关于G9 .62+ 0.20 E周期甲醇脉泽的注记

A note on the periodic methanol masers in G9.62+0.20E

DJ van der Walt, JM Maswanganye, S Etoka, S Goedhart, SP van den Heever

摘要:

在过去,人们提出了一些机制来理解与一些高质量恒星形成区相关的周期性II类甲醇脉泽。最近的两个建议,即。Parfenov &Sobolev(2014)和Sanna等人(2015)提出的理论,以解释具有类似于G9.62+0.20E中甲醇脉泽的光变曲线的源中的周期性脉泽。我们评估了这些作者提出的建议和模型在多大程度上可以解释G9.62+0.20E甲醇脉泽的光变曲线。这两种机制都不能再现G9.62+0.20E甲醇脉泽的光变曲线。

英文摘要:

A number of mechanisms to understand the periodic class II methanol masers associated with some high-mass star forming regions have been proposed in the past. Two recent proposals, ie. by Parfenov &Sobolev (2014) and Sanna et al. (2015) have been presented in order to explain the periodic masers in sources with light curves similar to the methanol masers in G9.62+0.20E. We evaluate to what extent the proposals and models presented by these authors can explain the light curve of the methanol masers in G9.62+0.20E. It is argued that neither of the proposed mechanisms can reproduce the light curves of the methanol masers in G9.62+0.20E.
