Tiny Planets Discovered Orbiting One of Our Nearest Stars!

Washington D.C., [USA], March 12 (ANI): Astronomers have uncovered fresh evidence indicating the presence of not one but four small planets orbiting Barnard’s Star. Star the star system second closest to Earth

The four planets, each roughly 20 to 30 percent the mass of Earth, orbit so closely to their parent star that they complete a full revolution in just days. This proximity likely makes them too warm to support life; however, this discovery sets a new standard for identifying smaller celestial bodies around neighboring stars.

It's truly an exhilarating discovery -- Barnard's Star Star Even though it's our cosmic neighbor, we still have much to learn about it," stated Ritvik Basant, a Ph.D student at the University of Chicago and lead author of the study. "This marks a significant advancement thanks to the enhanced accuracy of these newer tools compared to those from earlier times.

This discovery lends credibility to a November study conducted by another group utilizing a separate telescope, which provided substantial evidence of a single planet orbiting Barnard’s Star. Star and hints at others.

The latest research, involving experts from the Gemini Observatory/National Science Foundation NOIRLab, Heidelberg University, and the University of Amsterdam, will be released on March 11 in The Astrophysical Journal Letters.

For a hundred years, astronomers have been researching Barnard's Star. Star In the hope of discovering planets orbiting it, this celestial body was first identified by E.E. Barnard at Yerkes Observatory back in 1916. It stands as our closest neighbor possessing a single-star structure similar to ours. (It’s worth noting that the star system closest to Earth, Proxima Centauri, consists of three stars revolving around each other, altering the patterns of planetary creation and orbital paths.)

Barnard's Star There exists a category known as an M dwarf star, which we have learned are incredibly abundant throughout the cosmos. Consequently, researchers are eager to discover more about the types of planets these stars harbor.

The problem is that distant exoplanets are incredibly small compared to the brightness of their stars, making them nearly impossible to observe directly with even our strongest telescopes. As a result, researchers have needed to adopt innovative methods to detect these elusive worlds.

An initiative like this was spearheaded by University of Chicago Professor Jacob Bean. His group developed and set up a device named MAROON-X, which is mounted on the Gemini telescope atop a mountain in Hawaii. This equipment is specially crafted to hunt down far-off exoplanets.

Since stars outshine their planets significantly, it becomes simpler to observe the impact that planets exert on their stars — akin to gauging the breeze by observing the movement of a flag.

MAROON-X searches for such an effect where the gravitational pull from each planet causes slight movements in the star’s position, making it appear as though the star is oscillating back and forth. By measuring changes in the starlight with incredible precision, MAROON-X can detect these subtle motions and determine both the quantity and mass of the planets responsible for this phenomenon. (ANI)
