从太阳和恒星地震学看低质量恒星的内旋

The internal rotation of low-mass stars from solar and stellar seismology

G. Buldgen, P. Eggenberger

摘要:

由于日震学和星震学,测量太阳和恒星内部自转的可能性对恒星内部的水动力学和磁流体动力学过程提供了巨大的限制。了解恒星内部角动量传输的过程至关重要,因为它们也会影响化学物质的传输,从而影响恒星的演化。在这里,我们提出了一些关键的结果,在这两个领域,以及如何详细的地震分析可以提供严格的限制,在低质量恒星内部的角动量输运的物理,并可能排除一些候选人。

英文摘要:

The possibility of measuring the internal rotation of the Sun and stars thanks to helio- and asteroseismology offers tremendous constraints on hydro- and magnetohydrodynamical processes acting in stellar interiors. Understanding the processes responsible for the transport of angular momentum in stellar interiors is crucial as they will also influence the transport of chemicals and thus the evolution of stars. Here we present some of the key results obtained in both fields and how detailed seismic analyses can provide stringent constraints on the physics of angular momentum transport in the interior of low mass stars and potentially rule out some candidates.
