Scientists from Japan’s National Institute for Astronomical Research have discovered one of the rarest stars in the Milky Way galaxy. The star, which has been named J1124+4535, is about 9,000 light-years from Earth and has a mass 1.5 times that of the Sun. But what makes this star so rare, and why is it so important to science?
One of the features of the star J1124+4535 is its low metallicity. Metallicity is the ratio of the mass of all elements except hydrogen and helium to the total mass of the star. In this case, the star has a metallicity that is only 1/10 that of the Sun. This means that the star was formed a very long time ago, when there were very few heavy elements in the galaxy.
Also, the star J1124 + 4535 has a very low rotation rate, which makes it even rarer. This means that the star was formed very slowly and was probably part of the first generations of stars in the galaxy.
Scientists hope that studying the star J1124 + 4535 will help them better understand what conditions were necessary for the formation of the first stars in the galaxy. It may also help scientists better understand how the Milky Way galaxy evolved and how it became what we see today.
It is interesting to note that J1124 + 4535 was discovered through the use of spectroscopy. This method uses the light that a star emits to determine its chemical composition and other characteristics. This method is one of the most effective ways to study stars and galaxies.
Overall, the discovery of the star J1124 + 4535 is an important step in understanding the origin and evolution of the Milky Way galaxy. Scientists continue to study this star and hope that it will help them uncover even more secrets of our galaxy.
