Description/Abstract
We estimate the maximal deformation that can be sustained by a rotating neutron star with a crystalline
color-superconducting quark core. Our results suggest that current gravitational-wave data from the Laser
Interferometer Gravitational-Wave Observatory have already reached the level where a detection would
have been possible over a wide range of the poorly constrained QCD parameters. This leads to the
nontrivial conclusion that compact objects do not contain maximally strained color crystalline cores
drawn from this range of parameter space. We discuss the uncertainties associated with our simple model
and how it can be improved in the future.
