摘要:

我们报告了WASP对两个系外行星系统的调查发现,每个系外行星系统都由一颗彗星大小的行星经过一颗11等(V)的主序星组成。WASP-104 b的轨道周期为1.75 d,而WASP-106 b的轨道周期为9.29 d,是通过从地面观测凌日发现的行星中第四长的。每颗行星的质量都比木星大(WASP-104 b的质量是$1.27 \pm 0.05 \mathrm{M_{Jup}}$,而WASP-106 b的质量是$1.93 \pm 0.08 \mathrm{M_{Jup}}$)。这两颗行星都比木星稍大,WASP-104和WASP-106的半径分别为$1.14 \pm 0.04$和$1.09 \pm 0.04 \mathrm{R_{Jup}}$。在这两个系统中都没有发现明显的轨道偏心率,虽然这在短周期WASP-104 b的情况下并不奇怪,但在WASP-106 b的情况下却很有趣,因为许多其他类似的行星都有偏心轨道。

英文摘要:

We report the discovery from the WASP survey of two exoplanetary systems, each consisting of a Jupiter-sized planet transiting an 11th magnitude (V) main-sequence star. WASP-104b orbits its star in 1.75 d, whereas WASP-106b has the fourth-longest orbital period of any planet discovered by means of transits observed from the ground, orbiting every 9.29 d. Each planet is more massive than Jupiter (WASP-104b has a mass of $1.27 \pm 0.05 \mathrm{M_{Jup}}$, while WASP-106b has a mass of $1.93 \pm 0.08 \mathrm{M_{Jup}}$). Both planets are just slightly larger than Jupiter, with radii of $1.14 \pm 0.04$ and $1.09 \pm 0.04 \mathrm{R_{Jup}}$ for WASP-104 and WASP-106 respectively. No significant orbital eccentricity is detected in either system, and while this is not surprising in the case of the short-period WASP-104b, it is interesting in the case of WASP-106b, because many otherwise similar planets are known to have eccentric orbits.
