Web1 hour ago · Actor Zayed Khan spoke about arguably the biggest hit of his career, the 2004 film Main Hoon Na, in which he starred alongside Shah Rukh Khan and Amrita Rao. The film was directed by Farah Khan, who was making her debut, and is still remembered for a hit one-shot song sequence, ‘Chale Jaise Hawayein’. WebDuring the main sequence, the star is supported by the fusion of hydrogen into helium. Eventually, the hydrogen runs out at the centre, so hydrogen fusion is no longer possible there. Why doesn't it start fusing helium into carbon right away? That's because the core isn't hot or dense enough yet.

WebThe way a star dies depends on how much matter it contains—its mass. As the hydrogen runs out, a star with a similar mass to our sun will expand and become a red giant. When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant. WebSep 17, 2024 · The star has started evolving into what is known as a subgiant star, representing an intermediate phase between the main sequence and the red giant stage. … WebFrom Main-Sequence Star to Red Giant Eventually, all the hydrogen in a star’s core, where it is hot enough for fusion reactions, is used up. The core then contains only helium, “contaminated” by whatever small percentage of heavier elements the star had to begin with. how does phentaslim work

A red giant star is formed when a star, like our Sun, burns all of … A star becomes a giant after all the hydrogen available for fusion at its core has been depleted and, as a result, leaves the main sequence. The behaviour of a post-main-sequence star depends largely on its mass.
