摘要:

我们报告发现的HATSouth调查的HATS-3b,一个凌日系外行星轨道V=12.4 F-矮星。HATS-3b的周期P = 3.5479d,质量Mp = 1.07MJ,半径Rp = 1.38RJ。考虑到行星的半径、主星的亮度和恒星的自转速度(vsini = 9.0km/s),这个系统将成为未来观测的一个有趣目标,以测量罗斯特-麦克劳克林效应并确定其自旋轨道对准。我们详细介绍了低/中分辨率侦察光谱,我们现在正在使用的处理大量过境行星候选人的HATSouth调查。我们发现,这一重要的步骤,发现行星产生logg和Teff参数的精度适合有效的候选人审查,以及有效地识别恒星质量食双星的径向速度半振幅低至1公里/秒。

英文摘要:

We report the discovery by the HATSouth survey of HATS-3b, a transiting extrasolar planet orbiting a V=12.4 F-dwarf star. HATS-3b has a period of P = 3.5479d, mass of Mp = 1.07MJ, and radius of Rp = 1.38RJ. Given the radius of the planet, the brightness of the host star, and the stellar rotational velocity (vsini = 9.0km/s), this system will make an interesting target for future observations to measure the Rossiter-McLaughlin effect and determine its spin-orbit alignment. We detail the low/medium-resolution reconnaissance spectroscopy that we are now using to deal with large numbers of transiting planet candidates produced by the HATSouth survey. We show that this important step in discovering planets produces logg and Teff parameters at a precision suitable for efficient candidate vetting, as well as efficiently identifying stellar mass eclipsing binaries with radial velocity semi-amplitudes as low as 1 km/s.
