We analyze 5108 AFGKM stars with at least five high-precision radial velocity points, as well as Gaia and Hipparcos astrometric data, utilizing a novel pipeline developed in...

We have determined spectroscopic orbital elements for 13 systems - 10 single-lined binaries and three double-lined binaries. For the three binaries with previously published...

Orbital elements of 18 visual binaries are computed using the measurements collected in the Fourth Catalog of Interferometric Measurements of Binary Stars; 15 orbits are...

A new relative orbit solution with new dynamical masses is determined for the nearby white dwarf-red dwarf pair 40 Eri BC. The period is 230.29+/-0.68 years. It is predicted to...

Results are presented for 299 speckle interferometric observations of double stars, obtained in 2008 at the USNO Flagstaff Station using the 1.55m Kaj Strand Astrometric...

Results are presented for 353 speckle interferometric observations of double stars, obtained in 2003 and 2004 at the USNO Flagstaff Station using the 1.55m Kaj Strand...

The first orbit for visual binary A 1529 and improved orbital elements for HU 610 and COU 2031 based on new speckle measurements with the 6m telescope of the Special...

We present 6907 differential photometric observations in the V filter, as well as 52 radial velocities from spectroscopic observations of the detached, eccentric 7.97day...

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...

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...

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...

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...

Orbital elements and ephemerides for 9 visual double stars are given. Cone search capability for table J/A+AS/132/253/table (General parameters)

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...

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...

The number of discovered exoplanets now exceeds 5500, allowing statistical analyses of planetary systems. Multi-planet systems are mini-laboratories of planet formation and...

Binary systems constitute a valuable astrophysics tool for testing our understanding of stellar structure and evolution. Systems contain- ing at least one oscillating component...

All neutron star progenitors in neutron-star High-Mass X-ray Binaries (NS HMXBs) undergo a supernova event that may lead to a significant natal kick impacting the motion of the...

We analyze solutions drawn from the recently published posterior distribution of the TRAPPIST-1 system, which consists of seven Earth-size planets appearing to be in a resonant...

The change in the argument of periastron of eclipsing binaries, that is, the apsidal motion caused by classical and relativistic effects, can be measured from variations in the...
