Investigating the vertical distribution of the disk as a function of radial action

Aims. As heating processes can broaden the distributions of radial actions and vertical Galactic disks, we investigate distribution disks as a function action based on Apache Point Observatory Evolution Experiment (APOGEE) Gaia data in order to deepen our understanding formation history disks. Methods. The thin thick defined chemical plane were fitted with simple exponential free parameter scale height different ranges. Therefore, able analyze for disk populations. Results. We find that both be approximately described by pseudo-isothermal distributions, which give statistical measurement temperature indicated mean star sample. Estimations heights ranges these seem show fixed relationships between J R h . describe two-parameter = √( / )+ b , where are parameters. When testing three-parameter α this describes well, but note should used care disk. comparing best-fit inner outer nearly same shows flattened relationship, while presents gradually increasing relationship. This work highlights an alternative way unveil investigating relationship action, encode
