These data are best matched with a white dwarf L8 composite model. For ages ~1 Gyr, the spectral type of the cool secondary is in agreement with the radial velocity determined mass (0.053 /-0.006Msun), and supports an evolutionary scenario in which the brown dwarf survived a previous phase of common envelope evolution which resulted in the formation of this close binary. The brown dwarf is the lowest mass companion to a white dwarf yet found, and the lowest mass object known to have survived a common envelope phase. At 1300K < T < 1400K WD0137-349B is also the coolest known companion to a white dwarf. At a separation a = 0.65Rsun the hemisphere of the brown dwarf facing the 16,500K white dwarf is being heated through irradiation. I will discuss the effects of this additional heating, with particular relevance to those other close binaries with substellar companions, the hot Jupiters, and present new data investigating the temperature differences between the ``day'' and ``night'' sides of the brown dwarf.</font></p> </td> </tr> <tr> <td class="footerleft" width="295" height="80"> <!--webbot bot="Include" u-include="include_copyright.htm" tag="BODY" startspan --> <p style="line-height: 150%; margin-top: 0; margin-bottom: 0">&nbsp;</p> <p style="line-height: 150%; margin-top: 0; margin-bottom: 0"> <font face="Arial">Gemini Science Meeting &copy; 2007</font></p> <p style="line-height: 150%; margin-top: 0; margin-bottom: 0">&nbsp;</p> <!--webbot bot="Include" i-checksum="11746" endspan --></td> <td class="footerright" width="638" height="74"> <!--webbot bot="Include" u-include="include_footer.htm" tag="BODY" startspan --> <hr> <p align="left" style="line-height: 150%; margin-top: 0; margin-bottom: 0"> <font face="Arial" size="1"> <a href="index.html">Home</a>&nbsp; &bull;&nbsp; <a href="info.html">General Information</a>&nbsp; &bull;&nbsp; <a href="sched.html">Schedule</a>&nbsp; &bull;&nbsp; <a href="format.html">Presentation Formats</a>&nbsp; &bull;&nbsp; <a href="participants.html">List of Attendees</a></font></p> <p align="left" style="line-height: 150%; margin-top: 0; margin-bottom: 0"> <font face="Arial" size="1"> <a href="committees.html">Organizing Committees</a> &bull; <a href="registration.html">Registration</a> &bull; <a href="travel.html">Travel Directions</a> &bull; <a href="tourism.html">Tourism in Foz</a> &bull; <a href="http://www.hoteismabu.com.br/eng/mabuthermas/index.php">Hotel </a>&bull; <a href="visa.html">Visa Information</a></font></p> <!--webbot bot="Include" i-checksum="12733" endspan --></td> </tr> </tbody> </table> </div> </body> </html>
