At low luminosities, the objects to be unified are Seyfert galaxies.

Stars much less massive than the Sun have very long main-sequence lifetimes, but they also have low luminosities.

They also have relatively high space velocity and low luminosities for stars of their stellar classification.

It is similar in mass to the Sun, although it is cooler and has a lower luminosity.

Both stars are considered unusual because they have a lower luminosity than is normal for main sequence stars of their age and surface temperature.

It also has the lowest spindown luminosity of any pulsar at about 3x10 watts.

It likes the climate that have high humidity and low luminosity.

VB 10 has an extremely low luminosity with an absolute magnitude of nearly 19, making it very difficult to see.

Wolf 359 has a very low luminosity, emitting about 0.1% of the Sun's energy.

Lower mass stars have lower luminosities and are seen as yellow giants.
