摘要
本文对恒星黑子的观测方法和结果作了综合评述。介绍了恒星黑子温度的多色测光测定方法；黑子大小、温度和分布情况的测光畸变波黑子模型解，和高信噪比谱线轮廓多普勒成像方法；以及黑子寿命观测统计方法等的基本原理和研究进展。对已取得的有关恒星黑子的观测分析结果作了概括，与太阳典型黑子情况作了对比，并对恒星黑子的巨黑子、极区黑子以及长寿命黑子特殊性作了讨论。对需要进一步观测研究的问题作了总结。
In this paper a review of the observational aspects of stellar spots is presented.The basic methodology and principles of measuremellts of spot parameters in the chromospherically active binary systems are described, which include the direct estimation of spot temperature by the V-I index in multi-color photometry, the solution of thedistorted light curve based on assumed circular spot model, alld the Doppler imaging of spots from the high S/N spectroscopy. The general chaxacteristics of starspots obtained by recent observations as well as the statistic studies are summed up. In comparison with typical solar spots, three distinct features of starspots, huge area, long life-time and the possibility for them to emerge in polar region, have given a striking challenge to the solar dynamo theory. A short discussion is also made on the further understanding of starspots by observations in the furture
