Orbits of globular clusters computed with dynamical friction in the Galactic anisotropic velocity dispersion field

Edmundo Moreno, José G. Fernández-Trincado, Angeles Pérez-Villegas +2

We present a preliminary analysis of the effect of dynamical friction on the orbits of part of the globular clusters in our Galaxy. Our study considers an anisotropic velocity disp…

Effect of orbital trapping by bar resonances in the local U-V velocity field

Edmundo Moreno, José G. Fernández-Trincado, William J. Schuster +2

The effects in the local U-V velocity field due to orbital trapping by bar resonances have been studied computing fifteen resonant families in a non-axisymmetric Galactic potential…

G112-43/44: A metal-poor binary star with a unique chemical composition and kinematics like the Helmi streams

P. E. Nissen, J. S. Silva-Cabrera, W. J. Schuster

G112-43/44, alias BD+00_2058 A and B, is a metal-poor ([Fe/H] = -1.3) wide-orbit binary star with extreme kinematics. We use high-precision determinations of the chemical compositi…

The Gaia spectrophotometric standard stars survey -- IV. Results of the absolute photometry campaign

G. Altavilla, S. Marinoni, E. Pancino +18

We present Johnson-Kron-Cousins BVRI photometry of 228 candidate spectrophotometric standard stars for the external (absolute) flux calibration of Gaia data. The data were gathered…

The Average Physical Properties of A-G Stars Derived from uvby-H Strömgren-Crawford Photometry as the Basis for a Spectral-Classification Synthetical Approach

G. Dalle Mese, O. López-Cruz, W. J. Schuster +2

We have revisited and updated the Strömgren colour and colour-index distributions of A, F and early G-type main sequence stars. For this aim, we selected 7054 dwarf stars al…

UBVRI-KC Photometry of NGC~2323 and NGC~2539 Open Clusters

Inci Akkaya Oralhan, Raul Michel, William J. Schuster +3

The open clusters NGC 2323 and NGC 2539 have been analysed using CCD UBV(RI)KC photometric data, observed at the San Pedro Martir Observatory. Cluster memberships have been determi…
