Abstract We present UV and/or optical observations and models of SN 2023ixf, a type II supernova (SN) located in Messier 101 at 6.9 Mpc. Early time ( flash ) spectroscopy obtained primarily Lick Observatory, reveals emission lines H i , He i/ii C iv N iii/iv/v with narrow core broad, symmetric wings arising from the photoionization dense, close-in circumstellar material (CSM) around progenitor star prior to shock breakout. These electron-scattering broadened line profiles persist for ∼8 days...
The relationship between swimming performance and shoulder muscle strength at different distances is unclear. To provide a theoretical basis for future targeted training as well better detection prevention of water polo related injuries. analyze the correlation speed joint strength. Eleven members Chinese men's team were included subjects, BIODEX isokinetic tester was used to test flexion, extension, rotation, abduction-adduction muscles on both sides shoulder. And stopwatch measure speed....
Fluorine is one of the most interesting elements in nuclear astrophysics, where ^{19}F(p,α)^{16}O reaction crucial importance for Galactic ^{19}F abundances and CNO cycle loss first generation Population III stars. As a day-one campaign at Jinping Underground Nuclear Astrophysics experimental facility, we report direct measurements essential ^{19}F(p,αγ)^{16}O channel. The γ-ray yields were measured over E_{c.m.}=72.4-344 keV, covering Gamow window; our energy 72.4 keV unprecedentedly low,...
The ^{13}C(α,n)^{16}O reaction is the main neutron source for slow-neutron-capture process in asymptotic giant branch stars and intermediate process. Direct measurements at astrophysical energies above-ground laboratories are hindered by extremely small cross sections vast cosmic-ray-induced background. We performed first consistent direct measurement range of E_{c.m.}=0.24 to 1.9 MeV using accelerators China Jinping Underground Laboratory Sichuan University. Our covers almost entire Gamow...
The ^{18}O(α,γ)^{22}Ne reaction is critical for AGB star nucleosynthesis due to its connection the abundances of several key isotopes, such as ^{21}Ne and ^{22}Ne. However, ambiguous resonance energy spin-parity dominant 470 keV leads substantial uncertainty in rate temperature interest. We have measured energies strengths low-energy resonances at Jinping Underground Nuclear Astrophysics experimental facility (JUNA) with improved precision. has been be E_{α}=474.0±1.1 keV, high precision...

$^{26}\mathrm{Al}$ with a half-life of $7.17\ifmmode\times\else\texttimes\fi{}{10}^{5}$ years is one the most significant nuclides in $\ensuremath{\gamma}$-ray astronomy and presolar grains meteorites. Its main production mechanism $\mathrm{H}$-burning MgAl cycle $^{25}\mathrm{Mg}(p,\ensuremath{\gamma})^{26}\mathrm{Al}$ reaction. In temperature region 0.05--0.3 GK astrophysical interest, reaction rate dominated by resonant capture several low-energy resonances. this work, we report results...

Abstract Proton capture reactions on Mg isotopes are significant in the Mg-Al cycle stellar H -burning. In particular, resonance strengths and branching ratios of low-energy resonances 25 Mg( ) 26 Al determine production Al, which is one most important long-lived radioactive nuclei nuclear astrophysics. this article, we report our first experiment using intense proton beam approximately 2 mA provided by JUNA accelerator ground laboratory a new technique that can minimize composition change...
