The Jeddah Astronomical Society has confirmed that a new study may indicate the presence of planetary debris containing moon-sized objects. Planet The possibility of a rock within a habitable zone around a dead star.

The star is a white dwarf called WD1054-226, a cold remnant of a star that has exhausted all fuel, and if that planet were confirmed outside our solar system, it would be a breakthrough in white dwarf astronomy. The planet has previously been found orbiting a white dwarf, but it is a gas giant planet similar to Jupiter, not near the habitable zone, “the area defined as the perfect groove of liquid water on the surface of a rocky planet”.

In general, astronomers are not easy to confirm the existence of a planet with current technology because it is done by comparing computer models with more observation of the star and the debris around it.

The star WD1054–226, 117 light-years from Earth, is close enough to be seen directly by many telescopes.

Researchers have discovered that a planet could orbit a white dwarf due to the apparent tips of starlight detected by a 3.5-meter European Southern Observatory at La Silla Laboratory in Chile.

Data show that the decline in brightness of WD1054–226 corresponds to 65 “equal intervals” of planetary debris clouds orbiting the star every 25 hours. The uniform distribution of debris in space suggests that a rocky planet (about the size of Earth) could hold everything in place.

White dwarfs are important because they provide an overview of what will happen to our solar system when the sun leaves hydrogen in about five billion years. Before collapsing into a white dwarf, the stars pass through what is known as the red giant galaxy, where they expand 100 to 1,000 times and burn the planets closest to them.

When the sun becomes a red giant, life on Earth will no longer be possible, and will temporarily shrink back to include only the most intimate surroundings of the cool white dwarf, moving toward the outer part of our solar system.

A possible orbiter around the star WD1054–26 is about 28 times closer to the Sun than Mercury, orbiting 2.5 million km from the star and fitting in a habitable zone.

What’s even more interesting is that after the red giant collapsed into the white dwarf, all the debris could possibly have formed a planet or somehow come to the region because the object was so close that it was swallowed by the red giant.

The planet around the white dwarf is expected to be swept away by the giant star phase of its life, so any planet could have water and thereby be the latest evolution for at least two billion years, including at least one billion years. In the future.
