Boson star and dark matter

Understand

Bound states of complex scalar fields (boson stars) have long been proposed as possible candidates for the dark matter in the universe.

• Considerable work has already been done to study various aspects of boson stars.
• In the present work, assuming a particular anisotropic matter distribution, we solve the Einstein-Klein-Gordon equations with a cosmological constant to obtain bosonic configurations by treating the problem geometrically.
• The results are then applied to problems covering a wide range of masses and radii of the boson stars and the relevant self interaction parameters are calculated.
