Tracking the Evolution of interstellar molecules in the Taurus-1 molecular cloud

(ORDO NEWS) — It has been confirmed that molecules common on Earth can exist in interstellar conditions.

With the development of radio astronomy in recent decades, more than 200 molecules have been identified, including large molecules such as methanol, ethanol, and urea.

The molecular cloud Taurus-1 (Taurus-1) turned out to be a typical astronomical source, in which more than 100 molecules were found.

To study how interstellar molecules are formed and transformed, Dr. Chen Longfei of the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) built a physical-chemical astronomical model with conditions in Taurus-1.

By classifying four different groups of molecules according to their chemical characteristics, the researchers studied the formation, breakdown, and transformation processes among these different groups of molecules.

These processes are an important key to understanding the synthesis and origin of interstellar molecules.

A further comparison between the detected molecular abundances and theoretical model predictions showed that the current astrochemical model could reproduce 71% of the molecules, while for other molecules, improvements in the model were proposed.

The results also showed that the percentage of the mantle mixture of interstellar ice depends on local extinction, which is important for understanding the chemistry of interstellar ice.

“As a major area of ​​development in astronomy worldwide and part of the foundation of astrobiology, astrochemistry is still in its infancy.

This work represents a serious attempt to benchmark models with a chemically rich nearby star-forming cloud,” said NAOC’s Dr. Li Di, Corresponding Author research.
