On the RR Lyrae stars in globulars: IV. Centauri Optical UBVRI Photometry
V. F. Braga, P. B. Stetson, G. Bono +31
New accurate and homogeneous optical UBVRI photometry has been obtained for variable stars in the Galactic globular Cen (NGC 5139). We secured 8202 CCD images covering a time i…
A photometric and spectroscopic survey of solar twin stars within 50 parsecs of the Sun: I. Atmospheric parameters and color similarity to the Sun
G. F. Porto de Mello, R. da Silva, L. da Silva +1
Solar twins and analogs are fundamental in the characterization of the Sun's place in the context of stellar measurements, as they are in understanding how typical the solar proper…
Accurate and homogeneous abundance patterns in solar-type stars of the solar neighbourhood: a chemo-chronological analysis
R. da Silva, G. F. Porto de Mello, A. C. Milone +3
We report the abundances of C, Na, Mg, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Y, Zr, Ba, Ce, Nd, and Sm in 25 solar-type stars in the solar neighbourhood, and their cor…
Photospheric parameters and C abundances in solar-like stars with and without planets
Ronaldo Da Silva, André Milone
We have been analyzing a large sample of solar-like stars with and without planets in order to homogeneously measure their photospheric parameters and Carbon abundances. Our sample…
