太阳黑子半影区对流的最新证据

Recent Evidence for Convection in Sunspot Penumbrae

G. B. Scharmer

摘要:

而在过去的15年中,半影模型已成功地解释Evershed流动和磁场倾斜变化的通量管,缺乏这些模型之间的联系和对流过程需要解释半影辐射热通量一直令人不安。我们报告最近的观测和理论证据,挑战通量管的解释,并得出结论,半影对流结构的起源是翻转对流。

英文摘要:

Whereas penumbral models during the last 15 years have been successful in explaining Evershed flows and magnetic field inclination variations in terms of flux tubes, the lack of contact between these models and a convective process needed to explain the penumbral radiative heat flux has been disturbing. We report on recent observational and theoretical evidence that challenge flux tube interpretations and conclude that the origin of penumbral filamentary structure is overturning convection.
