We report the discovery of four short period extrasolar planets transiting moderately bright stars from photometric measurements of the HATSouth network coupled to additional spectroscopic and photometric follow-up observations .
While the planet masses range from 0.26 to 0.90 M _ { J } , the radii are all approximately a Jupiter radii , resulting in a wide range of bulk densities .
The orbital period of the planets range from 2.7d to 4.7d , with HATS-43b having an orbit that appears to be marginally non-circular ( e = 0.173 \pm 0.089 ) .
HATS-44 is notable for a high metallicity ( [ Fe / H ] = 0.320 \pm 0.071 ) .
The host stars spectral types range from late F to early K , and all of them are moderately bright ( 13.3 < V < 14.4 ) , allowing the execution of future detailed follow-up observations .
HATS-43b and HATS-46b , with expected transmission signals of 2350 ppm and 1500 ppm , respectively , are particularly well suited targets for atmospheric characterisation via transmission spectroscopy .
