We study the Λ ( α ) CDM models with Λ ( α ) being a function of the time-varying fine structure constant α . We give a close look at the constraints on two specific Λ ( α ) CDM models with one and two model parameters, respectively, based on the cosmological observational measurements along with 313 data points for the time-varying α . We find that the model parameters are constrained to be around 1 0 − 4 , which are similar to the results discussed previously but more accurately.
