Abstract:
Accurate mass, radius, and abundance determinations from binaries
provide important information on stellar evolution, fundamental to
central fields in modern astrophysics and cosmology.
Within the long-term Copenhagen Binary Project, we aim to obtain
high-quality light curves and standard photometry for double-lined
detached eclipsing binaries with late A, F, and G type main-sequence
components, needed for the determination of accurate absolute
dimensions and abundances, and for detailed comparisons with results
from recent stellar evolutionary models.
Between March 1985 and July 2007, we carried out photometric
observations of AD Boo, HW CMa, SW CMa, V636 Cen, VZ Hya, and WZ Oph
at the Stromgren Automatic Telescope at ESO, La Silla. We obtained
complete uvby light curves, ephemerides, and standard uvbyβ
indices for all six systems.
Description:
