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.
Notes
Renormalized unit-weight errors.
