Boson Stars and QCD Boson Stars
Usha Kulshreshtha, Sanjeev Kumar, Daya Shankar Kulshreshtha +1
In this talk, we present a review of our work on boson stars in a theory of a massless complex scalar field in the presence of a gauge field and gravity. A sequence of bifur…
Phase Diagrams of Charged Compact Boson Stars
Sanjeev Kumar, Usha Kulshreshtha, Daya Shankar Kulshreshtha +1
Compact boson stars, whose scalar field vanishes identically in the exterior region, arise in a theory involving a {\it massless} complex scalar field with a conical potential, whe…
Charged Compact Boson Stars and Shells in the Presence of a Cosmological Constant
Sanjeev Kumar, Usha Kulshreshtha, Daya Shankar Kulshreshtha
In this work we study the boson stars and boson shells in a theory involving massive complex scalar fields coupled to the U(1) gauge field and gravity in a conical potential in the…

Sanjeev Kumar, Usha Kulshreshtha, Daya Shankar Kulshreshtha +2
In this work we present some new results obtained in a study of the phase diagram of charged compact boson stars in a theory involving a complex scalar field with a conical potenti…
Boson Stars in a Theory of Complex Scalar Fields coupled to Gauge Field and Gravity
Sanjeev Kumar, Usha Kulshreshtha, Daya Shankar Kulshreshtha
We study boson shells and boson stars in a theory of complex scalar field coupled to the gauge field and Einstein gravity with the potential: $V(|Φ|) := \frac{1}{2} m^…
Boson Stars in a Theory of Complex Scalar Field coupled to Gravity
Sanjeev Kumar, Usha Kulshreshtha, Daya Shankar Kulshreshtha
We study boson stars in a theory of complex scalar field coupled to Einstein gravity with the potential: (where and are positive constant…
