慢脉动亚矮星B的光谱模式识别

Spectroscopic Mode Identification in Slowly Pulsating Subdwarf-B Stars

C. Schoenaers, A. E. Lynas-Gray

摘要:

模式识别对于任何意义上的星震学研究都是至关重要的。类似于光谱技术,诸如周期拟合和多色测光的方法不能提供非径向脉动的完整重建。我们提出了一种新的光谱模式识别方法,并测试它的时间序列的合成光谱适合脉动亚矮星B星。然后,我们将其应用于新发现的缓慢脉动的亚矮星-B星HD 4539。

英文摘要:

Mode identification is crucial for an asteroseismological study of any significance. Contrarily to spectroscopic techniques, methods such as period-fitting and multi-colour photometry do not provide a full reconstruction of non-radial pulsations. We present a new method of spectroscopic mode identification and test it on time-series of synthetic spectra appropriate for pulsating subdwarf-B stars. We then apply it to the newly discovered slowly pulsating subdwarf-B star HD 4539.
