Abstract: For the function solution to the well-known homogeneous Bessel differential equation, we utilized a normalized form of this function to define a certain operator on a subclass of analytic functions. Using this operator, we introduced various subordination properties. We also examined the sufficient starlikeness conditions and provided some estimates for a specific subclass of univalent functions defined in the unit disc.
