More over\, although no compact objects consisting of fundamental scalar bosons have been observed\, there is\, as of now\, no fundamental principle ruli ng out the existence of compact objects consisting of scalar fields. In th is seminar\, I will present an introduction to a subset of the compact obj ects comprising of scalar fields that are known as boson stars. I will dis cuss various astrophysical properties of boson stars and show how those ca n markedly differ from the properties of neutron stars. Furthermore\, I wi ll highlight the mathematical formalism underlying a proper description of these stars and briefly outline the first results I have obtained on the topic. Finally\, contingent on time constraints\, I will briefly elucidate the possible connection between boson stars and dark matter.\n LOCATION:https://researchseminars.org/talk/UTPhysics/5/ END:VEVENT END:VCALENDAR
