临边增亮及其与毫米波空腔的关系

The Limb Brightening and its Relationship with the Millimeter-wave Cavity

Victor De la Luz, Miguel Chavez, Emanuele Bertone

摘要:

通过对毫米波、亚毫米波和红外波段(从10 GHz到10 THz)的局域发射的详细理论分析,我们发现,与温度最低值相关联的是,存在一个光学薄腔,腔体周围有两个高的局域发射率区域。我们称这种结构为色球太阳毫米波腔(CSMC)。为了在太阳边缘的射电观测中寻找这个空腔的踪迹,我们开发了一种鲁棒的方法,将不同高度的辐射与观测到的亮度温度联系起来。我们预见,这种方法将使我们能够确定CSMC和太阳临边增亮之间的关系。

英文摘要:

Through a detailed theoretical analysis of the local emission at millimeter,sub-millimeter and infrared wavelength regimes (from \~ 10 GHz up to \~ 10 THz), we found that, associated with the temperature minimum, there is an optically thin cavity surrounded by two regions of high local emissivity. We call this structure the Chromospheric Solar Millimeter Cavity (CSMC). In order to search for traces of this cavity in the available radio observations on the solar limb, we have developed a robust method to associate the radiation at different heights with the observed brightness temperatures. We foresee that this approach will allow us to determine the relationship between the CSMC and the solar limb brightening.
