Abstract The relative rarity of giant planets around low-mass stars compared with solar-type is a key prediction from the core-accretion planet formation theory. In this paper we report on discovery four gas that transit late K and early M dwarfs. HATS-74Ab (TOI 737b), HATS-75b 552b), HATS-76b 555b), HATS-77b 730b) were all discovered HATSouth photometric survey follow-up using TESS other facil...
