Abstract
Lee-Wick type nontopological solitons (NTS's) are known to arise in a gener ic class of nonminimally coupled theories. Size of these solutions depend u pon the nature and the amount of their associated conserved charge. Such NT S's would have characteristic features and would represent novel astrophysi cal objects. We explore the possibility of having main sequence stars conde nsing around small NTS's. In particular, if such an NTS is embedded in the radiative zone of a star, the exterior attributes could be indistinguishabl e from those of a normal star. Possible application to stellar modeling is explored.
