What did Subrahmanyan Chandrasekhar discover?

Subrahmanyan Chandrasekhar (1910 – 1995)

Subrahmanyan Chandrasekhar was born on October 10, 1910 in Lahore. His father “Subramania Iyer” was an officer in the Financial Audit Department at the time. Mother “Sita” has been the head of the family and is proud to have translated many English books into Tamil. Chandra Sekhar had 4 brothers and 6 sisters. Chandrasekhar is the son of Nobel Laureate C. V. Raman sister.

Subrahmanyan Chandrasekhar was educated by his parents and private tutor until he was 12 years old. After his father moved to Chennai in 1918, his family moved to Chennai permanently. After completing his schooling at the Hindu High School in Chennai, he started graduating from the State College. He graduated in Physics (BSc Hons) in June 1930. He received a scholarship from the Government of India based on his educational qualifications and joined the University of Cambridge in the United Kingdom. There he received his doctorate from Chandrasekhar Cambridge University in 1933 as a research student under the supervision of Professor Fowler. He then received research assistance at the prestigious Trinity College and worked there for three years. In the meantime, at the invitation of Dr. Har Shapley in 1936, Har worked briefly at the University. Then Dr. Otto Struve and Robert Hunsins invited Chandrasekhar to join the University of Chicago as a researcher. He joined the University of Chicago in January 1937 and continued his research there until his death.

Subrahmanyan Chandrasekhar may have come to the surface and stared at the sky in solitude, while lying on the ship in the 1930s. Then he wondered what the star would be like after burning all his nuclear fuel. As a result of his continued thinking and research, Chandrasekhar formulated a mathematical theory of death, which he confirmed in several ways and submitted to the Royal Astronomical Society in 1935. Ain’s discovery was ridiculed by the then famous astronomers. Although this setback made him very tired for now, he was convinced that his discovery was correct. After that while working at the University of Chicago. He published his findings as a book entitled An Introduction to the Stellar Structure of the Stars and put an end to it.

The series of motivations of his research quest led him to engage in another new research. It’s about “the way stars spread in star clusters.” It is noteworthy that Dr. Chandrasekhar was thus involved in six different researches and made rare discoveries about them to the scientific world. This is what he mentioned when asked to comment on how he had thus researched each other on different topics.

My approach to the milk of science is similar to the approach of a sculptor. The sculptor does not keep his chisel on his finished sculpture. He will start carving another sculpture. I also have a habit of going from one topic to another after finishing. Chandrasekhar’s process became known among scientists as the “Chandrasekhar Act“.

Nobel Prize

When Dr. Chandrasekhar was nominated for the Nobel Prize, he was surprised to find that at the age of 25 he was awarded the prize for “facts about the structure of the galaxy – then ridiculous” that he had discovered. The book, published in 1939, illustrates the importance of his discovery as a key guide for students studying astronomy at universities around the world today.

When Chandrasekhar’s name was nominated for the Nobel Prize, the selectors were said to be in a dilemma. This is because the recommendation committee had made its recommendation citing seven important findings. The selection committee considered them all to be eligible for the prize. They felt that the value of the Nobel Prize had been increased by awarding it to Chandrasekhar.

Among Dr. Chandrasekhar’s many commendable studies on astronomy, we find some details about the discovery that won him the Nobel Prize. His discovery is called the “Chandra Sekar Limit“.

It is about the birth and death of stars, i.e. their origin and destruction. Chandrasekhar’s discovery that a star is formed in a very large cloud of gas and particles called a nebula. (gravity) When such large clouds are pulled they are compressed. The result is heat. A portion of this heat propagates as heat rays in different directions. Thus further compression of the particles (mass). As this phenomenon continues its internal temperature rises to over one million degrees Celsius At such high temperatures the atoms of the hydrogen gas begin to intertwine and turn into helium gas. During this event they emit a lot of heat and light which is the birth of the star.

We know that every star is like the sun. They look so small to our eyes because they are so far away. Stars vary greatly in size, density, and temperature, and are many times larger or smaller than the Sun. The lifespan of a star depends on the nitrogen fuel it contains. A star dies when it runs out of hydrogen.

Black hole

A very heavy star – many times heavier than the Sun – crashes due to its gravitational pull, and eventually even light becomes inaccessible. This is called a black hole.

Super Nova

Then that star starts to shrink. In its constant constriction it is called the dwarf star. For example, only the size of a small goliath shell weighs several tons. A star that weighs more than the Sun is stunning and swells many times its size and then suddenly explodes. This is called a “super nova

According to Chandrasekar’s Limit, a star can only become a “dwarf star” if it weighs about 11/2 times the weight of the Sun. If they weigh more than this, they swell and explode into supernovae. Chandrasekhar calculated this by his mathematical equations. This is a fact that has been proven by studying many dwarf stars.
