为了帮助地面观测网和SoHO实验探测和识别太阳光谱中的低频p模和g模,我们研究了低阶(= 0 - 6)低频(100 - 2000 Hz)太阳振荡的性质。已经计算了一组太阳模型的p-和g-模式的频率与更新的物理。我们指出的具体性质的混合字符的振荡,在中心和外部层的显着幅度。我们分析了低频振荡对太阳参数的敏感性,如年龄,金属丰度和光度,以及各种物理过程,如对流核心过冲和太阳演化开始时的质量损失。我们估计了这些低频振荡分裂对地核自转的敏感性.
In order to help the detection and identification of low-frequency p- and g-modes in the solar spectrum observed by ground-based networks and SoHO experiments, we study the properties of low degree ('=0 - 6) low-frequency (100 - 2000 Hz) solar oscillations. The frequencies of p- and g-modes have been computed for a set of solar models with updated physics. We point out the specific properties of the oscillations of mixed character, with noticeable amplitude both in central and external layers. We analyze the sensitivity of low-frequency oscillations to solar parameters like age, metallicity and lumi- nosity, and to various physical processes, like convective core overshoot and mass loss during the beginning of solar evolu- tion. We estimate the sensitivity of the splittings of these low- frequency oscillations to the core rotation.
