UGA's Song receives Webb Telescope support to observe low-mass stars

Inseok Song, associate professor of astronomy in the University of Georgia Franklin College of Arts and Sciences department of physics and astronomy, has received a grant from the James Webb Space Telescope (JWST). Song's JWST program, "JWST Mid-IR Observations of Warm Debris Disks around Nearby M-dwarfs", will observe 19 M-type stars, the lowest mass stars that are the most common in the Universe.  "M-dwarf stars are the most common type…

New research challenges long-standing paradigm on planet formation

Two theories of planet formation have long-dominated astronomy - the first theory, “core accretion,” posits that planets grow slowly from particles of dust ultimately forming pebbles, then boulders, which coalesce to form planets over tens of millions of years.  The second theory – “gravitational instability,” in which planets form quickly from direct collapse of gas and dust, requiring hundreds to thousands of years instead – received new…
