Abstract

We obtain a (5+1)-dimensional global flat embedding of the Gibbons-Maeda-Garfinkle-Horowitz-Strominger spacetime in the Einstein frame and a (5+2)-dimensional global flat embedding in the string frame. We show that the local free-fall temperatures for freely falling observers in each frame are finite at the event horizons, while the local temperatures for fiducial observers are divergent. We also observe that the local free-fall temperatures differ between the two frames.
