NGC 2243 is a Open Cluster in the Canis Major constellation. NGC 2243 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its visual magnitude of 9.4, NGC 2243 is visible with the help of a binocular with a 60-70mm aperture or a small telescope.

2004年2月1日 · Amateur astronomers using 12-inch or larger telescopes will be able to see more than 100 stars in NGC 2243, an old open cluster in Canis Major. For open clusters, wandering …

2021年3月3日 · High-dispersion spectra in the Li λ 6708 region have been obtained and analyzed in the old, metal-deficient cluster NGC 2243. From Hydra spectra for 29 astrometric and radial velocity members, we derive rotational velocities, as well as [Fe/H], [Ca/H], [Si/H], and [Ni/H] based on 17, 1, 1, and 3 lines, respectively.

Our aim was to determine the initial Li content of two clusters of similar metallicity but very different ages, the old open cluster NGC 2243 and the metal-rich globular cluster NGC 104. Methods. We compared the lithium abundances derived for a large sample of stars (from the turn-off to the red giant branch) in each cluster.

NGC 2243 is an old and metal-poor OC located towards the anti-center at RG = 10.76 kpc and of the Milky Way (lII = 239 .478, bII = −18 .014). The first CCD photometry of NGC 2243 was obtained by Bonifazi et al. (1990) who found an age of 4 ± 1 Gyr, a metallicity of [Fe/H]=

2021年2月9日 · High-dispersion spectra in the Li 6708 Angstrom region have been obtained and analyzed in the old, metal-deficient cluster, NGC 2243. From Hydra spectra for 29 astrometric and radial-velocity members, we derive rotational velocities, as well as [Fe/H], [Ca/H], [Si/H], and [Ni/H] based on 17, 1, 1, and 3 lines, respectively.
