By observing the energy band of hard x - ray, people not only can expand a series of studies to celestial bodies or phenomena of nova and supernova ' s breaking out, nucleus ' s compose, but also many interactional process of thermal braking radiation, synchronal radiation
硬x射能區的天文觀測一方面可以研究一系列的天體目標或超新星和新星的爆發、核合成等現象,另一方面也可以研究一系列的相互作用的過程:熱韌致輻射、同步輻射等。Topics include : planets, planet formation ; stars, the sun, " normal " stars, star formation ; stellar evolution, supernovae, compact objects ( white dwarfs, neutron stars, and black holes ), plusars, binary x - ray sources ; star clusters, globular and open clusters ; interstellar medium, gas, dust, magnetic fields, cosmic rays ; distance ladder ; galaxies, normal and active galaxies, jets ; gravitational lensing ; large scaling structure ; newtonian cosmology, dynamical expansion and thermal history of the universe ; cosmic microwave background radiation ; big - bang nucleosynthesis
課程的主題包含了:行星、行星形成;恆星、太陽、正常的恆星、恆星形成;恆星演化、超新星、緻密天體(白矮星、中子星及黑洞) 、波霎、雙x -射線源;星團、球狀及疏散星團;星際介質、氣體、塵埃、磁場、宇宙射線;距離階梯;星系、正常及活躍星系、噴流;重力透鏡;大尺度結構;牛頓宇宙學、宇宙的動力膨脹及溫度發展歷史;宇宙背景微波輻射;大霹靂核合成。If the mass of the core after a supernova explosion is more than 1. 4 but less than about 3 solar masses, then electron degenerate pressure is not strong enough to support the star. the star will contract to a size even smaller than the white dwarf. the electrons are squeezed into the nuclei and are combined with the protons to form neutrons
假若在超新星爆發后,剩餘核心質量介乎太陽質量的1 . 4至3倍,那麼核心中的電子簡並壓力便再不足以抵抗強大的引力,恆星會進一步收縮,直至電子亦被擠壓至原子核內,和質子結合成為中子。This letter aiming at this respect, hints for neutron capture element are derived : 1. based on the adopted galactic evolution scenario, together with the three - zone multi - phase model, observational features of the solar vicinty region can be well reproduced. among those are particuly g - dwarf problem. the g - dwarf problem in halo and thin - disk can be solved
本文正是從這方面著手,對中子俘獲元素進行了研究,得到如( 1 ) r過程元素核合成產量隨著超新星前身星的質量的增加而單調增加, r -過程核合成場所是sn ,質量范圍是18m _ m 50m _ ,這與mathews 、 tsujimoto和travaglio等人的結果完全不同。分享友人
