【摘要】 本文通过对1700多颗在银道面附近2.2μm红外源的计数统计,求出了红外源的真实密度分布D(R)和红外星的光度函数(M);由此,求出了年青红外源的总数为1.652×10~9颗及它的产星率为0.83个/a.更多还原

【Abstract】 The space distribution of 2.2μm infrared sources within the Galactic disk is researched exhaustively. Through counting statistics for over 1700 infrared sources nearby the Galactic plane, the expression of density D(R) and lumi- nosity function(M) of infrared sources are obtained. From the density D (R), it can be estimated that the sum total and birthrate of these young infrared sources are 1.652×10~9 and 0.83/a respectively.更多还原
