标题： Radio Supernova 1987A at 843 MHz

摘要： 我们报告了从1994年9月至2000年5月使用莫朗戈天文台综合望远镜观测到的正在演化的射电源SN1987A在843 MHz处的流量密度测量结果。射电光变曲线表明流量密度的增长率在第2800至3000天（即1995年上半年）显著跃升，并且自那时起，射电演化可以用简单的线性增长（(62.7 ± 0.5）微焦耳/天）很好地拟合。我们详细讨论了射电光变曲线与该系统光学波段亮度增加之间的关系。 显示英文摘要

摘要： We report the flux densities of the evolving radio source SN1987A at 843 MHz measured from observations made with the Molonglo Observatory Synthesis Telescope between 1994 September and 2000 May. The radio light curve shows that the rate of increase of the flux density jumped markedly around days 2800-3000 (i.e. in the first half of 1995), and that since then the radio evolution has been remarkably well fitted by a simple linear increase of (62.7 +- 0.5) microJansky/day. We discuss in detail the relationship between the radio light curve and the recent brightening of the system at optical wavelengths.
