Abstract:
In October 2017, a paper (https://arxiv.org/pdf/1707.08563.pdf) was released discussing a potential exomoon candidate, Kepler-1625b I. The exomoon was characterized as roughly the size of Neptune, orbiting a gas giant. Recently, a paper (https://arxiv.org/pdf/1904.10618.pdf) independently studies the transit data and finds no significant detection of an exomoon. This talk will explore: (1) what are the methods and models employed in both works; (2) how in the world do you form a Neptune size moon; and (3) what are the take-away messages from these two independent studies. Spoiler: Kepler-1625b I is probably not a space station.
