A protostellar cloud will continue to collapse as long as the gravitational binding energy can be eliminated. This excess energy is primarily lost through radiation. However, the collapsing cloud will eventually become opaque to its own radiation, and the energy must be removed through some other means. The dust within the cloud becomes heated to temperatures of 60–100 K, and thes… WebStar formation is the process by which dense regions within molecular clouds in interstellar space, ...

Stars with less than 0.5 ... WebThose stars have [Fe/H] values no larger than −1.5 and sometimes as low as −3.5. Called metallicity, [Fe/H] indicates the overall abundance of elements beyond hydrogen and helium, up to and including iron. Also, r-I and r-II stars presumably formed early in cosmic history, whereas the solar system is a relatively youthful 4.6 billion years old. fishman bass blender issues

Unlike the elements before it, iron releases no energy when fused. This is because iron has the most stable nucleus of all the elements. Elements lighter than iron generally emit energy if fused, since they move from a less stable nuclear structure to a more stable one.
