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]

NGC 5822 is a Open Cluster in the Lupus constellation. NGC 5822 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its visual magnitude of 6.5, NGC 5822 is visible with the help of a small binocular.

2011年8月2日 · NGC 5822 is a richly populated, moderately nearby, intermediate-age open cluster covering an area larger than the full moon on the sky.

In this paper, we present a spectroscopic survey of MSTO stars in the nearby (∼760pc) intermediate-age (0.9Gyr) open cluster NGC 5822. We find the presence of an eMSTO in this cluster and verify that it is not an artifact caused by differential extinction.

2019年4月6日 · We present a spectroscopic survey of MSTO stars in a nearby, intermediate-age (\unit [0.9] {Gyr}), low mass (∼ 1.7 ×103M⊙) Galactic open cluster, NGC 5822. We derive a clean sample of member stars based on \textit {Gaia} proper motions and parallaxes and confirm the existence of an eMSTO.

NGC 5822是狼疮南部星座中的一个开放式恒星。 它是由英国天文学家约翰·赫歇尔（John Herschel）于1836年7月3日发现的，并靠近另一个集群NGC 5823 ，这表明可能存在身体关联。

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.

2012年6月28日 · NGC 5822 is an in the constellation . It has an apparent visual magnitude of 10.3 and its angular diameter is 39 arc-minutes. NGC 5822 lies at an estimated distance of 2990 light years. The Equinox 2000 coordinates are 15h 04.4m, -54° 24´ which makes NGC 5822 a Southern Hemisphere object that is best seen during the summer.

NGC 5822 40 minutes exposure, Fuji Superia 400 film. 5" f/5 refractor, prime focus. NGC 5822 is a large, scattered open cluster in Lupus. A very low magnification is required to view the entire cluster. There is no concentration of stars towards the centre.
