Detection of Four Intermediate-mass Stars with Cool Companions in Low Mass Ratio Eclipsing Binaries

The Astrophysical Journal
According to the core fragmentation and dynamical capture theories of binary formation, binaries tend to form with nearly equal masses. The detection of intermediate-mass binaries with low mass ratios challenges these theories, as such binaries may form ...

Orbital Modulation Induced by a Third Component in the Overcontact Binary V0554 Dra

The Astrophysical Journal
We present the first comprehensive photometric and spectroscopic analysis of the overcontact eclipsing binary V0554 Dra. By simultaneously modeling multiband light curves and radial velocity data using the Wilson–Devinney code, we determine that the ...

TYC 3340-2437-1: A Quadruple System with a Massive Star

The Astrophysical Journal
Hierarchical massive quadruple systems are ideal laboratories for examining the theories of star formation, dynamical evolution, and stellar evolution.

The Binary Fraction of B-type Runaway Stars from LAMOST DR8

The Astrophysical Journal
Runaway stars are defined as stars that depart from their birth clusters at high peculiar velocities. There are two main mechanisms for the formation of runaway stars, i.e., the binary-supernova scenario (BSS) and the dynamical ejection scenario (DES ...

The Crucial Role of Third Body in Formation and Evolution of Contact Binary Systems: Evidence from CY Ari and IK Lyn

The Astrophysical Journal
CY Ari and IK Lyn are two eclipsing binary systems that share the same spectral type but exhibit significantly different metallicities. Based on the Wilson–Devinney (W-D) method, the first photometric solutions are obtained by analyzing the new complete ...

The Magnified Waltz: Simulating Light Curves of Binary Stars Passing Through Microcaustics in Strong Lensing Galaxy Clusters

The Astrophysical Journal
Individual stars located near the caustics of galaxy clusters can undergo extreme magnification when crossing microcaustics, rendering them observable even at cosmological distances. Though most massive stars are likely to reside in binary systems rather
