| contents | Photometric analysis of KIC 9272276 (K9272), a low-mass contact binary system, is
presented. We find it to be an example of an extreme low mass ratio system that satisfies the current
theoretical criteria for a potential red-nova progenitor. V band photometry of the system was modelled
using the Wilson-Devenney code and we find the system to be in marginal contact with a mass ratio of
0.081. The estimated mass of the primary component is one solar mass and the theoretical instability
mass ratio range, accounting for both metallicity and age, is well above the modelled mass ratio at
0.09- 0.101. We find no evidence of a potential third light contamination and discuss other findings
confirming our analysis. |
