Accretion in disks in Cep OB2

We present accretion rates for a large number of solar-type stars in the Cep OB2 region, based on U-band observations. Our study comprises 95 members of the ~4Myr old cluster Tr...本研究基于U波段（U-band）观测数据，为仙王座OB2（Cep OB2）天区内的大量类太阳恒星（solar-type stars）提供了吸积率（accretion rates）的测算结果。本研究涵盖了年龄约4Myr的Tr星团的95个成员天体。
