Orbits of Six Triple Systems

The Astronomical Journal
Joint analysis of position measurements and radial velocities of six triple stellar systems is conducted to determine their inner and/or outer orbits. Accumulation of such data is needed to study the architecture of stellar hierarchies and its relation ...

KIC 6464285: A Solar-type Eclipsing Binary in a Hierarchical Triple System with Quasiperiodic Out-of-eclipse Modulations

The Astrophysical Journal
We present the first detailed analysis of the solar-type triple system KIC 6464285. Combining long-term, high-precision photometry from Kepler, the Transiting Exoplanet Survey Satellite, and the Zwicky Transient Facility with low-resolution spectra from ...

Detached Post-Algol Eclipsing Binaries Caught between Case A and Case AB Mass Transfer

The Astrophysical Journal
For 60 yr, stellar evolutionary models have predicted that intermediate-mass stars slightly contract on the terminal-age main sequence (TAMS) as they exhaust hydrogen in their convective cores, producing the main-sequence (MS) hook on the Hertzsprung ...

The Evolution of Compact Binary Star Systems

Living Reviews in Relativity, 2006
We review the formation and evolution of compact binary stars consisting of white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Binary NSs and BHs are thought to be the primary astrophysical sources of gravitational waves (GWs) within the ...

Runaway Neutron Stars from Massive Binary Stellar Systems

reservedAs far as we know, most massive stars live in binary systems. Depending on the initial masses of the two stars, metallicity, and orbital separation, the system can experience different phases.

Interacting binary stars

, 1978
Interacting Binary Stars deals with the development, ideas, and problems in the study of interacting binary stars. The book consolidates the information that is scattered over many publications and papers and gives an account of important discoveries ...
