红巨星的星震学
Asteroseismology of Red Giant stars
摘要：
类太阳振荡，即对流噪声随机激发的p模，现在已经在一些红巨星中观察到。与太阳中看到的模式相比，这些模式具有大振幅和长周期，使振荡具有吸引力的观测前景。然而，这些模式的低Q因子以及与低频背景上升有关的问题，对识别模式和确定相关的小行星地震参数提出了一些令人感兴趣的挑战。我们报告的分析程序，通过峰值装袋由我们的小组在伯明翰，和技术，以有力地确保这些不是一个产品的噪音。我还展示了用SMEI仪器从多年观测中提取的一些巨星的结果。
英文摘要：
Sun-like oscillations, that is p-modes excited stochastically by convective noise, have now been observed in a number of Red Giant stars. Compared to those seen in the Sun, these modes are of large amplitude and long period, making the oscillations attractive prospects for observation. However, the low Q-factor of these modes, and issues relating to the rising background at low frequencies, present some interesting challenges for identifying modes and determining the related asteroseismic parameters. We report on the analysis procedure adopted for peak-bagging by our group at Birmingham, and the techniques used to robustly ensure these are not a product of noise. I also show results from a number of giants extracted from multi-year observations with the SMEI instrument.
