NGC 6866 is a young [5] open cluster of stars in the northern constellation Cygnus. It was discovered by German astronomer Caroline Herschel on 23 July 1783. [3] This cluster is located at an estimated distance of 4.35 ± 0.53 thousand light-years from the Sun, [2] and is circling the Galactic Center with a slight orbital eccentricity of 0.12. [7]

NGC 6866 is a Open Cluster in the Cygnus constellation. NGC 6866 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its visual magnitude of 7.6, NGC 6866 is visible with the help of a binocular with a 40-50mm aperture or a small telescope.

2023年8月24日 · We aim to measure asteroseismic properties of oscillating giant members of the open cluster NGC 6866 and utilise these for a cluster age estimate. Model comparisons allow constraints on the stellar physics, and here we investigate the efficiency of convective-core overshoot and effects of rotation during the main-sequence, which has a ...

We aim to identify and measure the asteroseismic properties of oscillating giant members of the open cluster NGC 6866 and utilise them for a cluster age estimate. Model comparisons also allow constraints to be placed on the stellar physics.

2023年9月4日 · Using NASA's Kepler and ESA's Gaia spacecraft, an international team of astronomers has conducted an astroseismic investigation of six giant stars in the open cluster NGC 6866. The study,...

The age of NGC 6866 is estimated to be 0.43 ± 0.05 Gyr, which is significantly younger and more precise than most previous estimates. Conclusions: We derive a precise cluster age while constraining convective-core overshooting and the effects of rotation in the stellar models.

2014年5月2日 · The four open clusters located in NASA's Kepler spacecraft field of view (NGC 6866, NGC 6811, NGC 6819, and NGC 6791), which range in age from less than 1 Gyr to more than 8 Gyr, are ideal targets for a variety of astrophysical investigations.

2015年7月21日 · We present CCD UBVRI photometry of the field of the open cluster NGC 6866. Structural parameters of the cluster are determined utilizing the stellar density profile of the stars in the field.
