I just wanted to check to make sure I put these in the right order

steps of a low mass star

a clump forms in a giant molecular cloud. then a prostar forms

hydrogen fusion begins

the star moves onto the red giant branch, then a helium flash occurs

the star moves onto the horizontal branch

the star moves onto the asymptotic branch, then the star sheds mass producing a nebula.

the white dwarf cools

To determine the correct order of these steps for a low mass star, we can follow the life cycle of such a star. Here's the correct sequence:

1. Clump Formation: A clump forms in a giant molecular cloud, which is a dense region of interstellar gas and dust.

2. Protostar Formation: Gravity causes the clump to collapse, forming a protostar. At this stage, the protostar is not yet undergoing nuclear fusion.

3. Hydrogen Fusion: When the core temperature of the protostar reaches about 10 million Kelvin, hydrogen fusion begins. The pressure and temperature at the core of the star become high enough to sustain nuclear reactions, converting hydrogen into helium.

4. Red Giant Branch: As the star consumes its hydrogen fuel in the core, it starts to expand and becomes a red giant. The star's outer layers expand outward while the core contracts.

5. Helium Flash: In the red giant phase, the core temperature rises and eventually becomes hot enough for helium fusion to occur. This sudden onset of helium fusion is known as the helium flash.

6. Horizontal Branch: After the helium flash, the star stabilizes and moves onto the horizontal branch, where it burns helium in its core.

7. Asymptotic Branch and Mass Shedding: As the helium in the core is depleted, the star further expands and enters the asymptotic branch. During this phase, the star experiences episodes of mass shedding, resulting in the formation of a nebula.

8. White Dwarf Cooling: Once the star has shed most of its outer layers, what remains is a hot, dense core known as a white dwarf. Over time, the white dwarf cools and fades away.

So, the correct order of the steps for a low mass star is: Clump formation, Protostar formation, Hydrogen fusion, Red giant branch, Helium flash, Horizontal branch, Asymptotic branch and mass shedding, and White dwarf cooling.
