3488:<br />Now it is thought that planets can even form around super powerful blue supergiants like, Deneb, Rigel, Alnilam, Alnitak, Saiph & even hypergiants like Rho Cassiopiea!!!<br /><br />Me:<br />Hi Andrew, guess we won't really ever know till we can start examining these stars. As doubletruncation pointed out in his response, the technical issues astronomers face with current methods (Transit photometry and radial velocity). Its also theorized in the cases of giants stars that resulted from going supernova, that most of their planetary systems were vaporized during the stellar expansion. However, outer planets could remain I would think. Gas giants at Saturn distance could, over the duration of the stellar expansion phase, loose much of its gaseous atmosphere and any rocky core would be exposed, becoming a rocky planet in the process. <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.
