Revisiting the mass- and radius-luminosity relations for FGK main-sequence stars
João Fernandes, Ricardo Gafeira, Johannes Andersen
Scaling relations are very useful tools for estimating unknown stellar quantities. Within this framework, eclipsing binaries are ideal for this goal because their mass and radius a…
Abundances and kinematics of carbon-enhanced metal-poor stars in the Galactic halo*; A new classification scheme based on Sr and Ba
Camilla J. Hansen, Terese T. Hansen, Andreas Koch +4
Carbon-enhanced metal-poor (CEMP) stars span a wide range of stellar populations, from bona fide second-generation stars to later forming stars that provide excellent probes of, e.…
HE 0017+0055 : A probable pulsating CEMP-rs star and long-period binary
A. Jorissen, T. Hansen, S. Van Eck +6
A radial-velocity monitoring of the Carbon-Enhanced Metal-Poor (CEMP) star HE 0017+0055 over 8 years with the Nordic Optical Telescope and Mercator telescopes reveals variability w…
New Abundances From Very Old Stars
T. Hansen, C. J. Hansen, N. Christlieb +3
Metal-poor stars provide the fossil record of Galactic chemical evolution and the nucleosynthesis processes that took place at the earliest times in the history of our Galaxy. From…
Towards stellar effective temperatures and diameters at one per cent accuracy for future surveys
L. Casagrande, L. Portinari, I. S. Glass +8
The apparent size of stars is a crucial benchmark for fundamental stellar properties such as effective temperatures, radii and surface gravities. While interferometric measurements…
Age -- Metallicity relation in the MCs clusters (Based on observations made with the Danish 1.54 m and ESO 3.6m Telescopes at La Silla Observatory, Chile)
E. Livanou, A. Dapergolas, M. Kontizas +5
Aims: To investigate a possible dependence between age and metallicity in the Magellanic Clouds (MCs) from a study of small open star clusters, using Strömgren photometry. Our goal…
