Candidate spectroscopic binaries in SDSS
We have examined the radial velocity data for stars spectroscopically observed by the Sloan Digital Sky Survey (SDSS) more than once to investigate the incidence of... -
Journal of all RVs of eps Per primary
A detailed analysis of a large collection of electronic spectra from three observatories, together with radial velocities published earlier, were used to derive a new ephemeris... -
Companions to close spectroscopic binaries
We have surveyed a sample of 165 solar-type spectroscopic binaries (SB) with periods from 1 to 30 days for higher-order multiplicity. 62 targets have been observed with the NACO... -
V360 Lac spectroscopy
We include existing photometric and spectroscopic material with new observations in a detailed study of the Be+F binary V360 Lac. We used the programs FOTEL and KOREL to derive... -
Radial velocities of beta Cep
We present the radial-velocity data of both components of the double-lined spectroscopic binary Beta Centauri, whose lines are blended throughout the orbit. The radial-velocity... -
Radial velocities of DW Car
We have studied the high-mass short-period detached eclipsing binary DW Carinae using high-resolution echelle spectroscopy and photoelectric Stroemgren uvby light curves. We... -
UBV photometry of HD 143418
After a serendipitious discovery that HD 143418 is a light variable, we analyzed numerous UBV observations and Hipparcos H_p_ magnitudes transformed to Johnson V to find out... -
Radial velocity in multiple systems
We want to improve the knowledge of orbits, physical parameters and statistics of nearby multiple systems. Radial velocities were measured with a correlation spectrometer during... -
Radial velocities of HD 209625
The goal is to test the structure of hot metallic stars, and in particular the structure of a near-surface convection zone using asteroseismic measurements. Indeed, stellar... -
UV Flux distributions of gamma Dor stars
It seems that the recently identified class of pulsating stars, the gamma Dor type-variables, includes objects with different metal abundances and a large percentage of... -
Orbital elements of 156 spectroscopic binaries
We report on a comprehensive, long-term monitoring programme aiming to improve our knowledge of such binary systems. We monitored the radial velocities of 1309 red giants in 187... -
Procyon (alpha CMi) radial velocities
The data represent report a 9-night asteroseismic observation program conducted in January 2007 with the new spectrometer SOPHIE at the OHP 193-cm telescope, on the F5 IV-V... -
White dwarf-red dwarf binaries in the SDSS
To reduce contamination by more distant sources, such as quasars, we have selected candidate white dwarf-red dwarf binaries from the catalogue of proper motion stars drawn from... -
Radial velocities of 3 RasTyc new triple system
During the study of a large set of late-type stellar X-ray sources, we discovered a high fraction of multiple systems. In this paper we investigate the orbital elements and... -
Spectral analysis of 636 SDSS WD-M binaries
We present a catalog of 857 WD-M star binaries from the Sloan Digital Sky Survey (SDSS), most of which were previously identified by other authors, and the results of our... -
Radial velocities of SB with M giant
This paper is a follow-up of the vast effort to collect radial velocity data for stars belonging to the Hipparcos survey. We aim at extending the orbital data available for... -
Radial velocities of 9 O-type stars
We present the results obtained from a long-term spectroscopic campaign to study the multiplicity of O-type stars in both the young open cluster NGC 2244 and the Mon OB2... -
Search for brown-dwarf companions of stars
The discovery of 9 new brown-dwarf candidates is reported. New CORALIE radial velocities of 6 previously-known hosts of potential brown-dwarf companions are presented. We use... -
Radial velocities in the globular NGC 2808
The formation mechanism of hot horizontal branch (HB) stars is still one of the most uncertain points of stellar evolution theories. In the past decade, models based on their... -
Priority targets for the MUCHFUSS project
The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) aims at finding sdBs with compact companions like supermassive white dwarfs...
