Cloudy with a chance of exomoons: Hunting for transiting exomoons around a brown dwarf

<ns3:p>This research project investigated the possibility of exomoons around the free-floating brown dwarf 2MASS J10475385+2124234 (2M1047). 2M1047 exhibits auroral emission. Unlike Earth, where aurorae are powered by the Sun, 2M1047 displays aurorae despite not having a parent star. One hypothesis is that these aurorae are driven by a nearby orbiting moon, in a similar way to how Jupiter’s moon Io powers its aurorae. By using spectroscopic and photometric data from the James Webb Space Telescope (JWST), I conducted a three band search running a Gaussian and Transit model to see which one is favoured.</ns3:p>
