A high-precision chemical abundance analysis of the HAT-P-1 stellar binary: Constraints on planet formation

Liu, Fan; Asplund, Martin; Ramirez, I; Yong, David; Melendez, Jorge

Description

We present a high-precision, differential elemental abundance analysis of the HAT-P-1 stellar binary based on high-resolution, high signal-to-noise ratio Keck/HIRES (High Resolution Echelle Spectrometer) spectra. The secondary star in this double system is known to host a transiting giant planet while no planets have yet been detected around the primary star. The derived metallicities ([Fe/H]) of the primary and secondary stars are identical within the errors: 0.146 ± 0.014 dex (σ = 0.033 dex)...[Show more]
