Evolution of magnetic fields in stars across the upper main sequence: I. Catalogue of magnetic field measurements with FORS 1 at the VLT

Hubrig, S.; North, P.; Schöller, M. +1 more

To properly understand the physics of Ap and Bp stars it is particularly important to identify the origin of their magnetic fields. For that, an accurate knowledge of the evolutionary state of stars that have a measured magnetic field is an important diagnostic. Previous results based on a small and possibly biased sample suggest that the distribu…

Contribution to the study of binaries with spectral types F, G, K, and M XI. Orbital elements of three red-giant spectroscopic binaries: HR 1304, HR 1908, and HD 126947

Griffin, R. F.; Prieur, J. -L.; Carquillat, J. -M.

The orbital elements of three red-giant single-lined spectroscopic binaries, HR 1304, HR 1908 and HD 126947, are presented. They are obtained from observations made with two photoelectric spectrometers of CORAVEL type, the first located at the Observatoire de Haute-Provence and the second at the Cambridge Observatories. HR 1304 and HR 1908 are kno…

First ground-based photometry and light-curve analysis of the eccentric eclipsing binary V744 Cas

Bulut, İ.; Erdem, A.; Bakis, V. +3 more

The first ground-based BVR photometric observations of the recently discovered eclipsing binary V744 Cas are presented. From these measurements, timings for two primary and one secondary minima have been calculated. The light curves of the system were analyzed by using the Wilson-Devinney program. The analysis shows that the system is detached wit…
