Tidal effects in close binary stars [PDF]
This review addresses the question of what can be learned about the stellar interiors from the study of the tidal effects in close binary stars.

Research on close binary systems has continued at a high level during the past triennium, although the rate of growth is noticeably slower – probably reflecting the cutbacks in funds to which many of us are subject. There have also been changes of emphasis within the field, which are commented on in the pages that follow.

New spectroscopic binary companions of giant stars and updated metallicity distribution for binary systems [PDF]
We report the discovery of 24 spectroscopic binary companions to giant stars. We fully constrain the orbital solution for 6 of these systems. We cannot unambiguously derive the orbital elements for the remaining stars because the phase coverage is ...

New Close Binary Central Stars of Planetary Nebulae from Gaia DR3 Epoch Photometry. [PDF]
Close binary interactions perform a key role in the formation and shaping of planetary nebulae (PNe). However only a small fraction of Galactic PNe are known to host close binary systems.

Super slowly spinning stars in close binaries
ABSTRACT Stars in short-period binaries typically have spins that are aligned and synchronized with the orbit of their companion. In triple systems, however, the combination of spin and orbital precession can cause the star’s rotation to evolve to a highly misaligned and sub-synchronous equilibrium known as a Cassini state. We identify a

CLOSE BINARY SYSTEMS ON LATE EVOLUTIONARY STAGES
Observational and theoretical progress in investigations of close binary stars allow to understand the nature and evolution of many types of close binary systems containing peculiar components: Wolf-Rayet stars, white dwarfs neutron stars and black holes.

Gravitoastronomy with neutron stars [PDF]
Recent advances in gravitational wave detectors mean that we can start to make astrophysically important statements about the physics of neutron stars based on observed upper limits to their gravitational luminosity.

THE CLOSE BINARY FRACTION OF DWARF M STARS [PDF]
We describe a search for close spectroscopic dwarf M star binaries using data from the Sloan Digital Sky Survey (SDSS) to address the question of the rate of occurrence of multiplicity in M dwarfs. We use a template fitting technique to measure radial velocities from 145,888 individual spectra obtained for a magnitude-limited sample of 39,543 M dwarfs.

Discovery of four close binary stars in Sagittarius [PDF]
This Note is the second in a series of Notes where we report new variable stars discovered during our extensive CCD monitoring program of the black hole binary V4641 Sgr (SAX J1819.3-2525)(Orosz et al., 2001).
