The Fundamental Parameters and Evolutionary Status of V454 Aurigae

Abstract

Eclipsing binary systems have a unique feature that enables scientists to obtain precise fundamental star parameters, which opens up a greater area of astrophysics studies. In this study, we derived the fundamental parameters, evolutionary status, and birthplace of V454 Aur in the Galaxy by combining radial velocity, photometric, and spectral energy distribution data. We have updated the ephemerides and period of V454 Aur as 2458850.80136 +0.00001 −0.00001 and 27.0198177 +0.0000003 −0.0000003, respectively. We obtain 1.173 +0.016 −0.016 𝑀⊙ and 1.203 +0.022 −0.026 𝑅⊙ for the primary component and 1.045 +0.015 −0.014 𝑀⊙ and 0.993 +0.034 −0.027 𝑅⊙ for the secondary component. The effective temperatures for the components were accurately determined via SED data as 6250 +150 −150 K and 5966 +109 −89 K for the primary component and secondary component, respectively. The metallicity of the components is derived from evolutionary tracks, which implies a slightly higher metallicity than Solar metallicity. According to the analysis, the components of V454 Aur are in the main sequence. Our distance calculation for the system is 65.07 +2 −3 pc and is in excellent agreement with Gaia astrometric data, which is 65.07 +0.09 −0.09 pc. The current age of the system is 1.19 +0.08 −0.09 Gyr, and it will start mass transfer between components in 5 Gyr from now on. Dynamical orbital analysis shows that V454 Aur follows a boxy pattern around the Galactic centre and is a member of the thin-disc component of the Galaxy. Considering the age and metallicity of this system, it was found to have formed just outside the Solar circle.
