Preventing stars from eating their young

摘要

Writing in this issue, Benitez-Llambay et al. (page 63) report computer simulations that may throw light on why the Solar System and a substantial fraction of exoplanetary systems have gas-giant planets that are separated from their host stars by distances of at least Earth's distance from the Sun. Gas giants are planets such as Jupiter (Fig. 1) and Saturn, with masses tens to hundreds of times that of Earth and consisting mostly of gas.
