Planets around active stars
J. Setiawan, P. Weise, Th. Henning +8
We present the results of radial velocity measurements of two samples of active stars. The first sample contains field G and K giants across the Red Giant Branch, whereas the secon…
Physical parameters of evolved stars in clusters and in the field from line-depth ratios
K. Biazzo, L. Pasquini, A. Frasca +6
We present a high-resolution spectroscopic analysis of two samples of evolved stars selected in the field and in the intermediate-age open cluster IC 4651, for which detailed measu…
Deriving temperature, mass and age of evolved stars from high-resolution spectra. Application to field stars and the open cluster IC 4651
K. Biazzo, L. Pasquini, L. Girardi +6
We test our capability of deriving stellar physical parameters of giant stars by analysing a sample of field stars and the well studied open cluster IC 4651 with different spectros…
Metallicity Gradient And The Hybrid Formation Scenario For Early-Type Galaxies
Ricardo L. C. Ogando, Marcio A. G. Maia, Cristina Chiappini +3
We present radial gradients of the Lick index Mg2 for 40 early-type galaxies. In plots of Grad(Mg2) versus mass indicators, such as log(sigma), the lower boundary of the points dis…
