1.Introduction Galactic Chemical Evolution(GCE) studies are to investigate the spatial and temporal evolution of the chemical abundances in the interstellar medium(ISM) in galaxies.This process is closely related to two important parameters in galaxy evolution:the initial mass function (IMF) and the star formation rate(SFR).It is also related to the primordial abundances,the nucleosynthesis and gas flows,including the radial flows,outflow and feedback 相似文献

Binary population synthesis(BPS),an approach to evolving millions of stars(including binaries) simultaneously,plays a crucial role in our understanding of stellar physics,the structure and evolution of galaxies,and cosmology.We proposed and developed a BPS approach,and used it to investigate the formation of many peculiar stars such as hot subdwarf stars,progenitors of type la supernovae,barium stars, CH stars,planetary nebulae,double white dwarfs,blue stragglers,contact binaries,etc.We also established an ... 相似文献

In this article,we report a few advances in the studies based on the solar vector magnetic field observations which were carried out mainly with the Solar Magnetic Field Telescope at the Huairou Solar Observing Station in the 1990s.(1) We developed necessary methodology and concepts in vector magnetogram analysis(Wang et al.1996).For the first time,we proposed to use the photospheric free magnetic energy to quantify the major flare productivity of solar active regions(ARs),and it had been proved to be the best parameter in representing the major flare activity.(2) We revealed that there was always a dominant sense of magnetic shear in a given AR(Wang 1994),which was taken as the premise of the helicity calculation in ARs;we made the first quantitative estimation of magnetic helicity evolution in ARs(Wang 1996).(3) We identified the first group of evidence of magnetic reconnection in the lower solar atmosphere with vector magnetic field observations and proposed a two-step reconnection flare model to interpret the observed association of flux cancellation and flares(Wang and Shi 1993).Efforts to quantify the major flare productivity of super active regions with vector magnetic field observations have been also taken. 相似文献

Coronal mass ejections（CMEs） are a major form of solar activities.A CME takes away 1015-16 g of plasma from solar low corona,to disturb the near-Earth space if the CME direction is favorable.Here we summarize our understandings and reasoning that lead us to conclude that CMEs are the unavoidable products of magnetic helicity accumulation in the corona.Our study puts the formation of magnetic flux ropes and CME eruptions as natural and unavoidable results of coronal evolution. 相似文献
