IPAC Astronomy Lunch Seminar

Extrasolar moon may be frequent, temperate abodes for life and their detection would not only have astrobiological significance but would also greatly further our understanding of planet/moon formation theories. For the first time, the detection of a transiting planet-moon system is moving from the realms of theory to observation due to the unprecedented photometric precision being achieved by Kepler. In this talk, I will discuss how we might find a transiting exomoon, exploring both the dynamical effects (such as transit timing variations) and the eclipse effects (such as mutual eclipses) which may be observable. It is shown that Kepler is capable of finding Earth-sized and -mass moons. I will close by introducing a new systematic program to search these elusive objects, which will shed light on the frequency of large moons around extrasolar planets.
