We discover HATS-36b (EPIC 215969174b, K2-145b), an eccentric (e = 0.105 ± 0.028) hot Jupiter with a mass of 3.216 ± 0.062 MJ and a radius of 1.235 ± 0.043 RJ, which transits a solar-type G0V star (V = 14.386) in a -day period. We also refine the properties of three previously discovered HATSouth transiting planets (HATS-9b, HATS-11b, and HATS-12b) and search the K2 data for TTVs and additional transiting planets in these systems. In addition, we also report on a further three systems that remain as Jupiter-radius transiting exoplanet candidates. These candidates do not have determined masses, however pass all of our other vetting observations. Finally, we report on the 18 candidates that we are now able to classify as eclipsing binary or blended eclipsing binary systems based on a combination of the HATSouth data, the K2 data, and follow-up ground-based photometry and spectroscopy. These range in periods from 0.7 day to 16.7 days, and down to 1.5 mmag in eclipse depths. Our results show the power of combining ground-based imaging and spectroscopy with higher precision space-based photometry, and serve as an illustration as to what will be possible when combining ground-based observations with TESS data.Development of the HATSouth project was funded by NSF MRI grant NSF/AST-0723074. Operations have been supported by NASA grants NNX09AB29G, NNX12AH91H, and NNX17AB61G, and follow-up observations receive partial support from grant NSF/AST-1108686.

Funding for the K2 mission is provided by the NASA Science Mission directorate. The K2 observations presented here were obtained through the GO program, with analysis supported by NASA grant NNX16AE68G. This work is based on observations made with ESO Telescopes at the La Silla Observatory. This paper also uses observations obtained with facilities of the Las Cumbres Observatory Global Telescope.
