Here, we generalize Vaidya’s metric to a star that is rotating and radiating. Although, there is a famous Kerr solution [2] for a rotating star, but here is a simple solution for a rotating star which may be termed as a zero approximate version of the Kerr solution. Results are discussed. 11 30 2021 1 7 https://creativecommons.org/licenses/by-nc/4.0/ 10.55672/hij2021pp,1-7 https://hscience.org/index.php/hij/article/view/7 https://hscience.org/index.php/hij/article/download/7/12 https://hscience.org/index.php/hij/article/download/7/12
