摘要：
As part of a comprehensive centimeter radio continuum survey of deeply embedded young stellar objects in Bok globules, we present deep Very Large Array 3.6 cm continuum observations toward a sample of seven Bok globules. A total of 21 radio sources were detected above a 5 sigma sensitivity threshold of 0.1 mJy. Five of these sources are located within the optical extent of the globules and may correspond to very deeply embedded protostars. We have also identified one bona fide starless globule (CB 24).
