| 释义 | dense coredense coreA small centrally condensed molecular cloud, typically of less than 500 solar masses. The central density is high enough to excite lines of ammonia and carbon monosulphide (CS), the latter observed with millimeter-wave telescopes. Many of these cores contain IRAS point sources that appear to be YSOs with luminosities indicating low-mass stars. |
