MPI for Gravitational Physics<p>On this day fourteen years ago, on 6 April 2011, the second radio pulsar discovered with <span class="h-card" translate="no"><a href="https://academiccloud.social/@einsteinathome" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>einsteinathome</span></a></span> was published.</p><p>Our distributed computing project had started almost exactly two years earlier to analyze data from the Arecibo radio telescope with the help of tens of thousands of volunteers.</p><p>This second discovery was special: the pulsar orbits the common center of mass with a white dwarf in just 9.4 hours and it belongs to a rare “species”.</p><p>ℹ️ <a href="https://www.aei.mpg.de/191149/einstein-home-detects-unusual-stellar-pair" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">aei.mpg.de/191149/einstein-hom</span><span class="invisible">e-detects-unusual-stellar-pair</span></a></p><p>📄 <a href="https://iopscience.iop.org/article/10.1088/2041-8205/732/1/L1" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">iopscience.iop.org/article/10.</span><span class="invisible">1088/2041-8205/732/1/L1</span></a></p><p>At the time, it was assumed that this pulsar could be used to observe relativistic effects.
