18Feb

Dr. Joel Green's vivid descriptions of the observations of young stars bring to life the details of the star formation process.  Joel answers questions about how long it takes planets to form, and how to look for disks around stars.  The disks around stars are hotter closer into the star, and colder farther away from the star.  Using infrared-sensitive detectors connected to telescopes, astronomers like Joel and cohost DJ Gigayear discover properties of disks surrounding young stars.  We break down the different classes and types of protostars.  Joel describes his work with the Spitzer Space Telescope and the Herschel Space Telescope.  One of the things Joel is trying to figure out is the effect of chaotic sudden burst events seen in stars like FU Orionis.
