Contact tracing of binary stars: Pathways to stellar mergers

open access: yes
Stellar mergers are responsible for a wide variety of phenomena such as rejuvenated blue stragglers, highly magnetised stars, spectacular transients, iconic nebulae, and stars with peculiar surface chemical abundances and rotation rates.

V1309 Scorpii: merger of a contact binary

open access: yes, 2011
Context. Stellar mergers are expected to take place in numerous circumstences in the evolution of stellar systems. In particular, they are considered as a plausible origin of stellar eruptions of the V838 Mon type.

V717 Andromedae: An Active Low Mass Ratio Contact Binary

open access: yesThe Open Journal of Astrophysics
Multi-band photometric analysis of the contact binary V717 Andromedae (V717 And) is presented. The system is found to be an extreme low mass ratio system (q = 0.197) with high inclination (i = 84.5 deg), moderate degree of contact (27%) and near equal ...

Light Curve Study of the Eclipsing Contact Binary V2477 Cyg

open access: yes, 2016
V2477 Cyg is a short-period eclipsing binary star system in the Cygnus constellation. Its light curve indicates that the two stars are so close as to be in physical contact with each other.

Merger of Noncompact Binaries: Triggering Mechanisms and Merger Timescales of W UMa Contact Binaries

open access: yesThe Astrophysical Journal
The merger of noncompact binaries can produce a variety of significant celestial objects, including blue stragglers, luminous red novae, and others. However, several key details of the merger of noncompact binaries remain unclear.

Using MESA to Test Our Theory of Contact Binary Star Evolution

open access: yes, 2020
A contact binary star system consists of two stars orbiting each other so closely that they share a common atmosphere (Figure 1). Nearly 1% of stars like our sun are contact binaries, yet there is not a comprehensive model of their lives.

FS Lupi: a contact binary in poor thermal contact

open access: yes, 1987
The UBV photoelectric lightcurves of the eclipsing binary FS Lupi, observed at ESO, La Silla, during 1982-1984, have been analyzed with a Roche-model-based lightcurve synthesis method.
