Chinese Observations of Solar Spots

Seismology of solar spicules based on Hinode/SOT observations

Forty two years counting spots: Solar observations by D.E. Hadden during 1890–1931 revisited

We have recovered the sunspot observations made by David E. Hadden during 1890–1931 from Alta, Iowa. We have digitized the available data published by Hadden in different astronomical journals. This data series have been analyzed and compared with the standard sunspot number series. Moreover, we provide additional information on two great sunspot groups, previously not described, that originate...

Observations of Solar Coronal Magnetic

This review discusses methods for determining solar coro-nal magnetic elds, with an emphasis on radio measurements of eld strengths in solar active regions.

Observations of Solar-like Oscillations

There has been tremendous progress in observing oscillations in solar-type stars. In a few short years we have moved from ambiguous detections to firm measurements. We review the recent results, most of which have come from high-precision Doppler measurements. We also review briefly the results on giant and supergiant stars and the prospects for the future.
