Abstract
As a result of a radial velocity follow-up of OGLE planetary transit candidates in Carina, we report the discovery of two new transiting planets with very short orbital periods: OGLE-TR-113 with $m=1.35 \pm 0.22~M_{\rm Jup}$, $r=1.08^{+0.07}_{-0.05}~R_{\rm Jup}$, P=1.43 days, and OGLE-TR-132 with $m=1.01\, \pm\, 0.31~M_{\rm Jup}$, $r=1.15^{+0.80}_{-0.13}~R_{\rm Jup}$, P=1.69 days. These detections bring to three the number of known "very hot Jupiter" (Jovian exoplanets like OGLE-TR-56 with periods around 1.5 days). This indicates that the accumulation of periods around 3 days found in radial velocity surveys does not reflect an absolute limit.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
