The Evolution of Wide Binary Stars [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2009
We study the orbital evolution of wide binary stars in the solar neighborhood due to gravitational perturbations from passing stars. We include the effects of the Galactic tidal field and continue to follow the stars after they become unbound. For a wide

Widely separated binary systems of very low mass stars [PDF]

open access: yesAstronomische Nachrichten, 2005
In this paper we review some recent detections of wide binary brown dwarf systems and discuss them in the context of the multiplicity properties of very low-mass stars and brown dwarfs.Comment: 2 pages, 1 figure (new version with minor corrections); to ...

Wide binary stars with non-coeval components

open access: yesOpen Astronomy, 2022
Abstract We have the estimated masses of components of visual binaries from their spectral classification. We have selected pairs in which the less massive component looks more evolved. Spectral observations of some of these pairs were made, and at least one pair, HD 156331, was confirmed to have components of different ages.

Fast rotating stars resulting from binary evolution will often appear to be single [PDF]

open access: yes, 2010
Rapidly rotating stars are readily produced in binary systems. An accreting star in a binary system can be spun up by mass accretion and quickly approach the break-up limit.

Extremely Wide Pairs in the World of Binary Stars

open access: yesAstronomy Reports, 2023
Abstract This article raises the question of the possibility of identifying stellar pairs in which one of the components belongs to the family of near-nuclear central S-stars and the other belongs to a population of hypervelocity stars (HVSs).

Wide-binary Stars Formed in the Turbulent Interstellar Medium

open access: yesThe Astrophysical Journal Letters, 2023
Abstract The ubiquitous interstellar turbulence regulates star formation and the scaling relations between the initial velocity differences and the initial separations of stars. We propose that the formation of wide binaries with initial separations r in the range ∼103 au ≲ r ≲ 105 au is a natural consequence of star formation in the ...

The Role of Mass and Environment in Multiple Star Formation: A 2MASS Survey of Wide Multiplicity in Three Young Associations [PDF]

open access: yes, 2007
We present the results of a search for wide binary systems among 783 members of three nearby young associations: Taurus-Auriga, Chamaeleon I, and two subgroups of Upper Scorpius.
