The influence of binary interactions on infrared passbands of populations.
ZHANG F., LI L. and HAN Z.
Abstract (from CDS):
By comparing the results for binary stellar populations with (Model A) and without (Model B) binary interactions, we show that the inclusion of binary interactions makes the stellar mass of a binary stellar population smaller (∼3.6-4.5 per cent during the past 15Gyr), magnitudes greater (except U, ∼ 0.18mag at the most), colours bluer (∼0.15mag for V - K at the most) and mass-to-light ratios greater (∼0.06 for K band) except those in the U and B passbands at higher metallicities. Binary interactions make the V magnitude less sensitive to age, and R and I magnitudes more sensitive to metallicity.
Given an age, the absolute values of the differences in the stellar mass, magnitudes and mass-to-light ratios (except those in the U and B bands) between Models A and B reach a maximum at Z = 0.0001, i.e. the effects of binary interactions on these parameters reach a maximum, while the differences in some colours reach a maximum at Z ∼ 0.01-0.0004. In contrast, the absolute value of the difference in the stellar mass is minimal at Z = 0.03; those in the U,B,V magnitudes and the mass-to-light ratios in the U and B bands reach a minimum at Z ∼ 0.01-0.004.
