ABSTRACT:
The vast majority of close-in planets are either massive hot Jupiters capable of holding their atmosphere against the stellar photoevaporation or small rocky planets completely drained by the stellar radiation. We observe an unexpected dearth of highly irradiated Neptune- and Saturn-like planets orbiting their host star in less than 4-10 days, called “Hot Neptune Desert”. In this talk, I will present our recent findings from uniformly vetting 250 hot Neptune TESS candidates using a two-step vetting technique, as well as discuss a cutting-edge approach to examine the problem under a new perspective. I will also discuss how the PLATO mission may enhance our understanding of the Hot Neptunes.
