Abstract

Based on Gaia DR3 data, a new revision of the stellar content is performed within the \(20^{\prime}\)-radius field centered on the young open cluster vdB 130, which is a part of the Cyg OB1 stellar association. A total of 97 stars and 39 protostars of luminosity classes I/II/III are identified that have proper-motion based cluster membership probabilities \(P>0.98\). The total number of possible cluster members with membership probabilities \(P>0.50\) is equal to about 300, and the cluster age estimated by fitting theoretical isochrones does not exceed 10 Myr. The trigonometric-parallax based cluster distance is \(D\approx 1670\pm 60\) pc, and the cluster color excess, \(E(BP-RP)\approx 0\overset{\textrm{m}}{.}85\pm 0\overset{\textrm{m}}{.}02\) with evidence for strong differential extinction.

基于Gaia DR3数据对星协Cyg OB1区域年轻疏散星团vdB 130恒星成分和物理性质的新修订

基于盖亚DR3的数据，在以年轻疏散星团vdB 130为中心的\(20^{\prime}\) -半径范围内对恒星内容进行了新的修订，vdB 130是Cyg ob1恒星协会的一部分。总共有97颗恒星和39颗亮度等级为I/II/III的原恒星被确定为具有基于运动的适当的星团隶属概率\(P>0.98\)。具有隶属概率\(P>0.50\)的可能星团成员总数大约等于300个，通过拟合理论等时线估计的星团年龄不超过10 Myr。基于三角视差的聚类距离为\(D\approx 1670\pm 60\) pc，聚类颜色过剩，\(E(BP-RP)\approx 0\overset{\textrm{m}}{.}85\pm 0\overset{\textrm{m}}{.}02\)具有强差消光的证据。
