Description

We report new Ks-band secondary eclipse observations for the hot-Jupiters WASP-19b and WASP-43b. Using the IRIS2 infrared camera on the Anglo-Australian Telescope (AAT), we measured significant secondary eclipses for both planets, with depths of 0.287-0.020 +0.020 per cent and 0.181-0.027 +0.027 per cent for WASP-19b and WASP-43b, respectively. We compare the observations to atmosphere models from the VSTAR line-by-line radiative transfer code, and examine the effect of C/O abundance, top layer...[Show more]
