发现由金子、钻石构成的行星。
Alien Worlds will explore the techniques that are used to discover and characterize the thousands of planets (called exoplanets) known outside of our solar system.

课程概况

Have you ever wondered about planets in other solar systems? Have you ever thought about the possibility of life elsewhere in the Universe? For the first time in human history, we know that planets around other stars not only exist, but are common!

Alien Worlds focuses on the search and characterization of planets orbiting other stars (called extrasolar planets or “exoplanets”). Over the course of nine modules, we will learn some of the techniques used to discover the thousands of known exoplanets and will discuss how we can use basic scientific tools to characterize the sizes, masses, compositions, and atmospheres of exoplanets. We will also learn about the diversity of stars in the Galaxy to understand how stellar properties affect exoplanet detection techniques and influence planetary formation and habitability.

In addition to the exploration of exoplanets, students in Alien Worlds will gain a basic understanding of light, gravity and motion, and be introduced to some of the most extreme life on planet Earth. We will hear from experts at the forefront of exoplanet science and interact with other participants and instructors through social media and online tools. Students will leave Alien Worlds with a better understanding of their place in the Universe and the skills to comprehend the wealth of new discoveries surrounding the countless worlds around distant stars.

主讲教师

Andrew West
Andrew West is an Assistant Professor in the Department of Astronomy at Boston University. West’s major research interests center around using low-mass stars (the smallest, yet most numerous stars in the Milky Way) to understand the structure and evolution of the Milky Way galaxy, the environments that host exoplanets, and various processes on the stars themselves. Professor West has a strong commitment to his role as a scholar-teacher and has been the instructor for Alien Worlds at Boston University since 2011. He was recently awarded an NSF CAREER grant and a Cottrell Scholarship for his research and teaching endeavors, including his efforts to increase the diversity of Astronomy and other science fields.

Sadia Hoq
Sadia Hoq, course graduate coordinator, is a 4th year Ph.D. candidate in the Boston University Department of Astronomy. Her research focuses on studying the magnetic field in the disk of the Milky Way, particularly how it affects the formation of stars. Sadia has worked with Professor West as the head Teaching Fellow for BU’s Alien Worlds course since its inception in 2011.

Kolby Weisenburger
Kolby Weisenburger, course undergraduate assistant, is a senior Astronomy and Physics major at Boston University. Kolby is a member of Professor West’s research group and studies the details of how stars regulate their activity (flares and star spots) and spin down (rotate more slowly) as they age.

Brandon Harrison
Brandon Harrison is a second year PhD candidate at the Boston University Astronomy Department. His research focuses on studying dark matter around galaxies by using computer simulations. Brandon has worked with Professor West in the past to teach this course to undergraduates and also has experience helping to teach higher level astronomy courses.
