On the surface structure of sunspots
Franz, M.
A precise knowledge of the surface structure of sunspots is essential to construct adequate input models for helioseismic inversion tools. % and to gain information about the subsurface structure of sunspots. We summarize our recent findings about the velocity and magnetic field in and around sunspots using HINODE observation. To this end we quant…
Charge-exchange emission in the starburst galaxies M82 and NGC3256
Ranalli , P.
Charge-exchange (CE) emission produces features which are detectable with the current X-ray instrumentation in the brightest near galaxies. We describe these aspects in the observed X-ray spectra of the star forming galaxies M82 and NGC 3256, from the Suzaku and XMM-Newton telescopes. Emission from both ions (O, C) and neutrals (Mg, Si) is recogni…
Suzaku observations of charge exchange emission from solar system objects
Futaana, Y.; Mitsuda, K.; Porter, F. S. +9 more
Recent results of charge exchange emission from solar system objects observed with the Japanese Suzaku satellite are reviewed. Suzaku is of great importance to investigate diffuse X-ray emission like the charge exchange from planetary exospheres and comets. The Suzaku studies of Earth's exosphere, Martian exosphere, Jupiter's aurorae, and comets a…
