Recently determined heavy element abundances 1-3 have led to significant changes in our understanding of the internal structure and constitution of the Sun. It turns out that the standard solar models calculated with the new abundances are significantly different from the helioseismic results which were in a good agreement with the previous solar models. Figure 1 shows the relative difference b...

Studies of the origin of coronal heating and acceleration of the solar wind invoke high-frequency Alfvén waves. Here we suggest a source for such waves associated with twisted magnetic loops emerging on the solar surface and reconnecting with the open field. We identify the loops with the ephemeral regions (small-scale bipoles) observed by ground-based instruments and by SOHO. To characterize t...
