论文摘要
我们介绍了对金牛座恒星形成区域中年轻磁盘恒星的可变性特性的全面研究，与我们先前在Rho OPH和上SCO进行的研究并行。将99个确认的金牛座关联的样本放置在通量不对称（M）和准周期性（Q）的诊断Q-M平面中，该平面指导我们的可变性类别分配。我们发现金牛座中的通量对称变量的比例相似，但相对于上sco，更多的助力器和北枝较少。这些区域的不同之处在于，金牛座的周期性和准周期源相对于更具进化的上SCO星/磁盘系统而言，周期性和准周期源的幅度更大。相对于可用的磁盘倾斜度测量值，评估了在内部磁盘和恒星表面上出现的光波长的光度变异性模式之间的关系。
We present a comprehensive study of the variability properties of young disk-bearing stars in the Taurus star-forming region, paralleling our previous investigation in rho Oph and Upper Sco. A sample of 99 confirmed Taurus association members is placed in the diagnostic Q-M plane of flux asymmetry (M) and quasi-periodicity (Q), which guides our assignment of variability classes. We find a similar proportion of flux-symmetric variables in Taurus, but more bursters and fewer dippers relative to Upper Sco. The regions also differ in that the amplitudes for periodic and quasi-periodic sources are larger in Taurus relative to the more evolved Upper Sco star/disk systems. The relationship between photometric variability patterns at optical wavelengths, which arise in the inner disk and at the stellar surface, are assessed relative to available disk inclination measurements.
