Because of the connection between outflow and accretion seen in low-mass stars, surveys of molecular outflows in high-mass YSOs can shed light on this debate.
因为在低质量恒星形成中外流与吸积相联系,在大质量恒星形成区搜寻分子外流将有助于解决这种争论。

Stars in the process of formation, called young stellar objects or YSOs, are embedded in the compact pinkish nebulae seen here, but are otherwise hidden from the prying eyes of optical telescopes.
