The next five years present a truly unique opportunity in the history of planetary astrophysics. For the first time, we have the observational techniques, the theoretical models, and a sufficient number of known exoplanets orbiting nearby stars to spectroscopically characterize a wide diversity of planets—ranging from hot giant planets to temperate Earth-sized planets in the habitable zone of their host stars. My group is currently in a unique position to make the next big leaps in this rapidly growing field of exoplanet characterization because I recently developed a novel theoretical modeling technique to interpret spectroscopic observations of exoplanets (Benneke 2016) and I was awarded several unprecedented observational programs using the Hubble Space Telescope (334 hours), the Spitzer Space Telescope (217 hours), and the Keck observatories (11 nights) to obtain the necessary data for this characterization. Benefitting from this unique starting position, I will establish a research group at Université de Montréal that will be among the worldwide leading groups in the characterization of exoplanet atmospheres. Highlights of my near-term work will be:

未来五年将是行星天体物理学史上一个真正独特的机会。这是第一次，我们有观测技术，理论模型，以及足够数量的已知系外行星绕着附近的恒星运行，以光谱表征各种各样的行星-从热的巨行星到温带地球大小的行星，位于其宿主恒星的可居住区。我的团队目前处于一个独特的位置，可以在这个快速发展的系外行星表征领域实现下一个重大飞跃，因为我最近开发了一种新颖的理论建模技术来解释系外行星的光谱观测（Benneke 2016）和我被授予了几个前所未有的观测计划，使用哈勃太空望远镜（334小时），斯皮策太空望远镜（217小时）和凯克天文台（11晚），以获得必要的数据，这一特点。受益于这一独特的起点，我将在蒙特利尔大学建立一个研究小组，该小组将成为系外行星大气层表征的全球领先小组之一。我近期工作的重点是：
