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…
The tidal effects on the lithium abundance of binary systems with giant component
J. M. Costa, L. da Silva, J. D. do Nascimento +1
We analise the behavior of lithium abundance as a function of effective temperature, projected rotational velocity, orbital period and eccentricity for a sample of 68 binary system…
The Spectral Energy Distribution of the Seyfert galaxy Ton S180
T. J. Turner, P. Romano, S. B. Kraemer +14
We present spectral results from a multi-satellite, broad-band campaign on the Narrow-line Seyfert 1 galaxy Ton S180 performed at the end of 1999. We discuss the spectral-energy di…
A New Association of Post-T Tauri Stars Near The Sun
Carlos A. O. Torres, Licio da Silva, Germano R. Quast +2
Observing ROSAT sources in 20 x 25 deg centered at the high latitude active star ER Eri, we found evidences for a new young nearby association (~30Myr at~60pc), the Horologium Asso…
