There are people working actively on tests of GR and alternative theories using X-ray binaries (see <a href="http://relativity.livingreviews.org/Articles/lrr-2008-9/" rel="nofollow">this very nice review by Dimitrios Psaltis</a>) and they are well appreciated by the Astrophysics community. <br />Future X-ray missions like LOFT or Athena, scheduled for the 2020s, should improve significantly our sensitivity to orbital period derivatives and other features that can be used to test relativistic effects (iron line broadening, high-frequency quasi-periodic oscillations, and so on.). See <a href="http://arxiv.org/abs/1202.6069" rel="nofollow">one of the many examples of possible applications</a>.<br />Athena is currently being dropped by ESA in favor of a mission to Jupiter, and the risk is that we might wait much longer to perform these tests, but <a href="http://fs6.formsite.com/ATHENA2022/form1/index.html" rel="nofollow"> we hope to convince ESA to change their mind</a>.Anonymoushttps://www.blogger.com/profile/15512918933046704020noreply@blogger.com
