Astronomers have modeled a nearby star to resemble the early Sun

The star Kappa 1 Ceti is one of the analogues of the Sun. It is located about 30 light years from us - in space

In terms of this, she can be called a «neighbor down the street». According to preliminary estimates, it is between 600 million and 750 million years old. By the way, our Sun was approximately the same age when life began on Earth.

Meng Jin, a heliophysicist at the InstituteSETI and co-author of the study, Kappa 1 Ceti has a mass and surface temperature similar to the Sun. All these factors make the star's "twin" an important object for research.

We analyze a young star who in the futurewill become the same as the sun. This means that we can study the past of the Sun, and this is simply incredible. Obtaining data on the young Sun will answer many questions related to the formation of the solar system.

So, scientists adapted the existing modelSun to predict some of the most important but difficult to measure characteristics of Kappa 1 Ceti. The model is based on data input from various space missions, including NASA/ESA's Hubble Space Telescope, NASA's Transiting Exoplanet Survey Satellite and NICER missions, and ESA's XMM-Newton.

The basis for the new Kappa 1 Ceti ismodel of the Sun with Alfvén waves. It works by inputting known information about a star, including its magnetic field and ultraviolet radiation lines, to predict stellar wind activity. The model has already been tested on the Sun to make sure that the scientists' predictions are correct.

Astronomers have published the study in The Astrophysical Journal.
