For functions belonging to each of the subclasses $mathcal{M}^{ast }left( alpha right) $ and $mathcal{N}^{ast }left( alpha right) $ of normalized analytic functions in the open unit disk $mathbb{U}$, which are investigated in this paper when $alpha>1,$ the authors derive several subordination results involving the Hadamard product (or convolution) of the associated functions. A number of interesting consequences of some of these subordination results are also discussed.
