Shedir是可变的吗?

Is Shedir Variable?

Samuel J. George, Ian R. Stevens, Steven A. Spreckley

摘要:

在现代摄影和CCD观测之前,仙后座α星被标记为变星,尽管这种变化在现代仪器中还没有被发现。我们提出了一个分析的3年的高精度空间测光的怀疑变星α仙后座,获得了宽带太阳质量喷射成像仪(SMEI)仪器上的科里奥利卫星。在3年的观测中,这颗恒星似乎没有显示出任何显著的变化。此外,依巴谷历元测光附件的数据显示没有显着的变化。

英文摘要:

Before the age of modern photographic and CCD observations alpha Cassiopeiae was labelled as a variable star, though this variability has not been seen with modern instrumentation. We present an analysis of 3 years of high precision space-based photometric measurements of the suspected variable star alpha Cassiopeiae, obtained by the broad band Solar Mass Ejection Imager (SMEI) instrument on board the Coriolis satellite. Over the 3 years of observations the star appears to not show any significant variability. Also, data from the Hipparcos epoch photometry annex shows no significant variability.
