The N2K Consortium. II. A Transiting Hot Saturn around HD 149026 with a Large Dense Core
Open accessAbstract
Doppler measurements from Subaru and Keck have revealed radial velocity variations in the V = 8.15, G0 IV star HD 149026 consistent with a Saturn-mass planet in a 2.8766 day orbit. Photometric observations at Fairborn Observatory have detected three complete transit events with depths of 0.003 mag at the predicted times of conjunction. HD 149026 is now the second-brightest star with a transiting extrasolar planet. The mass of the star, based on interpolation of stellar evolutionary models, is 1.3 ± 0.1 M ☉ ; together with the Doppler amplitude K 1 = 43.3 m s -1 , we derive a planet mass M sin i = 0.36 M J and orbital radius 0.042 AU. HD 149026 is chromospherically inactive and metal-rich with spectroscopically derived [Fe/H] = +0.36, T eff = 6147 K, log g = 4.26, and v sin i = 6.0 km s -1 . Based on T eff and the stellar luminosity of 2.72 L ☉ , we derive a stellar radius of 1.45 R ☉ . Modeling of the three photometric transits provides an orbital inclination of 85 3 ± 1 0 and (including the uncertainty in the stellar radius) a planet radius of (0.725 ± 0.05) R J . Models for this planet mass and radius suggest the presence of a ~67 M ⊕ core composed of elements heavier than hydrogen and helium. This substantial planet core would be difficult to construct by gravitational instability.

“For example, Queloz et al. (2001) and Paulson et al. (2004) have shown that photospheric features were the source of periodic RV variations in the young G0 V star HD 166435 and in several Hyades dwarfs.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
