Radio flux variability in UCHII regions

Theoretical models of early accretion during the formation process of massive stars have predicted that HII regions exhibit radio variability on timescales of decades. However,...针对大质量恒星（massive stars）形成过程中早期吸积环节的理论模型曾预测，电离氢区（HII regions）会呈现出十年量级时间尺度的射电变异性（radio variability）。然而，
