I am using the builtin DATEPART function to retrieve month, day and year from a date so I can pass it to the DATENAME function: Now that I have Month, Day, Year values individually, I pass it to my DATENAME to get the Weekname of the date I want: This returns an incorrect Day Name.
Leaving Main Life Sequence. When a massive star has expended all of its core hydrogen, this means that the gravitational forces pushing inward will overcome the fusion forces which had been pushing outward. The outer layers of the star will then compact inwards.
The main fuel of stars is the most fundamental element in the universe -- hydrogen. Most stars spend most of their lives fusing hydrogen into helium. Only later in life do the â¦ y fuse helium into heavier elements, and continue to fuse lighter nuclei into the elements up through iron.
