Spicules and Alfvén Waves? <br />
@ Dome C better than HiNODE: <br />
- lines’ width <br />
- multi-wavelength spectroscopy <br />
HiNODE Ca II H<br />
3968 filter:<br />
spicules at the<br />
limb of the Sun<br />
are seen to form<br />
rapidly propelling<br />
matter upward,<br />
while moving<br />
transversely to<br />
their own long<br />
axis during their<br />
short lifetimes.<br />
These transverse<br />
motions may be<br />
caused by Alfvén<br />
waves and would<br />
have enough<br />
power to drive the<br />
solar wind.
