Differential griz photometry of HATS-5

Listed in IVOA Registry (Virtual Observatory)

We report the discovery of HATS-5b, a transiting hot Saturn orbiting a G-type star, by the HATSouth survey.

Description

HATS-5b has a mass of M_p_{approx}0.24M_J_, radius of R_p_{approx}0.91R_J_, and transits its host star with a period of P{approx}4.7634days. The radius of HATS-5b is consistent with both theoretical and empirical models.

The host star has a V-band magnitude of 12.6, mass of 0.94M_{sun}_, and radius of 0.87R_{sun}_. The relatively high scale height of HATS-5b and the bright, photometrically quiet host star make this planet a favorable target for future transmission spectroscopy follow-up observations. We reexamine the correlations in radius, equilibrium temperature, and metallicity of the close-in gas giants and find hot Jupiter-mass planets to exhibit the strongest dependence between radius and equilibrium temperature.

We find no significant dependence in radius and metallicity for the close-in gas giant population.
