Galactic kinematics

WebNov 9, 2024 · The kinematic parameters as a function of Galactic coordinates were derived for the first time. Also, for the first time, the parameters ∂ VR /∂θ and ∂ Vθ /∂θ were derived. methods: data analysis – proper motions – stars: kinematics and dynamics – Galaxy: kinematics and dynamics – solar neighbourhood Issue Section: Article 1 INTRODUCTION Webkinematics is analyzed in terms of galactic populations. LPVs are found to belong to galactic populations ranging from the thin disk to the extended disk. An age range and a lower limit of the initial mass is given for stars of each population. A di erence of 1.3 mag in K for the upper limit of the Asymptotic Giant Branch is found
