For the first time, astronomers see a baby planet shine again from birth

A young gas giant, Wispit 2B, was detected in a multiple rings disc around a sun -shaped star. His active training offers a rare opportunity to study early planetary evolution.

An international team of astronomers, co-directed by researchers from the University of Galway, discovered the surprising discovery of a previously unknown planet.

Found in its first stage of development around a young star similar to our sun, the planet is estimated at around 5 million years and is probably a comparable gas giant in size to Jupiter.

Research, led by the University of Leiden in collaboration with the University of Galway and the University of Arizona, was published in the journal Astrophysical newspaper letters.

This breakthrough was carried out using the Southern European Observatory Very large telescope (THAT‘S VLT), one of the most advanced astronomical installations in the world, located in the Atacama Chile desert.

To mark the publication of the study, the Southern European Observatory – considered as the main organization of international astronomy – elected a striking image of discovery as its image of the week.

The newly identified planet has been designated WISPIT 2B.

A disc of multiple rings dust

Dr. Christian Ginski, lecturer at the School of Natural Sciences, University of Galway, and second author of the study, said: “We used these really short instant observations of many young stars – only a few minutes per object – to determine if we could see a small point of light next to those who are caused by a planet.

“When we saw this disc with multiple rings for the first time, we knew that we should try to see if we could detect a planet in it, so we quickly asked for follow -up observations.”

It is only the second time that a confirmed planet has been detected at this early evolving stage around a young version of our sun. The first was discovered in 2018, by a research team also involving Dr. Ginski.

Wispit 2B is also the first planet detection unambiguously in a disc with multiple rings, making it the ideal laboratory to study the interaction of the planet and subsequent evolution.

Brilliant infrared planet

The planet was captured in a close infrared light – the type of view that someone would see when using night vision glasses – because it is always brilliant and warm after its initial training phase.

The team of the University of Leiden and the University of Galway captured a spectacular and clear image of the young proto-planet integrated into a disc dev. They also confirmed that the planet is in orbit around its host star.

The planet was also detected in the light visible by a team from the University of Arizona using a specially designed instrument. This detection with a wavelength or a specific light of light indicates that the planet always actively accredits gas as it forms its atmosphere.

Wispit 2B was detected as part of a five -year observation research project during which the international team sought to establish whether large giant orbit gas planets are more common around younger or older stars. This led to the unexpected discovery of the new planet.

Dust and discs rich in gas around young stars are the birth cradles of the planets. They may seem quite spectacular with many different structures, such as the rings and the arms in a spiral, which, according to the researchers, are linked to the planets which are formed in them. The disc around Wispit 2B has a radius of 380 astronomical units – about 380 times the distance between the earth and the sun.

Dr. Ginski added: “The capture of an image of these training planets turned out to be extremely difficult, and this gives us a real chance to understand why the thousands of older people exoplanet The systems are so diverse and so different from our own solar system. I think that many of our colleagues who study the training of Planet will closely examine this system in the coming years. »»
