An abundance analysis of the single-lined spectroscopic binaries with barium stars-like orbital elements: I. Analysis and results

Začs L.; Musaev F.; Bikmaev I.; Alksnis O. (1997)

Detailed abundance analyses have been carried out for 17 single-lined binaries (giants and dwarfs) with orbital elements and mass functions similar to those of barium stars, using high-dispersion CCD spectra and model ...
An abundance analysis of the single-lined spectroscopic binaries with barium stars-like orbital elements: II. The spectroscopic data

Začs L.; Alksnis O.; Musaev F.; Bikmaev I.; Galazutdinov G. (1999)

High-resolution spectroscopic observations are presented for 19 single-lined binaries (giants and dwarfs) with orbital elements and mass functions similar to those of barium stars, two radial velocity non-variable barium ...
Chandra X-ray study confirms that the magnetic standard Ap star KQ Vel hosts a neutron star companion

Oskinova L.M.; Ignace R.; Leto P.; Postnov K.A. (2020)

© ESO 2020. Context. KQ Vel is a peculiar A0p star with a strong surface magnetic field of about 7.5 kG. It has a slow rotational period of nearly 8 years. Bailey et al. (A&A, 575, A115) detected a binary companion of ...
