Astronomers Discover Unique Planet with Two Suns: Finding from Archives.

According to ТСН: Scientists have discovered a new exoplanet, HD 143811 b, which orbits a binary star system, reminiscent of scenes from 'Star Wars'. This discovery was made possible through the re-analysis of previously collected data.

The exoplanet HD 143811 b is located 446 light-years from Earth. Its sky is illuminated by two stars that orbit around a common center.

Distant but Hot Planet

This planet is a gas giant, primarily composed of hydrogen and helium. Its mass is about six times that of Jupiter. Although the distance to the stars is 80 times greater than the distance from Earth to the Sun, the temperature on its surface reaches 730°C (1346°F).

One orbit of the planet around the binary system takes about 300 Earth years, while the stars orbit each other once every 18 days. Despite the vast distance, this exoplanet is six times closer to its stars than any other exoplanet that has been photographed before.

Discovery from Archived Data

This planet was discovered not during new observations, but by analyzing archival data collected by various telescopes between 2016 and 2019. Two teams of researchers — from the University of Exeter (UK) and Northwestern University (USA) — independently reviewed the archival images.

American scientists, observing the motion of the stars, detected a faint object moving along with the binary system.

'If the planet is linked to the star, it will move together with the star.'

said senior study author Dr. Jason Wang.

British astronomers also confirmed this finding. Lead author Dr. Vito Squicciarini confirmed the discovery in July this year, obtaining new images using a telescope in Chile.

Young Planet and Formation Mysteries

Scientists established that HD 143811 b formed only 13 million years ago.

'In cosmic terms, this is a relatively young body, so it still retains some heat from the time of its formation.'

noted Dr. Wang.

Since only a small number of the 6000 known exoplanets orbit binary star systems, specialists do not yet know how exactly this planet formed. It is believed that stars formed first, and planets appeared later.

Researchers hope that this rare discovery will serve as a 'benchmark' for better understanding the mechanisms of planet formation in similar systems.

'The question is, can we find Earth-like planets in such a system? Perhaps in a few years we will be able to answer these fundamental questions.'

summed up Dr. Squicciarini.

The search for life beyond Earth often focuses on finding a 'second Earth'. However, some scientists suggest expanding the search to worlds that may be even more suitable for life than our planet. The idea of 'super-habitable planets' posits the existence of celestial bodies where the chances of developing biodiversity could be higher than those in our home.

Modern studies of exoplanets open up new possibilities for exploring space and understanding planetary system formation. The discovery of HD 143811 b not only enriches our knowledge of distant worlds but may also help find new paths for confirming life beyond our planet. Scientists continue to work on expanding the boundaries of our knowledge, striving to understand the complexities of planet formation in various stellar systems.
