Models for the 3-D axisymmetric gravitational potential of the Milky Way Galaxy - A detailed modelling of the Galactic disk
D. A. Barros, J. R. D. Lépine, W. S. Dias
Aims. Galaxy mass models based on simple and analytical functions for the density and potential pairs have been widely proposed in the literature. Disk models constrained by kinema…
Fitting isochrones to open cluster photometric data III. Estimating metallicities from UBV photometry
A. F. Oliveira, H. Monteiro, W. S. Dias +1
The metallicity is a critical parameter that affects the correct determination fundamental characteristics stellar cluster and has important implications in Galactic and Stellar ev…
Overlapping abundance gradients and azimuthal gradients related to the spiral structure of the Galaxy
J. R. D. Lepine, P. Cruz, S. Scarano +6
The connection between some features of the metallicity gradient in the Galactic disk, best revealed by Open Clusters and Cepheids, and the spiral structure, is explored. The step-…
Fitting Isochrones to Open Cluster photometric data: A new global optimization tool
H. Monteiro, W. S. Dias, T. C. Caetano
We present a new technique to fit color-magnitude diagrams of open clusters based on the Cross-Entropy global optimization algorithm. The method uses theoretical isochrones availab…
New catalogue of optically visible open clusters and candidates
W. S. Dias, B. S. Alessi, A. Moitinho +1
We have compiled a new catalogue of open clusters in the Galaxy which updates the previous catalogues of Lynga (1987) and of Mermilliod (1995) (included in the WEBDA database). New…
