Young stellar objects Gaia EDR3 properties
Listed in IVOA Registry (Virtual Observatory)
Identifying the young optically visible population in a star-forming region is essential for fully understanding the star formation event.
Description
In this paper, we identify 211 candidate members of the Perseus molecular cloud based on Gaia astrometry. We use LAMOST spectra to confirm that 51 of these candidates are new members, bringing the total census of known members to 856.
The newly confirmed members are less extincted than previously known members. Two new stellar aggregates are identified in our updated census. With the updated member list, we obtain a statistically significant distance gradient of 4.84pc/deg from west to east.

Distances and extinction corrected color-magnitude diagrams indicate that NGC1333 is significantly younger than IC348 and the remaining cloud regions. The disk fraction in NGC1333 is higher than elsewhere, consistent with its youngest age. The star formation scenario in the Perseus molecular cloud is investigated and the bulk motion of the distributed population is consistent with the cloud being swept away by the Per-Tau Shell.
