On the exoplanet database they have a value which I am not familiar with, can anyone
help me understand what value they are displaying represents?

Luminosity ?
" compared to solar luminosity?

Does LOG mean they performed a logarithm?

see attached picture . Thanks/ bob

Yes---this is the logarithm of the star's luminosity, measured in solar-luminosities.
