Protostellar and Protoplanetary Disk Masses in the Serpens Region

Abstract We present the results from an Atacama Large Millimeter/submillimeter Array (ALMA) 1.3 mm continuum and 12 CO ( J = 2 − 1) line survey spread over 10 deg 2 in the Serpens star-forming region of 320 young stellar objects, 302 of which are likely members of Serpens (16 Class I, 35 flat-spectr...

Summary:Abstract We present the results from an Atacama Large Millimeter/submillimeter Array (ALMA) 1.3 mm continuum and 12 CO ( J = 2 − 1) line survey spread over 10 deg 2 in the Serpens star-forming region of 320 young stellar objects, 302 of which are likely members of Serpens (16 Class I, 35 flat-spectrum, 235 Class II, and 16 Class III). From the continuum data, we derive disk dust masses and show that they systematically decline from Class I to flat-spectrum to Class II sources. Grouped by stellar evolutionary state, the disk mass distributions are similar to other young (
