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.
