Abstract We present new trigonometric parallaxes and proper motions of young stellar objects in the Taurus molecular cloud complex from observations collected with Very Long Baseline Array as part Gould’s Belt Distances Survey. detected 26 derived for 18 stars an accuracy 0.3% to a few percent. modeled orbits six binaries determined dynamical masses individual components four these systems (V1023 Tau, T Tau S, V807 V1000 Tau). Our results are consistent first delivered by Gaia satellite reveal existence significant depth effects. find that central portion dark Lynds 1495 is located at d =129.5 ± 0.3 pc, while B216 clump filamentary structure connected it = 158.1 1.2 pc. The closest remotest our sample 126.6 1.7 pc 162.7 0.8 yielding distance difference about 36 also provide estimate HL was recently imaged. Finally, we compute spatial velocity published radial investigate kinematic properties various clouds gas structures this region.
