AJ latest papers http://stacks.iop.org/1538-3881 Founded in 1849 by Benjamin A. Gould, the AJ publishes original astronomical research, with an emphasis on significant scientific results derived from observations, including descriptions of data capture, surveys, analysis techniques, and astrophysical interpretation. It takes a broad view of astronomy, extending from the solar system to observational cosmology with a tradition of papers discussing dynamical processes. The AJ serves an international community that includes authors, scientists and students through efficient and accessible communication of the science and associated techniques. en-gb Copyright © IOP Publishing 2009 Thu, 01 Jan 1970 00:00:00 GMT Thu, 01 Jan 1970 00:00:00 GMT http://syndication.iop.org/about/ custserv@iop.org (Customer Services) The Astronomical Journal http://images.iop.org/website-logos/ejs_logo.png http://stacks.iop.org/ Pre-Discovery Observations of CoRoT-1b and CoRoT-2b with the BEST Survey http://stacks.iop.org/1538-3881/139/i=1/a=53?rss=2.0 Author(s): H.
