Interstellar extinction

DENIS observations in the J(1.25{mu}m) and K_S_(2.15{mu}m) bands together with isochrones calculated for the RGB and AGB phase are used to draw an extinction map of the inner...本研究采用近红外深空巡天（DENIS）在J（1.25μm）与K_S（2.15μm）波段的观测数据，结合针对红巨星分支（RGB，Red Giant Branch）与渐近巨星分支（AGB，Asymptotic Giant Branch）阶段计算得到的恒星演化等时线，以绘制内部区域的消光图。
