How does a 1.2-solar-mass white dwarf compare to a 1.0 -solar-mass white dwarf?

Answer 1

The sun is still converting hydrogen into helium and on up the Periodic Table. Basically the sun is in static equillibrium between expansion and contraction due to gravity. When a sun reaches the white dward stage it no longer has the gravitational force to undergo the fusion of hydrogen into helium ect

Answer 2

The 1.0 dwarf is brighter. the lower the number the brighter it is.

One thing that can be guaranteed is that the 1.2-solar-mass object has, by comparison and gravitational behavior, 20% more mass than the 1.0-solar-mass one.

Answer 3

A 1.2-solar-mass white dwarf would be more massive and therefore have a higher gravitational pull compared to a 1.0-solar-mass white dwarf. This can lead to differences in the internal pressure and temperature, affecting its evolution and eventual fate. Generally, the higher-mass white dwarf would cool more slowly and take longer to reach the endpoint of its evolution.

Answer 4

A white dwarf is a one solar mass star which has finished fusing hydrogen then helium in its core and is therefore no longer producing energy, and has shrunk in size and is now cooling.

Answer 5

it has a smaller radius
