Fundamental parameters of the eclipsing binary TU Canis Majoris.


Abstract (from CDS):

We present a spectroscopic and photometric study of the eclipsing binary TU Canis Majoris aimed to obtain their fundamental stellar parameters and evolutionary stage. Our results indicate that the masses, radii, temperatures, and luminosities for the primary and secondary stars are: M1=1.761±0.012 M, M2=1.144±0.010 M, R1=1.553±0.002 R, R2=1.075±0.002 R, T1=8014±151 K, T2=6060±100 K, L1=8.913 ±0.695 L, and L2=1.396±0.097 L. We estimate an age for the system of τ=2.11±0.24×108 years, and a distance of d = 324.81±12.86 pc. In addition, we note that none of the components has filled their respective Roche lobe and both are on the main sequence.
