NGC 6738: Not a real open cluster
@article{Boeche2003NGC6N, title={NGC 6738: Not a real open cluster}, author={Corrado Boeche and Roberto Barbon and Arne Anthon Henden and U. Munari and P. Agnolin}, journal={Astronomy and Astrophysics}, year={2003}, volume={406}, pages={893-898} }
A photometric, astrometric and spectroscopic investigation of the poorly studied open cluster NGC 6738 has been performed in order to ascertain its real nature. NGC 6738 is definitely not a physical stellar ensemble: photometry does not show a defined mean sequence, proper motions and radial velocities are randomly distributed, spectro-photometric parallaxes range between 10 and 1600 pc, and the apparent luminosity function is identical to that of the surrounding field. NGC 6738 therefore…
