标题： Polarisation of decayless kink oscillations of solar coronal loops

摘要： 太阳日冕中磁环无衰减的扭振可能为解开日冕和恒星日冕加热这一谜题提供答案。 这些振荡的偏振为我们提供了关于其激发机制和能量供给的独特信息。 然而，明确确定偏振仍然具有挑战性。 在这里，我们展示了从两条非平行视线（相距约104\textdegree ）同时检测到一个4分钟无衰减的扭振，这是太阳轨道器上的高分辨率成像仪与太阳动力学观测台上的大气成像组件的独特组合提供的。 观测结果揭示了振荡的水平或弱倾斜线性偏振。 这一结论基于将观测结果与各种类型扭振偏振的前向建模结果进行比较。 所揭示的偏振支持这些振荡由准定常流维持，因此可能为日冕加热提供能量。 显示英文摘要

摘要： Decayless kink oscillations of plasma loops in the solar corona may contain an answer to the enigmatic problem of solar and stellar coronal heating. The polarisation of the oscillations gives us a unique information about their excitation mechanisms and energy supply. However, unambiguous determination of the polarisation has remained elusive. Here, we show simultaneous detection of a 4-min decayless kink oscillation from two non-parallel lines-of-sights, separated by about 104\textdegree, provided by unique combination of the High Resolution Imager on Solar Orbiter and the Atmospheric Imaging Assembly on Solar Dynamics Observatory. The observations reveal a horizontal or weakly oblique linear polarisation of the oscillation. This conclusion is based on the comparison of observational results with forward modelling of the observational manifestation of various kinds of polarisation of kink oscillations. The revealed polarisation favours the sustainability of these oscillations by quasi-steady flows which may hence supply the energy for coronal heating.
