摘要

在最快速递归新星（RN）M31N 2008-12a 周围发现了典型的新星超级残留物（NSR）。对NSR生长的模拟显示，这些大型结构应该存在于所有新星周围，无论是经典新星还是周期新星。NSR由围绕着挖掘出的空洞的大型壳状结构组成。根据这些模拟的预测，我们在 IRAS 远红外档案图像中发现了一个与银河系 RN（RS Ophiuchi）重合的扩展空腔。我们认为这个空洞与欧斐RS有关，因此是另一个有待发现的NSR的证据。

Discovery of a nova super-remnant cavity surrounding RS Ophiuchi

The prototypical nova super-remnant (NSR) was uncovered around the most rapidly recurring nova (RN), M31N 2008-12a. Simulations of the growth of NSRs revealed that these large structures should exist around all novae, whether classical or recurrent. NSRs consist of large shell-like structures surrounding excavated cavities. Predictions, informed by these simulations, led to the discovery of an extended cavity coincident with the Galactic RN, RS Ophiuchi, in far-infrared archival IRAS images. We propose that this cavity is associated with RS Oph and is therefore evidence of another NSR to be uncovered.

期刊介绍： For papers that merit urgent publication, MNRAS Letters, the online section of Monthly Notices of the Royal Astronomical Society, publishes short, topical and significant research in all fields of astronomy. Letters should be self-contained and describe the results of an original study whose rapid publication might be expected to have a significant influence on the subsequent development of research in the associated subject area. The 5-page limit must be respected. Authors are required to state their reasons for seeking publication in the form of a Letter when submitting their manuscript.
