The Vaidya-metric of Dr Vaidya is very widely used today in astrophysics. of the articles published in science magazines such as General Relativity and Gravitation, Quantum Theory and Gravitation, Physical Review, Physics Today, nearly 20 articles published every year, widely use Vaidya-metric.
Showing his gratitude to Dr V. V. Narlikar, Dr Vaidya writes about his first research paper : "Professor Narlikar wrote only my name as the author of the article that we wrote to give publicity to this solution. Generally, the authorship of an article is attributed to the teacher who suggested the problem and the name of the student is mentioned as the co-author but Narlikar did not do so because the basic idea of finding a solution had occurred to me. He, therefore, gave all the credit for finding the solution only to me. Today when I think of this I realized that Narlikar very well knew the full importance of the solution that we had found. If as the author of the article he had mentioned his name also along with my name, the solution would have been famous by his name and since I was very young at that time to know all this, he could have very easily attributed to his name the solution which is known today as "Vaidya's solution". But he stuck to academic decorum and decided that since the main idea of the solution was Vaidya's, the solution should be attributed to Vaidya's name. This is academic honesty."
In 1963 A.D. a scientist named Roy P. Kerr found the solution to the problem of determining the field of external gravitational force of 'Black Holes', non-luminous stars moving round. Later on, several scientists made attempts to find a solution to the problem of determining the field of gravitational force of luminous stars moving round but they did not succeed.
Dr Vaidya had already solved the problem of determining gravitational force of luminous stars by taking into consideration the light / energy emitted by them. In 1973 A.D. Dr Vaidya and Dr Liladhar K. Patel, one of his students, found out an original method of determining the gravitational force of rotating stars. This method is known as 'Radiation Kerr Metric'. This is another important research of Dr Vaidya in the field of relativity and gravitational force.
Very many students have done research work in the guidance of Dr Vaidya. Till today he has been directly or indirectly associated with world - famous science institutes of India and especially of Gujarat. Even today, the scientists of 'Physical Research Laboratory'(PRL).'
