Photometry and astrometry of M36 members
Listed in IVOA Registry (Virtual Observatory)
We present comprehensive characterization of the Galactic open cluster M36.
Description
Some 200 member candidates, with an estimated contamination rate of ~8%, have been identified on the basis of proper motion and parallax measured by the Gaia DR2. The cluster has a proper motion grouping around ({mu}_{alpha}_cos{delta}=-0.15+/-0.01mas/yr, and {mu}_{delta}_=-3.35+/-0.02mas/yr), distinctly separated from the field population.
Most member candidates have parallax values 0.7-0.9mas, with a median value of 0.82+/-0.07mas (distance ~1.20+/-0.13kpc). The angular diameter of 27'+/-0.4' determined from the radial density profile then corresponds to a linear extent of 9.42+/-0.14pc. With an estimated age of ~15Myr, M36 is free of nebulosity.

To the southwest of the cluster, we discover a highly obscured (A_V_ up to ~23mag), compact (~1.9'x1.2') dense cloud, within which three young stellar objects in their infancy (ages <~0.2Myr) are identified. The molecular gas, 3.6pc in extent, contains a total mass of (2-3)x10^2^M_{sun}_, and has a uniform velocity continuity across the cloud, with a velocity range of -20 to -22km/s, consistent with the radial velocities of known star members.
In addition, the cloud has a derived kinematic distance marginally in agreement with that of the star cluster. If physical association between M36 and the young stellar population can be unambiguously established, this manifests a convincing example of prolonged star formation activity spanning up to tens of Myr in molecular clouds.
