True solar analogues in the open cluster M67
K. Biazzo, L. Pasquini, P. Bonifacio +2
The solar analogues are fundamental targets for a better understanding of our Sun and Solar System. Notwithstanding the efforts, this research is usually limited to field stars. Th…
Testing planet formation theories with Giant stars
Luca Pasquini, M. P. Doellinger, A. Hatzes +4
Planet searches around evolved giant stars are bringing new insights to planet formation theories by virtue of the broader stellar mass range of the host stars compared to the sola…
High-precision wavelength calibration of astronomical spectrographs with laser frequency combs
M. T. Murphy, Th. Udem, R. Holzwarth +8
We describe a possible new technique for precise wavelength calibration of high-resolution astronomical spectrographs using femtosecond-pulsed mode-locked lasers controlled by stab…
Sgr dSph: a bridge between Dwarf Galaxies and DLAs?
L. Sbordone, P. Bonifacio, G. Marconi +2
We present abundances for 12 giants in the Sagittarius Dwarf Spheroidal Galaxy (Sgr dSph) obtained from VLT - UVES spectra. Moving on a short period, polar orbit around the Milky W…
Ca II activity and rotation in F-K evolved stars
L. Pasquini, J. R. de Medeiros, L. Girardi
(Abridged) Ca II H and K high resolution observations for 60 evolved stars in the field and in 5 open clusters are presented. From these spectra chromospheric fluxes are derived, a…
First results of UVES at VLT: abundancesin the Sgr dSph
Piercarlo Bonifacio, Vanessa Hill, Paolo Molaro +3
Two giants of the Sagittarius dwarf spheroidal have been observed with the UVES spectrograph on the ESO 8.2m Kueyen telescope, during the commissioning of the instrument. Sgr 139 h…
