Constraints on the Size of Extra Dimensions from the Orbital Evolution of the Black-Hole X-Ray Binary XTE J1118+480

Tim Johannsen

In a universe of the Randall-Sundrum type, black holes are unstable and emit gravitational modes in the extra dimension. This leads to dramatically shortened lifetimes of astrophys…

Constraints on the Size of Extra Dimensions from the Orbital Evolution of Black-Hole X-Ray Binaries

Tim Johannsen, Dimitrios Psaltis, Jeffrey E. McClintock

One of the plausible unification schemes in physics considers the observable universe to be a 4-dimensional surface (the "brane") embedded in a higher-dimensional curved spacetime…
