Today is paper day! Recently, I discovered two outbursts of the unusual recurrent nova M31N 2017-01e, one new (M31N 2024-08c), one old (M31N 2014-06c). After discussions with Prof. Allen Shafter from San Diego State University, an RNAAS paper was published today. 🔭

【承認】小惑星「アオ（Ao）」命名、漫画『恋する小惑星』にちなんだアプリによる発見 news.livedoor.com/article/deta... 小惑星は『恋する小惑星』の略称にちなんだ未発見小惑星検出アプリ『COIAS』を通じて発見。「アオ（Ao）」という名前は同漫画の2人の主人公が交わした“約束” に由来しているという。
太陽系に無数に存在する「小惑星」は、一定の条件を満たすことで名前を付けることができます。命名に関するルールは比較的緩いため、フィクション作品に登場する架空の人物に由来する名称も多数あります。国際天文学
According to the prediction, the recurrent nova T Corona Borealis (T CrB) will outburst in the near future, and global monitoring is very necessary. We sincerely invite amateur astronomers around the world to join our initiative on monitoring T CrB, please read the initiative below.🔭 🧪
Our amateur team has discovered an interesting eclipsing variable star near SH 2-241 nebula from ZTF archive data. It has a period about 830 days, more than 40% in occultation, with a bright peak at the centre of the occultation. 🔭🧪 Image Credit: DSS、PanSTARRS DR1

With T Coronae Borealis expected to have an outburst any day now, recurrent novae are in the news. Recently, researchers reported their investigation of a recurrent nova that brightens every year. aasnova.org/2024/05/17/s... 🔭🧪
With T Coronae Borealis soon rising to naked-eye visibility, recurrent novae are in the news. Recurrent nova M31N 2008-12a is the subject of today's article.
hep-ex paper of the day: for stars within 500pc of us, SuperK+KamLAND are sensitive to supernova neutrinos---but not just from the core collapse! They'll also see the final hours (up to a day!) of runaway nuclear heating! AND the signal is strongly mass-hierarchy sensitive via the MSW effect! 🧪⚛️
Preceding a core-collapse supernova, various processes produce an increasing amount of neutrinos of all flavors characterized by mounting energies from the interior of massive stars. Among them,...
In an urban area with serious light pollution, the Seestar S50 was used to monitor the upcoming outburst of the recurrent nova T CrB. Because Seestar S50 doesn't have this object in its database, I chose GOTO to the nearby galaxy IC 4587, which places T CrB almost perfectly at the center. 🔭
