Abstract
In this paper we investigate an interesting subclass () of starlike functions in the unit disk . The class was introduced by Kargar et al. [R. Kargar, A. Ebadian and J. Sok\'o{\l}, {\it On Booth lemniscate and starlike functions}, Anal. Math. Phys. (2017) DOI: 10.1007/s13324-017-0187-3] which is strongly related to the Booth lemniscate. Some geometric properties of this class of analytic functions including, radius of starlikeness of order (), the image of when , an special example and estimate of bounds for are studied.
