HATS-4b: A dense hot Jupiter transiting a super metal-rich G star
We report the discovery by the HATSouth survey of HATS-4b, an extrasolar planet transiting a V = 13.46 mag G star. HATS-4b has a period of P ˜ 2.5167 days, mass of Mp ˜ 1.32 MJup, radius of Rp ˜ 1.02 RJup, and density of ?p = 1.55 ± 0.16 g cm-3 ˜ 1.24 ?Jup. The host star has a mass of 1.00 M?, a rad...

| description | We report the discovery by the HATSouth survey of HATS-4b, an extrasolar planet transiting a V = 13.46 mag G star. HATS-4b has a period of P ˜ 2.5167 days, mass of Mp ˜ 1.32 MJup, radius of Rp ˜ 1.02 RJup, and density of ?p = 1.55 ± 0.16 g cm-3 ˜ 1.24 ?Jup. The host star has a mass of 1.00 M?, a radius of 0.92 R?, and a very high metallicity [Fe/H]=0.43 ± 0.08. HATS-4b is among the densest known planets with masses between 1 and 2 MJ and is thus likely to have a significant content of heavy elements of the order of 75 M?. In this paper we present the data reduction, radial velocity measurements, and stellar classification techniques adopted by the HATSouth survey for the CORALIE spectrograph. We also detail a technique for simultaneously estimating vsin i and macroturbulence using high resolution spectra. © 2014. The American Astronomical Society. All rights reserved. |
