Binary Formation in Star-forming Clouds with Various Metallicities
Binary Formation in Star-forming Clouds with Various Metallicities
Cloud evolution for various metallicities is investigated by three-dimensional nested grid simulations, in which the initial ratio of rotational to gravitational energy of the host cloud β0 (=10−1 to 10−6) and cloud metallicity Z (=0-Z☉) are parameters. Starting from a central number density of nc = 104 cm−3, cloud evolution …
