Aims: This paper has two main objectives: (1) To determine the intrinsic properties of 16 faint and mostly unstudied open clusters in the poorly known sector of the Galaxy at 270$^\circ-$300$^\circ$, to probe the Milky Way structure in future investi

Early-type stars in the open cluster NGC 4852

Autor: E. E. Giorgi, J. A. Ahumada, Ruben Angel Vazquez, G. R. Solivella

Publikováno v: Monthly Notices of the Royal Astronomical Society. 415:1355-1365

The southern open cluster NGC 4852 was re-observed in the UBVRI passbands to refine its intrinsic fundamental parameters. An extended spectral coverage was also undertaken aimed at obtaining a clear picture of the kind of stars inhabiting the cluster

Revealing the parameters of the open cluster Ruprecht 58

Autor: J. Núñez, E. E. Giorgi, Ruben Angel Vazquez, G. R. Solivella, R. B. Orellana

Publikováno v: New Astronomy. 12:461-470

We present results of a study that combines UBVI photometry, MK spectral classification and proper motions in the area of the, up to now unknown, open cluster Ruprecht 58 at the Puppis region. Star counts from the 2MASS data catalog together with the

The nearby Galaxy structure toward the Vela Gum nebula

Autor: Ruben Angel Vazquez, G. R. Solivella, E. E. Giorgi, G. I. Perren

We report on $UBVI$ photometry and spectroscopy for MK classification purposes carried out in the fields of five open clusters projected against the Vela Gum in the Third Galactic Quadrant of the Galaxy. They are Ruprecht 20, Ruprecht 47, Ruprecht 60

In the third Galactic quadrant (180° ≤ l ≤ 270°) of the Milky Way, the Galactic thin disk exhibits a significant Warp-shown both by gas and young stars-bending down a few kiloparsecs below the formal Galactic plane (b = 0°). This warp shows it

CCD UBVI imaging photometry was carried out in the fields of the open clusters Pismis 8 and Pismis 13, located in the Vela-Puppis region in our Galaxy. MK spectral types have also been determined for a number of stars located in the fields of these t

Galactic open clusters do not survive long in the high density regions of the inner Galactic disc. Inside the solar ring only 11 open clusters are known with ages older than one Gyr. We show here, basing on deep, high-quality photometry, that NGC 433

With the discovery of the Sagittarius dwarf spheroidal (Ibata et al. 1994), a galaxy caught in the process of merging with the Milky Way, the hunt for other such accretion events has become a very active field of astrophysical research. The identific

We present CCD broad band photometric observations in the fields of the Third Galactic Quadrant open clusters NGC 2580 and NGC 2588 ($V(I)_C$ and $UBV(RI)_C$ respectively). From the analysis of our data we found that NGC 2580 is located at a distance

CCD UBVI imaging photometry was carried out in the field of the open cluster NGC 2571. From the analysis of our data we state the cluster is at a distance of 1380 ± 130 pc and its age is 504±10 ×106 yr. The cluster mass function has a slope larger
