论文摘要

在整个太阳大气中通常观察到慢波。假设通量管近似薄,在Costa等人中获得了从Photosphere到Corona的慢模型磁性磁性磁性波的截止周期。 (2018)。但是,在该论文中,在恒定压力下的特定热系数中的错别字$ c _ {\ mathrm {p}} $值导致截止计算的不一致,这仅在过渡区域很重要。由于该区域的突然变化,还会发生平均原子重量的变化(大约两倍),但出于简单目的而在分析模型中经常被忽略。在本文中,我们重新审视了Costa等人中磁性磁性波的截止时期的计算。 (2018)通过考虑具有温度曲线的静静态平衡中的大气,其中包括平均原子重量的变化以及上述不一致的校正。此外,我们表明在分析上获得的截止周期与在特定活性区域观察中测得的相应时期一致。

Slow waves are commonly observed on the entire solar atmosphere. Assuming a thin flux tube approximation, the cut-off periods of slow-mode magneto-acoustic-gravity waves that travel from the photosphere to the corona were obtained in Costa et al. (2018). In that paper, however, a typo in the specific heat coefficient at constant pressure $c_{\mathrm{p}}$ value led to an inconsistency in the cut-off calculation, which is only significant at the transition region. Due to the abrupt temperature change in the region, a change of the mean atomic weight (by a factor of approximately two) also occurs, but is often overlooked in analytical models for simplicity purposes. In this paper, we revisit the calculation of the cut-off periods of magneto-acoustic-gravity waves in Costa et al. (2018) by considering an atmosphere in hydrostatic equilibrium with a temperature profile, with the inclusion of the variation of the mean atomic weight and the correction of the inconsistency aforementioned. In addition, we show that the cut-off periods obtained analytically are consistent with the corresponding periods measured in observations of a particular active region.
