HATS-39b, 40b, 41b and 42b transit data
Listed in IVOA Registry (Virtual Observatory)
We report the discovery of four transiting hot Jupiters from the HATSouth survey: HATS-39b, HATS-40b, HATS-41b, and HATS-42b.
Description
These discoveries add to the growing number of transiting planets orbiting moderately bright (12.5<=V<=13.7) F dwarf stars on short (2-5d) periods. The planets have similar radii, ranging from 1.33^+0.29^_-0.20_R_J_ for HATS-41b to 1.58^+0.16^_-0.12_R_J_ for HATS-40b.
Their masses and bulk densities, however, span more than an order of magnitude. HATS-39b has a mass of 0.63+/-0.13M_J_, and an inflated radius of 1.57+/-0.12R_J_, making it a good target for future transmission spectroscopic studies. HATS-41b is a very massive 9.7+/-1.6M_J_ planet and one of only a few hot Jupiters found to date with a mass over 5M_J_.

This planet orbits the highest metallicity star ([Fe/H]=0.470+/-0.010) known to host a transiting planet and is also likely on an eccentric orbit. The high mass, coupled with a relatively young age (1.34^+0.31^_-0.51_Gyr) for the host star, is a factor that may explain why this planet's orbit has not yet circularized.
