# 2110.10181 - https://arxiv.org/abs/2110.10181 - **Spatially Resolved X-ray Study of Supernova Remnant G306.3−0.9 with Unusually High Calcium Abundance** - local experts: **翁建斌** # 2110.12220 - https://arxiv.org/abs/2110.12220 - **A global view of shocked plasma in the supernova remnant Puppis A provided by SRG/eROSITA** - An interesting method of narrow-band X-ray mapping. - by **张孟飞** # 2110.10786 - https://arxiv.org/abs/2110.10786 - **Possible X-ray Quasi-Periodic Eruptions in a Tidal Disruption Event Candidate** This paper reports the fifth QPE candidate XMMSL1 J024916.6-041244, which has previously been identified as a TDE candidate, from a a blind algorithm-assisted search of the XMM-Newton Source Catalog. The QPE-like soft X-ray flare emerges in 2006 observation with one and half time, while disappears in the following XMM-Newton observation in August 2021. Unlike other QPE sources, there are hints of corresponding dips in the UV light curves. - by **鲍通** # 2110.14058 - https://arxiv.org/abs/2110.14058 - **The Remarkable Spin-down and Ultra-fast Outflows of the Highly-Pulsed Supersoft Source of Nova Hercules 2021** - Nova Hercules 2021 (V1674 Her), which erupted in June 2021, is suggested to host a magnetic white dwarf with optical pre-outburst detection. In this paper, the authors report Swift and Chandra observations on V1674 Her during the X-ray outburst. They find a strong modulation of supersoft X-rays at a different period from reported optical periods. The difference between X-ray and optical pulsation periods may come from non-rigid photospheric rotation. P Cygni-like line profiles indicate outflows expanding at remarkable speeds up to 11000 km/s. - by **苏钊**
