WINSTON-SALEM, NORTH CAROLINA-- Inspired by glimpses of the turmoil around young stars, a team of astrophysicists has presented a radically new theory of chondrites, stony meteorites that date back to the early days of the solar system. Some researchers have argued that several different processes must have contributed to the making of these objects--a stew of dust, rocks that were "flash melted" and resolidified, and the remains of short-lived radioactive isotopes. But the new theory, presented here at a meeting of the American Astronomical Society last week, holds that all of these ingredients were cooked up by explosive flares and powerful winds near the young sun.
