Abstract:
We have obtained CCD BVIKC photometry down to V∼21.5 for the open
cluster Lynga 11 and its surrounding field. This previously unstudied
object appears to be rich and highly absorbed. A cluster angular
radius of 4.5±0.5, equivalent to (3.0±0.3)pc, is estimated from
star counts in 100-pixel a side boxes distributed throughout the whole
observed field. Our analysis suggests that Lynga 11 is moderately
young and probably of solar metallicity.
Description:
CCD images of the cluster field were obtained with the Johnson B and V
and Kron-Cousins I filters during the same night in which they were
obtained for NGC 6318, whose analysis was published by Piatti et al.
(2005, Cat. J/PASP/117/22, hereafter Paper I).
