Abstract

It is known that so-called solar flares systematically occur in the area of sunspots. They are accompanied by radiation in almost all frequency ranges and sometimes by the emission of hot plasma. Observations on the RATAN-600 radio telescope have shown that the radio emission spectrum of plasma clouds heated to values of the order of 106 K erupted from the solar flare region turned out to be adiabatic. The high correlation of the inhomogeneities of the radio emission spectra of active formation over a group of sunspots indicates the stable presence of recombination radio lines in the radiation of active formation. However, the radio emission spectra of hot plasma clouds ejected from the region of solar flares occurring in this group of spots do not show any correlation.

太阳耀斑期间等离子体云无线电发射的绝热频谱和云无线电发射频谱的不均匀性
摘要 众所周知,所谓的太阳耀斑系统地发生在太阳黑子区域。太阳耀斑伴随着几乎所有频率范围的辐射,有时还伴随着热等离子体的发射。RATAN-600 射电望远镜的观测结果表明,从太阳耀斑区域喷发的等离子体云加热到 106 K 量级时的射电发射光谱是绝热的。一组太阳黑子上活跃形成的射电发射光谱的不均匀性高度相关,表明在活跃形成的辐射中稳定存在重组射电线。然而,从这组太阳黑子点发生的太阳耀斑区域喷射出的热等离子体云的射电发射光谱却没有显示出任何相关性。
