Scientists have made an amazing discovery by detecting the presence of shock gas in the protoplanetary disk around the young star TW Hydraewhich could indicate the formation of a planet four times the mass of Earth. This groundbreaking discovery offers a rare glimpse into the mysterious early stages of planet formation.
Baby planets: hidden in plain sight?
Planet formation is a complicated dance, and although we know that planets form in disks around young stars, much remains a mystery. The problem? These Infant worlds are often surrounded by dense, dusty gas that obscures their vision. huge gas giants The planets we see today probably grew by accumulating gas and dust around rocky cores, like Jupiter and Saturn, and cutting significant gaps in the surrounding disks. But how can we observe this if the planets themselves are invisible?
It turns out that even though we cannot see the planet, we can cosmic fingerprintsWhen a developing planet consumes gas and dust, it emits outflows into its surroundings that produce strong Shock waves that trigger the formation of special molecules like sulfur monoxide (SO). These molecules can tell astronomers where to find baby planets. And the best part? We may have found one of these newborns!
TW Hydrae: Ground Zero of Planet Formation
One of the best places to search Planet formation is TW Hydrae, an 8 million year old star that is only 200 light years away. This star has next known protoplanetary diskwhich from our perspective almost appears like a target.
Recent discoveries have shown Gaps in this record at 26 and 42 Astronomical Units (AU), indicating the presence of not only one, but two planetseach with an estimated mass of 4 Earths. And there are more! A mysterious lump Gas at 52 AU indicates another growing planetary body.
Now a team led by Tomohiro Yoshida of the National Astronomical Observatory of Japan has discovered a crucial clue: a Emissions sheet of sulfur monoxide molecules, exactly 42 AU away from TW Hydrae.
A planet was suspected to exist right here! With the help of highly developed ballistic outflow modellingThe researchers showed that the SO outflow was only influenced by the presence of a growing planet about four times the mass of the Earth.
A new era of discoveries awaits us
With this smoking gun of planet formation in hand, Yoshida’s team is not giving up. They plan to continue their search for more molecular evidenceand looked in particular for silicon monosulfide (SiS) emissions, which could confirm the existence of even more hidden planets.
Their work paves the way for a deeper understanding how planets like Earth, Jupiter, and even mysterious new worlds are formed.
