太阳作为恒星:SoHO的13年

The Sun as a Star: 13 years of SoHO

R. A. Garcia

摘要:

最著名的类似太阳振荡的恒星是太阳。在过去的14年中,欧空局/美国航天局太阳和日光层观测站(SoHO)一直在从拉格朗日点L1观测这颗恒星,取得了巨大的成功。在船上放置的11个仪器中,有3个是专门用于日震学的:GOLF,VIRGO和MDI。前两个观测太阳作为一个恒星通过整合的速度或强度信号的可见太阳光盘到一个单一的点。因此,它们类似于在星震学中进行的任何其他观测。在这次审查中,我将介绍任务期间获得的最重要的结果,关于太阳被视为一颗恒星,以及这些结果如何演变我们对恒星内部的想法。

英文摘要:

The best known Solar oscillation-like star is the Sun. During the last 14 years, the ESA/NASA Solar and Heliospheric Observatory (SoHO) has been continuously observing this star from the Lagrange point L1 with an enormous success. Among the 11 instruments placed onboard, 3 of them are dedicated to helioseismology: GOLF, VIRGO and MDI. The first two observe the Sun as a star by integrating the velocity or intensity signal of the visible solar disk into a single point. They are thus similar to any other observation done in asteroseismology. During this review I will present the most important results obtained during the mission concerning the Sun seen as a star and how this results have evolved our thoughts of the inside of our star.
