Radiative gravastar with Gibbons-Hawking temperature

We study the quantum particle creation in a toy model of spherically symmetric gravitational collapse whose final product is not black hole but gravastar. Precedent studies revealed that even case to form horizonless ultracompact object, thermal radiation named transient Hawking generated at late stage collapse, and sudden stop collapsing motion object causes one or two bursts creation. The very different behavior studied this paper from precedent ones with spectrum gravastar between bursts. temperature same as determined by mass system Gibbons-Hawking de Sitter core inside
