The most interesting results of the study of the Galaxy by OB stars

A review of the main results of studying the structure and kinematics of the Galaxy obtained by various research teams using OB stars is given. The main attention is paid to the results of the authors of this work. The following questions are considered: a) the nature of the spatial distribution of OB stars in the Galaxy; b) the use of OB stars to refine the parameters of the spiral pattern of the Galaxy; c) refinement of the Galactic rotation parameters and perturbation velocities caused by the influence of the Galactic spiral density wave using OB stars; d) spatial and kinematic relationship of OB stars with galactic warp; e) analysis of the motion of some runaway OB stars.
