Resonant Trapping of the Moving Groups G18-39 and G21-22 in the Galactic Halo
W. J. Schuster, J. G. Fernández-Trincado, E. Moreno
The 3D Galactic orbits of stars in the two groups G18-39 and G21-22 pertaining to the Galactic halo have been computed in a Galactic potential including a Galactic bar. The orbits…
The Gaia spectrophotometric standard stars survey -II. Instrumental effects of six ground-based observing campaigns
G. Altavilla, S. Marinoni, E. Pancino +16
The Gaia SpectroPhotometric Standard Stars (SPSS) survey started in 2006, it was awarded almost 450 observing nights, and accumulated almost 100,000 raw data frames, with both phot…
uvby- photometry of solar twins: the solar colors, model atmospheres, and the Teff and metallicity scales
J. Melendez, W. J. Schuster, J. S. Silva +3
Solar colors have been determined on the uvby- photometric system to test absolute solar fluxes, to examine colors predicted by model atmospheres as a function of stellar parame…
HD 207331 a new Scuti star in the Cygnus field: discovery and follow-up observations
L. Fox-Machado, W. J. Schuster, C. Zurita +2
Preliminary results on the discovery and follow-up observations of a new Scuti pulsator in the Cygnus field are presented. The variability of the star HD 207331 was detected wh…
Observational signatures for depletion in the Spite plateau: solving the cosmological Li discrepancy?
J. Melendez, L. Casagrande, I. Ramirez +2
We present Li abundances for 73 stars in the metallicity range -3.5 < [Fe/H] < -1.0 using improved IRFM temperatures (Casagrande et al. 2010) with precise E(B-V) values obtained mo…
UBV(RI)_C photometry of the open clusters Be 15, Be 80, and NGC 2192
M. T. Tapia, W. J. Schuster, R. Michel +4
The three open clusters Be 15, Be 80, and NGC 2192 have been observed using CCD UBV(RI)_C photometry at the San Pedro Mártir Observatory, México within the framework of our open-cl…
