Answer: If we observe a low-mass helium white dwarf then we can conclude that low mass helium composed of mainly helium which is a relatively cool white dwarf having high density which will cool and fade over the time and having stellar remnant.

Step-by-step explanation:

It is a stellar remnant: The fact that you are observing a white dwarf indicates that it is the remnant of a star that has completed its main sequence evolution.

It has exhausted nuclear fusion: White dwarfs are no longer capable of generating energy through nuclear fusion.

It is composed mainly of helium: The term "helium white dwarf" suggests that the star's core is predominantly composed of helium

It is a relatively cool white dwarf: The mass of the white dwarf affects its temperature and luminosity.

It has a high density: White dwarfs are incredibly dense objects.

It will cool and fade over time: As they cool, their luminosity decreases, and they become fainter and more difficult to observe.
