Using the ARO 12-m telescope, astronomers have investigated a young starless core known as Lynds 1521E (or L1521E). The study resulted in the detection of complex organic molecules in this object. The finding is detailed in a paper April 15 on the arXiv pre-print repository.
Starless cores are dense, cold regions within interstellar molecular clouds. They represent the earliest observable stage of low-mass star formation. Observations show that even in such cold environments, complex organic molecules can be present. Finding these molecules in starless cores could help us better understand the processes of stellar formation and evolution.
L1521E is a dynamically and chemically young starless core in the Taurus Molecular Cloud, one of the two known in this cloud. It has a modest central density of around 200,000−300,000 cm−3 and it is assumed that it can only have existed at its present density for less than 100,000 years, which makes it one of the youngest starless cores so far detected and an excellent object to study how complex organic molecules form.
