标题： Characterization of horizontal flows around solar pores from high-resolution time series of images

摘要： 尽管有越来越多的证据将沟流和埃弗谢德流与半影纤维联系起来，但关于围绕本影核和孔周围是否存在沟流仍没有明确的共识，该争论仍在继续。 太阳孔似乎是一个适合测试沟流-半影关系的情景，因为它能证明本影与周围光球中的对流等离子体之间的直接相互作用，中间没有任何中间结构。 本研究基于高分辨率的地基和卫星观测数据对太阳孔进行了研究。 局部相关跟踪技术被应用于不同持续时间的时间序列，以分析几个太阳孔周围的水平流动。 我们的结果表明，从不同的太阳孔观测中计算出的流动彼此之间具有相干性，并显示出爆炸事件在孔周围 granulation 中的决定性和总体影响。 我们没有发现任何围绕太阳孔的类似沟流的流动迹象，而是发现了一个明显定义的流入区域围绕着它们。 本研究通过这一发现进一步加强了沟流与与半影纤维相关的流动之间的联系。 显示英文摘要

摘要： Though there is increasing evidence linking the moat flow and the Evershed flow along the penumbral filaments, there is not a clear consensus regarding the existence of a moat flow around umbral cores and pores, and the debate is still open. Solar pores appear to be a suitable scenario to test the moat-penumbra relation as evidencing the direct interaction between the umbra and the convective plasma in the surrounding photosphere, without any intermediate structure in between. The present work studies solar pores based on high resolution ground-based and satellite observations. Local correlation tracking techniques have been applied to different-duration time series to analyze the horizontal flows around several solar pores. Our results establish that the flows calculated from different solar pore observations are coherent among each other and show the determinant and overall influence of exploding events in the granulation around the pores. We do not find any sign of moat-like flows surrounding solar pores but a clearly defined region of inflows surrounding them. The connection between moat flows and flows associated to penumbral filaments is hereby reinforced by this work.
