Investigation Limb darkening for short period AB Andromeda eclipsing binary star
Polytechnic Journal, 2023 This work deal with characterizing the limb darkening coefficients for the short period binary stars AD Andromeda to determine the size, luminosities and masses of the Individual stars as well as orbital size and orientation of the binary system ...

THE OCCURRENCE OF WIDE-ORBIT PLANETS IN BINARY STAR SYSTEMS [PDF]
The Astrophysical Journal, 2014 The occurrence of planets in binary star systems has been investigated via a variety of techniques that sample a wide range of semi-major axes, but with a preponderance of such results applicable to planets with semi-major axes less than a few AU. We utilize a new method -- the presence or absence of heavy elements in the atmospheres of white dwarf ...

Galactic perturbations on the population of wide binary stars with exoplanets [PDF]
Astronomy & Astrophysics, 2017 Aims. The aim of this work is to study the dynamical effects of the Galaxy on binary star systems with physical and orbital charac- teristics similar to those of the population of known wide binary stars with exoplanets. As secondary goal we analyse the possible consequences on the stability of a hypothetical planetary system orbiting one of the ...

PSF-based Analysis for Detecting Unresolved Wide Binaries
The Astrophysical Journal Supplement Series, 2023 Wide binaries play a crucial role in analyzing the birth environment of stars and the dynamical evolution of clusters. When wide binaries are located at greater distances, their companions may overlap in the observed images, becoming indistinguishable ...

Statistical Modeling and Analysis of Wide Binary Star Systems [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractPost-main-sequence (MS) mass loss causes orbital separation amplification in fragile (i.e. common proper motion) binary star systems. Components typically have separations around ∼1000 AU. Such wide pairs experience negligible tidal interactions and mass transfer between companions; thus they evolve as two separate but coeval stars.

Space-Based Photometry of Binary Stars: From Voyager to TESS
Universe, 2021 Binary stars are crucial laboratories for stellar physics, so have been photometric targets for space missions beginning with the very first orbiting telescope (OAO-2) launched in 1968.

The origin of very wide binary stars
, 2011 A large population of fragile, wide (> 1000 AU) binary systems exists in the Galactic field and halo. These wide binary stars cannot be primordial because of the high stellar density in star forming regions, while formation by capture in the Galactic field is highly improbable.

Formation of Massive and Wide First-star Binaries in Radiation Hydrodynamic Simulations
The Astrophysical Journal, 2023 Abstract We study the formation of Population III stars by performing radiation hydrodynamic simulations for three different initial clouds extracted from cosmological hydrodynamic simulations. Starting from the cloud collapse stage, we follow the growth of protostars by accretion for ∼105 yr until the radiative feedback from the ...

Binary frequency of planet-host stars at wide separations [PDF]
Astronomy & Astrophysics, 2014 The aim of the project is to improve our knowledge on the multiplicity of planet-host stars at wide physical separations. We cross-matched approximately 6200 square degree area of the Southern sky imaged by the Visible Infrared Survey Telescope for Astronomy (VISTA) Hemisphere Survey (VHS) with the Two Micron All Sky Survey (2MASS) to look for wide ...
