We present measurements of key protoplanetary disk properties inferred from parametric models of ALMA 12CO spectral line visibilities. We derive gas-disk radii, integrated fluxes,…
Key Physical Parameters Influencing Fragmentation and Multiplicity in Dense Cores of Orion A
Jo-Shui Kao, Hsi-Wei Yen, Shih-Ping Lai
When dense cores in molecular clouds or filamentary structures collapse and form protostars, they may undergo fragmentation and form binary or multiple systems. In this paper, we i…
