摘要：

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 +/- 0.22 M-Jup, r = 1.08(-0.05)(+0.07) R-Jup, P = 1.43 days, and OGLE-TR-132 with m = 1.01 +/- 0.31 M-Jup, r = 1.15(-0.13)(+0.80) R-Jup, = 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.
