Older worlds with planetary companions may be the place to find the most ancient life in the galaxy, according to a new study. (techtimes.com)
Due in part of discoveries of planetary companions around this Sun - like star, 47 Ursae Majoris became one of the top 100 target stars for NASA's proposed Terrestrial Planet Finder (TPF), which is now indefinitely delayed. (members.nova.org)
We first generate a stellar field with planetary companions based on radial velocity discoveries, use a planetary evolution model assuming a variable fraction of heavy elements to compute the characteristics of transit events, then apply a detection criterion that includes both statistical and red noise sources.
