Context. This paper is the last in a series devoted to the analysis of the binary content of the Hipparcos Catalogue. Aims. The comparison of the proper motions constructed from positions spanning a short (Hipparcos) or long time (Tycho-2) makes it possible to uncover binaries with periods of the order of or somewhat larger than the short time span (in this case, the 3 yr duration of the Hipparcos mission), since the unrecognised orbital motion will then add to the proper motion.

Spectroscopic binaries among Hipparcos M giants , I. Data, orbits, and intrinsic variations

Context. This paper is a follow-up on the vast effort to collect radial velocity data for stars belonging to the Hipparcos survey. Aims. We aim at extending the orbital data available for binaries

Spectroscopic binaries among Hipparcos M giants - II. Binary frequency

Context. This paper is the second in a series devoted to studying the properties of binaries with M giant primaries. Aims. The binary frequency of field M giants is derived and compared with the

FROM BINARIES TO MULTIPLES. I. DATA ON F AND G DWARFS WITHIN 67 pc OF THE SUN

Data on the multiplicity of F- and G-type dwarf stars within 67 pc of the Sun are presented. This distance-limited sample based on the Hipparcos catalog contains 4847 primary stars (targets) with 0.5

Overlooked wide companions of nearby F stars

AIMS: We checked a sample of 545 F stars within 50 pc for wide companions using existing near-infrared and optical sky surveys. METHODS: Applying the common proper motion (CPM) criterion, we detected

True Masses of the Long-period Companions to HD 92987 and HD 221420 from Hipparcos–Gaia Astrometry

The extensive time span of modern radial velocity surveys has made the discovery of long-period substellar companions more common in recent years; however, measuring the true masses of these objects

Radial velocities of K–M dwarfs and local stellar kinematics

Aims. The goal of this paper is to present complete radial-velocity data for the spectroscopically selected McCormick sample of nearby K–M dwarfs and, based on these and supplementary data, to

A SURVEY OF STELLAR FAMILIES: MULTIPLICITY OF SOLAR-TYPE STARS

We present the results of a comprehensive assessment of companions to solar-type stars. A sample of 454 stars, including the Sun, was selected from the Hipparcos catalog with π>40 mas, σπ/π < 0.05,

Stellar and substellar companions of nearby stars from Gaia DR2

Context. The census of stellar and substellar companions of nearby stars is largely incomplete, in particular toward the low-mass brown dwarf and long-period exoplanets. It is, however, fundamentally

New Binaries in the ϵ Cha Association

We present Adaptive Optics-aided speckle observations of 47 young stars in the ϵ Cha association made at the 4 m Southern Astrophysical Research Telescope in the I-band. We resolved 10 new binary

OBSERVATIONS AND ORBITAL ANALYSIS OF THE GIANT WHITE DWARF BINARY SYSTEM HR 5692

We report spectroscopic observations of the red giant star HR 5692, previously known to be a binary system both from other spectroscopic work and from deviations in the astrometric motion detected by

Statistical Constraints for Astrometric Binaries with Nonlinear Motion

Useful constraints on the orbits and mass ratios of astrometric binaries in the Hipparcos catalog are derived from the measured proper motion differences of Hipparcos and Tycho-2 (Δμ), accelerations

How many Hipparcos Variability-Induced Movers are genuine binaries?

Hipparcos observations of some variable stars, and especially of long-period (e.g. Mira) variables, reveal a motion of the photocenter correlated with the brightness variation (variability-induced

Local kinematics of K and M giants from CORAVEL/Hipparcos/Tycho-2 data: Revisiting the concept of superclusters

The availability of the Hipparcos Catalogue has triggered many kinematic and dynamical studies of the solar neighbourhood. Nevertheless, those studies generally lacked the third component of the

A Survey of Proper-Motion Stars. XVI. Orbital Solutions for 171 Single-lined Spectroscopic Binaries

We report 25,563 radial velocity measurements for 1359 single-lined stars in the Carney-Latham sample of 1464 stars selected for high proper motion. For 171 of these, we present spectroscopic orbital

A Substellar Companion to van Maanen 2

The Hipparcos data for the nearest white dwarf van Maanen 2 (=HIP 3829; distance of 4.4 pc) indicate astrometric binarity, in that the proper motion has a large first derivative not accounted for as

Photocentric orbits from a direct combination of ground-based astrometry with Hipparcos. I. Comparison with known orbits

Complementing the Proper Motions of Fundamental Stars catalogue by Gontcharov et al. (CDS, I-266) the pho- tocentric orbits of some FK5/Hipparcos stars are calculated in a direct combination of the

Hipparcos and Tycho Catalogues

This chapter describes various aspects of the Hipparcos and Tycho Catalogues useful for understanding the scientific exploitation considered in subsequent chapters. It describes some of the satellite

On the use of the Hipparcos intermediate astrometric data

With the publication of the Hipparcos cat- alogue, astrometric data of unprecedented quality and quantity has become available, providing parallaxes, po- sitions and proper motions free from

MSC - a catalogue of physical multiple stars

The MSC catalogue contains data on 612 physical multiple stars of multiplicity 3 to 7 which are hierarchical with few exceptions. Orbital periods, angular separations and mass ratios are estimated

We analyze the K band luminosities of a sample of galactic long-period variables using parallaxes measured by the Hipparcos mission. The parallaxes are in most cases re-computed from the Hipparcos
