The universe, whose size we do not yet have and probably will not have for a long time, contains many interesting things. We still have a long way to go to explore the universe, which is home to millions of galaxies, but many societies throughout history have conducted various investigations into this. We’ll also show you what you can see today when you look up at the sky. Sirius, the brightest star We reviewed the studies.
It is estimated that this star, which is quite large compared to the Sun, was formed about 200 to 300 million years ago. We can see it so clearly because of its proximity to Earth. SiriusIt has been the subject of many books, films and TV series, even today. If you remember after what we said What is the star SiriusIf you have any questions like: how far is it from Earth, how big is it, then you can start reading our content without wasting time.
Also called ‘Alpha Canis Majoris’ Sirius, belongs to A1 as a spectral type. Stars like this fall between A0 and A1 in temperature and color, while Sirius’ other spectral features are more consistent with those of A1. So even though it looks like a single star at first glance, Sirius is actually a star. Sirius A And from Sirius B A double star has been formed.
Sirius A is considered the primary star and Sirius B is considered the companion star. Sirius B is a white dwarf star of spectral type DA2. With an apparent magnitude of -1.46, Sirius is about 100 degrees above Canopus, the second brightest star in the night sky. twice as much It’s so bright.
Sirius AIt is a very large and massive star compared to the Sun. It is estimated that Sirius, which has a mass about twice that of the Sun, will have a shorter life than the Sun. The biggest reason for this is that they burn faster because they have a higher mass and temperature.
Researchers, from Sirius A predicts that its future in stellar evolution will end with its collapse into a white dwarf. These estimates indicate that Sirius is still in the middle of its life and has not yet entered the final phase of its evolution.
In ancient Egypt’So this’ Sirius, known as Sirius, was very important to the Egyptians. The Egyptian people, who had fertile agricultural lands, lived according to the birth of the Sirius star. of the Nile River He tried to predict the annual flood. Because the flooding of the Nile produced mud and water that was vital for agriculture. Therefore, the birth of this bright star signified fertility among the ancient Egyptians.
large canis Located in the constellation Canis Major Sirius, To Earth 8.6 light years It is one of the closest stars we can observe with its distance. The brightness of stars depends on their distance from Earth, so the fact that Sirius is so close to Earth is one of the main factors that make it appear so bright.
However Sirius A, It is a very bright star regardless of distance. Sun approximately. 25 times Sirius A has an enormous surface temperature and high energy due to its brightness.
Sirius According to recent studies of the star system Formed 200 to 300 million years ago It’s estimated. This prediction was made based on the evolutionary process that Sirius A has undergone to this day. As we mentioned above, the age of this star, which belongs to spectral type A1, can be easily estimated from its life cycle.
Generally Sirius and other stars with similar properties have a lifetime of approx 1 billion years It can amount to . This shows that Sirius A still has many years ahead of it. It is estimated that Sirius B is a main sequence star and turned into a white dwarf star about 120 to 150 million years ago.
Siriusin Harry Potter, one of the most famous series in world film history. Sirius Black He gives his character his name. Its location in the Canis Major constellation is related to Sirius Black’s ability to transform into a dog as an Animagus. Sirius Black The dog form is depicted as a large, black dog, which details the origin of the name Sirius and represents the character’s characteristics such as courage and protection.
It can be mistaken for a UFO by many people because it has a very bright structure and experiences significant flicker and color change when observed depending on atmospheric conditions. Fluctuations in the atmosphere cause the light emitted by stars to be refracted by different layers of air as it reaches Earth. from Sirius The light is also affected by these fluctuations in the atmosphere and flickers, giving it a misleading appearance.
Sirius, It is the first star whose speed was measured. Famous German astronomer who lived in the mid-19th century Friedrich Wilhelm Besselmanaged to measure the speed of this star. In 1838, Wilhelm Bessel discovered small, regular movements of Sirius and similar stars, indicating that they moved under the gravitational influence of their invisible companions surrounding their stars. All these observations made during those years, Sirius’ speed It also provided the first clues about the existence of Sirius B, whose existence was unknown until then.
