We obtained moderate/low resolution spectroscopy (2/5 AA FWHM) of the microquasar candidate MCQC J162847-4152 (hereafter J1628) on 2003 May 5/6/13 (UT) and June...
Spectroscopic parameters for 451 stars in the HARPS GTO planet search program: Stellar [Fe/H] and the frequency of exo-Neptunes
We present a catalogue with accurate stellar parameters for the 451 stars that compose the HARPS Guaranteed Time Observations (GTO) ``high precision'' sample...
Spectroscopic Parameters for a Sample of Bright Solar-type Stars
We present a new automatic code (ARES) for the determination of equivalent widths of absorption lines present in stellar spectra. We also describe its use for...
Spectroscopic Parameters for a Sample of Metal-rich Solar-type Stars
We present stellar parameters and metallicities for a sample of 64 high metal content stars not known to harbor any planet. This sample provides the reference...
Spectroscopic parameters of 451 HARPS-GTO stars (Sousa+, 2008)
Table 1 contains the atomic parameters and measured solar equivalent widths for FeII and Fe I lines. Table 2 contains the spectroscopic parameters for the 451...
