Scientists hunting exoplanets have developed a clever new strategy to find migrating worlds that are hidden



Researchers will use data from the ALMA telescope to study migration patterns of exoplanets in distant star systems.

A telescope capable of capturing dust rings from faraway star systems could come a long way Practical as scientists have developed a new strategy to help them find hidden worlds and the birthplace of exoplanets in As these rings take place, scientists believe that they can now learn more about exoplanets.

As Live Science British scientists are detailing how small planets within these rings should move and how they can monitor the movement of these exoplanets, even though the exoplanets themselves are not visible. As the lead author Farzana Meru of the University of Warwick explained, "Planets are real, very hard to spot, but planets open a gap in the disk."

What has been compared to a mole leaves a subtle but visible path Where it moves, exoplanets also make paths through protoplanetary disks that astronomers can track, regardless of whether they can observe the exoplanets themselves. This capability is completely new and only possible through the Atacama Large Millimeter / Submillimeter Array (ALMA) telescope in Chile and will help astronomers discover these distant planets.

But because the traces of the exoplanets do not linger For a long time, scientists would normally not be able to fully grasp the entire migration of the exoplanet. And while scientists are aware that planets are capable of having orbits that change in significant ways, so far this has never been directly observed.

However, the new strategy that Meru and her team have developed may possibly be Englisch: bio-pro.de/en/region/stern/magazine/…1/index.html fundamentally changing as scientists will be able to analyze the size of dust in the rings around exoplanets, and Meru notes that scientists can determine dust sizes by observing wavelengths of electromagnetic radiation

Wavelengths of electromagnetic radiation correspond to small dust sizes , and larger wavelengths correspond to larger dust sizes. "

Now scientists studying ALMA data can directly observe dust in these rings to see if it is thick or fine in the other rings." Merus' team has already created a simulation that analyzes how dust particles are released into the rings Migration of exoplanets has been found to accelerate tremendous dust particles near their star, forcing them directly into a broad orbit 19659003] However, dust particles that are large in size become smaller in comparison to small dust particles. slowing down due to ambient gases and grinding, much more easily thrown around, but by studying the dust particles for extended periods of time, Meru believes that scientists will be able to observe two completely separate dust rings around exoplanets migrating on an inner path.

The conclusions of Meru and her research group on The Search for the M igration routes of exoplanets can be found on the preprint server arXiv .
