghai (RT-25, China) and others. Preprocessing was carried out with using of S2 correlator at Penticton (Canada). Post processing of experimental data was performed at RRI (Russia) and was aimed to obtain value of solar wind velocity and index of spatial spectrum of electron density fluctuations. | | Source: | arXiv, astro-ph/0412696 | | Services: | Forum | Review | PDF | Favorites | |
