    The opto-mechanical and -thermal performance of the telescope is crucial to attain high-quality solar observations and we present a study of optical and structural design of the large aperture space solar telescope, together with conceptual design of its accompanying focal plane instruments: wide-band and narrow-band filtergraphs and a spectro. Here the plasma is not bound and flows outwards, forming the solar wind. When followed back to the inner corona, one notes that most of the solar wind originates from coronal holes, regions of low density, nearly vertical magnetic fields, and conspicuous darkness in soft X-ray pictures (see Fig. ).5/5(6).

      On the Relationship Between High Speed Solar Wind Streams and Radiation Belt Electron Fluxes. NASA Technical Reports Server (NTRS) Zheng, Yihua. Both past and recent research results indicate that solar wind speed has a close connection to radiation belt electron fluxes [e.g., Paulikas and Blake, ; Reeves et aI., ]: a higher solar wind speed is often . The slow solar wind (~ km/s) permeates the plane of the ecliptic during most of the solar cycle so it is important to Earth’s space environment. The slow solar wind shows different mass flux and composition than the fast wind, consistent with confined plasma in the solar corona.

Get this from a library. A study of shock-associated magnetohydrodynamic waves in the solar wind. [Steven R Spangler; United States. National Aeronautics and Space Administration,]. The high speed streams of solar wind from coronal holes show that there is substantial heating, of 1 – 2 × 10 5 ergs/cm 2 sec, beyond the sonic point (r≳5R ˙) in the wind, which can come only from the dissipation by thermal conduction of long period (≳10 2 sec) MHD waves from subphotospheric convection.

Although the Alfven wave flux. Magnetohydrodynamic (MHD) turbulence is commonly observed in the solar wind. Nonlinear interactions among MHD waves are likely to produce finite correlation of the wave phases. Unfortunately, this book can't be printed from the OpenBook.

When these two terms on the right-hand side of Eq.(26) are not balancing each other, then the dynamics of the kinetic Alfven waves will be governed by the competition between these two terms.
