Can a naked singularity be formed during the gravitational collapse of a Janis-Newman-Winicour solution?
Xiao Yan Chew, Il Gyeong Choi, Hyuk Jung Kim +1
The Janis-Newman-Winicour (JNW) spacetime possesses a naked singularity, although it represents an exact particle-like solution to the Einstein-Klein-Gordon theory with a massless…
