Orbits of 171 single-lined spectroscopic binaries
25,563 radial velocity measurements are reported for 1359 single-lined stars in the Carney-Latham sample of 1464 stars selected for high proper motion; for 171 of these,... -
Apsidal motion in double stars. I.
A catalog of 128 double stars with measured periods of apsidal motion is compiled. Besides the apsidal periods, the orbital elements of binaries and physical parameters of... -
NIR photometric studies of R Canis Majoris
We present here the first light curves of the peculiar Algol binary system R Canis Majoris obtained in the near-infrared photometric bands J and K. The light curves are fitted... -
Micrometer measures of double stars
Micrometer measures of 795 double stars made with the 26 inch (0.66m) refractor of the US Naval Observatory from 1984 to 1990 are presented. Cone search capability for table... -
MACHO Variables V.
We report the characteristics of 611 eclipsing binary stars in the Large Magellanic Cloud found by using the MACHO Project photometry database. The sample is magnitude limited,... -
Orbit and mass for 22 visual binaries
This paper presents orbits and masses for 22 visual double stars, partly derived using their last observations made with the speckle camera PISCO. For 13 of them we have... -
Catalog of binary UV Ceti stars
A catalogue of nearby UV Ceti type flare stars in (137) visual binary systems is presented in the form of two separate tables of information. The catalogue has developed from... -
Double star measurements 1995-1997
We present speckle observations of 48 double and multiple stars observed with the 2-meter ``Telescope Bernard Lyot'' (TBL) in December 1995, January 1997 and June 1997. Angular... -
9 visual double stars orbital elements
Orbital elements and ephemerides for 9 visual double stars are given. Cone search capability for table J/A+AS/132/253/table (General parameters) -
Double stars measurements
624 Micrometer Measurements of 224 pairs with a 32.5 cm Cassegrain, 719 Measurements of 310 double stars with a 360 mm Newtonian are given. Cone search capability for table... -
COU 247, ADS 3672 & ADS 15182 observations
This paper presents new orbits for two visual double stars COU 247 (CCDM 00095+1907) and ADS 3672 (STT 95, CCDM 05055+1948) and a revised orbit for ADS 15182 (A 772, CCDM... -
RVs of binaries black hole/Sun-like stars
Stellar-mass black holes descend from high-mass stars, most of which had stellar binary companions. However, the number of those binary systems that survive the binary evolution... -
Newborn Be star system
Many classical Be stars acquire their very rapid rotation by mass and angular-momentum transfer in massive binaries. Short-lived intermediate-phase objects have only been... -
Bulk metallicity of giant planets around M stars
Determination of the bulk metallicity of giant exoplanets is essential in order to constrain their formation and evolution pathways and to compare them to the Solar System.... -
Hot sub-luminous and binaries variability
Hot sub-luminous stars represent a population of stripped and evolved red giants located at the Extreme Horizontal Branch (EHB). Since they exhibit a wide range of variability... -
TESS OBAF-type eclipsing binaries
Eclipsing binaries are crucial for understanding stellar physics, allowing detailed studies of stellar masses, radii, and orbital dynamics. Recent space missions like the... -
VELOCE II. spectroscopic binary Cepheids
Classical Cepheids provide valuable insights into the evolution of stellar multiplicity among intermediate-mass stars. Here, we present a systematic investigation of... -
Detached eclipsing binaries lifetime of starspots
Tidal deformation breaks the axisymmetric structure of stars, and this may affect stellar activity. This effect has been demonstrated in theoretical analyses and simulations,... -
TOI-178 light curves
The TOI-178 system consists of a nearby, late-K-dwarf with six transiting planets in the super-Earth to mini-Neptune regime,with radii ranging from ~1.1 to 2.9R_{Earth}_ and... -
New binary systems in Magellanic Clouds
Period change studies offer a novel way to probe the evolution and dynamics of Cepheids. While evolutionary period changes have been well studied both observationally and...
