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…
Search for associations containing young stars. III- Ages and Li abundances
L. da Silva, C. A. O. Torres, R. de la Reza +3
Our study is a follow-up of the SACY project, an extended survey in the Southern Hemisphere targeted to search for young nearby associations. Nine associations have either been new…
SACY - a Search for Associations Containing Young stars
Carlos A. O. Torres, Germano R. Quast, Ramiro de la Reza +3
The scientific goal of the SACY (Search for Associations Containing Young-stars) was to identify possible associations of stars younger than the Pleiades Association among optical…
SACY - Present Status
C. A. O. Torres, G. R. Quast, R. de la Reza +2
The scientific goal of the SACY (Search for Associations Containing Young-stars) project is to identify eventual associations of stars younger than the Local Association, spread am…
Rapidly-rotating lithium-rich K giants: The new case of the giant PDS365
Natalia A. Drake, Ramiro de la Reza, Licio da Silva +1
PDS365 is a newly detected rapidly rotating (vsin i = 20 km/s) single low mass giant star which with HD233517 and HD219025 forms a remarkable ensemble of single K giants with the u…
