UV radiation from massive stars prevents formation of Jupiter-like planet

29 February 2024

An international team of scientists including Alessandra Candian and Annemieke Petrignani of the University of Amsterdam has used space telescope Hubble and the ALMA observatory to show that UV radiation from massive stars can prevent planets from forming. The researchers publish their findings March 1 in Science.
The protoplanetary disk d203-506 (bottom left) suffers so much from the UV radiation from heavy stars in the Trapezium cluster (top right) that a Jupiter-like planet-in-formation cannot form.

The team studied the Orion Nebula, a known stellar nursery. The astronomers found that a Jupiter-like planet-in-formation in protoplanetary disk d203-506 could not form because heavy stars in the Trapezium cluster nearby produce intense UV radiation. The UV radiation causes gas to be ejected from the protoplanetary disk. This leaves too little gas to form a planet.
