UA Astronomers See Dust Eruption Around a Young Star

UA Planetary Sciences graduate student Huan Meng, and Steward Observatory astronomers Kate Su and George Rieke, along with former Steward grad student Wiphu Rujopakarn, and their colleagues, have discovered a dust eruption around the young star NGC 2547-ID8. This is the first time a star has been monitored before, during, and after an eruption, thus helping to constrain models of the processes by which earth-like planets form. A plausible story, consistent with the observations and with general ideas for how planets form, is that two large rocky objects collided at high speed, spewing vast amounts of dust into the debris disk.
