标题： SRVs in the Solar Neighbourhood

摘要： 周期-光度序列已被证明存在于大麦云的半规则变星（SRVs）（Wood等，1999），银河系核球（Glass和Schultheis，2003）以及其他地方。显然，拥有这些关系的绝对（三角测量）校准将非常有用。本文研究了这些序列是否可以在太阳邻域的M型巨星半规则变星中看到。还讨论了这些恒星的质量损失现象及其与周期和光谱子类型的关系。 显示英文摘要

摘要： Period-luminosity sequences have been shown to exist among the Semi-Regular Variables (SRVs) of the Magellanic Clouds (Wood et al, 1999), the Bulge of the Milky Way galaxy (Glass & Schultheis, 2003) and elsewhere. It would clearly be useful to have absolute (trigonometric) calibrations of these relations. This paper investigates whether the sequences can be seen among the M-type giant SRVs of the solar neighbourhood. Mass loss phenomena among these stars and their dependence on period and spectral sub-type are also discussed.
