On the nature of five open cluster candidates projected close to the Galactic centre

We present CCD BV I observations obtained for 1759 stars in 4′×4′ regions around the unstudied southern stellar aggregates Ruprecht 103, 124, 129, 146 and 166, which are described as open clusters in several catalogues. Our analysis shows that none of these stellar groups are genuine open clusters s...
