Brown dwarfs are objects in the mass gap between stars and planets. Lacking the contaminating light from a host star, observations of brown dwarfs can provide insight into what to expect from future observations of massive, Jupiter-like exoplanets. One curious feature of brown dwarfs is their changing brightness, which is thought to be caused by changing patterns of clouds in their atmospheres or - in some instances - the presence of powerful analogs of Jupiter's aurorae. In this PhD you will use data from the James Webb Space Telescope to study the variability of a nearby brown dwarf, providing our best look yet at this puzzling phenomenon.

褐矮星是恒星和行星之间质量差距的物体。由于缺乏来自主星星的污染光，对褐矮星的观测可以为未来对大质量、类彗星系外行星的观测提供深入的了解。褐矮星的一个奇怪的特征是它们的亮度变化，这被认为是由大气中云的变化模式引起的，或者在某些情况下，是木星极光的强大类似物的存在。在这个博士学位中，你将使用詹姆斯·韦伯太空望远镜的数据来研究附近一颗褐矮星的变化，为我们提供最好的视角来观察这种令人困惑的现象。
