ALMA Detects Complex Organic Molecules in Protoplanetary Disk of V883 Orionis

Astronomers have utilized the Atacama Large Millimeter/submillimeter Array (ALMA) to detect complex organic molecules in the protoplanetary disk surrounding the young star V883 Orionis. This discovery provides insights into the chemical processes occurring during the early stages of star and planet formation.

V883 Orionis, located approximately 1,300 light-years from Earth in the Orion constellation, is a young star undergoing an outburst phase, leading to increased luminosity and heating of its surrounding disk. This heating causes the sublimation of icy compounds, releasing complex organic molecules into the gas phase, where they can be detected by ALMA.

Among the molecules identified are methanol, acetone, acetonitrile, acetaldehyde, and methyl formate. These findings suggest that complex organic molecules can form and persist in protoplanetary disks, potentially contributing to the chemical enrichment of nascent planetary systems.

Further observations and analyses are planned to deepen our understanding of the chemical evolution in protoplanetary disks and its implications for the formation of planets and the emergence of life.
