This will determine if the TDE actually involves the destruction of a Pop III star. "Since these stars are only made up of hydrogen and helium, we will not see any metal lines in the spectrum of objects, whereas, in the spectra of TDEs from regular stars, we can see various metal ...
[02:39.24]and from telescopes in Hawaii and in the Canary Islands. [02:44.20]Stars are mostly made up of hydrogen, [02:46.84]with smaller amounts of helium and other elements. [02:51.12]In this system, the larger ...
1. What gases are stars mostly made of? Hydrogen and helium Oxygen and helium Oxygen and hydrogen Holmium and helium 2. What is the method called that a star uses to burn hydrogen, turning it into helium? Nuclear fusion Atomic bonding Nuclear fission Nuclear decay Create your acc...
Stars are predominantly composed of hydrogen (71%) and helium (27%) gases, with traces of heavier elements such as oxygen, carbon, neon and iron. Some smaller stars have lived since the earliest era of the universe, showing no signs of dying after more than 13 billion years of existence....
A star is a large celestial body that is composed of gas and emits light. Stars are made mostly of hydrogen and helium. They also contain other elements in small amounts. Stars emit light and vary in brightness. Unit 1 Lesson 2 Stars ...
Cecilia Payne-Gaposchkin discovered that stars are primarily made of hydrogen and helium, at a time when astronomers thought that the Sun and the Earth had no significant elemental differences. She proposed that hydrogen wasn’t only more common, but that it wasa milliontimes more common. ...
An example of the Moon’s influence is the way it affects ocean tides. The gravitational pull of the Moon causes high and low tides on Earth. The Stars: The Twinkling Giants Stars are massive celestial bodies made up of gases, predominantly hydrogen and helium, that generate energy through ...
What are small stars called? Answer and Explanation:1 Stars, like the Sun in our solar system, are simply balls of blazing hot gases. They are mostly made up of helium and hydrogen. The largest stars in... Learn more about this topic: ...
The sun – made up mainly of hydrogen and helium – is an average-sized star that formed more than 4.5 billion years ago. It stretches about 1.4 million kilometers across and has a surface temperature of 5,500 degrees Celsius. 太阳形成于45亿年前主要由氢和氦组成,其大小处于恒星界的平均水平...
So, if Pop II needed more metals than the Big Bang could provide, they must have made use of the remnants of Pop III stars. Pop III stars are believed to be made almost entirely of hydrogen and helium—very low metallicity. They would have been truly massive, and likely would not have...
