Black Holes with Scalar Hair in (2+1) dimensions
Yoshitaka Degura, Kenji Sakamoto, Kiyoshi Shiraishi
Nonrotating and rotating black hole soltuions in (2+1) dimensions are studied in a model including a real scalar field with a simple potential coupled to gravity.

Boson Stars with Large Self-interaction in (2+1) dimensions: an Exact Solution
Kenji Sakamoto, Kiyoshi Shiraishi
An exact solution for a nonrotating boson star in (2+1) dimensional gravity with a negative cosmological constant is found. The relations among mass, particle number, and radius of…
