最近对H. cap . alpha.的敏感搜索球状星团中电离的星团内气体的辐射设定了与理论预测相冲突的上限。我们认为新星爆发加热了气体，产生的风解决了这种差异。讨论了球状星团中新星的发生、新星壳的动能转化为星团内气体的热能，以及由此产生的风的特征。由新星驱动的模型计算出的辐射与迄今为止的任何观测结果都不冲突。在这些模型的基础上，对未来探测星系团内气体最有希望的方法提出了一些建议。此外，还考虑了新星驱动风与球状星团x射线源之间的可能关系。
Recent sensitive searches for H..cap alpha.. emission from ionized intracluster gas in globular clusters have set upper limits that conflict with theoretical predictions. We suggest that nova outbursts heat the gas, producing winds that resolve this discrepancy. The incidence of novae in globular clusters, the conversion of kinetic energy of the nova shell to thermal energy of the intracluster gas, and the characteristics of the resultant winds are discussed. Calculated emission from the nova-driven models does not conflict with any observations to date. Some suggestions are made concerning the most promising approaches for future detection of intracluster gas on the basis of these models. The possible relationship of nova-driven winds of globular cluster X-ray sources is also considered.
