NGC 5822 is an open cluster of stars in the southern constellation of Lupus. [7] It was discovered by English Astronomer John Herschel on July 3, 1836, [2] and lies close to another cluster, NGC 5823, which suggests there may be a physical association. [8][9]

We present a spectroscopic survey of MSTO stars in a nearby, intermediate-age (0.9 Gyr), low-mass (∼1.7 × 10 3 M ⊙) Galactic open cluster, NGC 5822. We derive a clean sample of member stars based on Gaia proper motions and parallaxes and confirm the existence of an eMSTO.

2013年7月15日 · Stars NGC 5822-2 and NGC 5822-201 are two barium stars found in the open cluster NGC 5822. They have, respectively, a mean overabundance of the elements created by slow-neutron capture reactions, " s," with the notation [s /Fe] of 0.77 ± 0.12 and 0.83 ± 0.05, which is much higher than stars at similar metallicities.
