On the Use of Field RR Lyrae as Galactic Probes. V. Optical and radial velocity curve templates
V. F. Braga, J. Crestani, M. Fabrizio +29
We collected the largest spectroscopic catalog of RR Lyrae (RRLs) including 20,000 high-, medium- and low-resolution spectra for 10,000 RRLs. We provide the analy…
On the Use of Field RR Lyrae as Galactic Probes. II. A new S calibration to estimate their metallicity
J. Crestani, M. Fabrizio, V. F. Braga +33
We performed the largest and most homogeneous spectroscopic survey of field RR Lyraes (RRLs). We secured 6,300 high resolution (HR, R35,000) spectra for 143 RRLs (11…
Massive open star clusters using the VVV survey V. Young clusters with an OB stellar population
S. Ramírez Alegría, J. Borissova, A. -N. Chené +6
The ESO public survey VISTA Variables in the Vía Láctea (VVV) has contributed with deep multi-epoch photometry of the Galactic bulge and the adjacent part of the disk over 526 squa…
Physical parameters of 15 intermediate-age LMC clusters from modelling of HST colour-magnitude diagrams
L. O. Kerber, B. X. Santiago, E. Brocato
We analyzed HST/WFPC2 colour-magnitude diagrams (CMDs) of 15 populous Large Magellanic Cloud (LMC) stellar clusters with ages between ~ 0.3 Gyr and ~ 3 Gyr. These (V, B-V) CMDs are…
Mass segregation in rich LMC clusters from modelling of deep HST colour-magnitude diagrams
L. O. Kerber, B. X. Santiago
We used the deep colour-magnitude diagrams (CMDs) of five rich LMC clusters (NGC1805, 1818, 1831, 1868, and Hodge14) observed with HST/WFPC2 to derive their present day mass functi…
The Relationship Between the Sersic Law Profiles Measured Along the Major and Minor Axes of Elliptical Galaxies
Fabricio Ferrari, Horacio Dottori, Nicola Caon +2
In this paper we discuss the reason why the parameters of the Sersic model best-fitting the major axis light profile of elliptical galaxies can differ significantly from those deri…
