Constraining a possible time-variation of the gravitational constant through “gravitochemical heating” of neutron stars
Published online by Cambridge University Press: 21 October 2010
Abstract
A hypothetical time-variation of the gravitational constant G would produce gravitochemical heating of old (≳ 107−8 yr) neutron stars. It could produce detectable thermal ultraviolet emission from such stars for changes as small as |Ġ/G|~ 10−12 yr−1, comparable to the best existing upper limits from other methods.
