WHAT DOES SUBSTELLAR MEAN IN ENGLISH?

substellar

Substellar object

A substellar object, sometimes called a substar, is an astronomical object whose mass is smaller than the smallest mass, approximately 0.08 solar masses, at which a star can sustain hydrogen fusion. This definition includes brown dwarfs, former stars similar to EF Eridani B, and can also include objects of planetary mass, regardless of their formation mechanism and whether or not they are associated with a primary star. Assuming that a substellar object has a composition similar to the Sun's and at least the mass of Jupiter, its radius will be comparable to that of Jupiter. This is because the center of such a substellar object just below the hydrogen-burning limit is quite degenerate, with a density of ≈103 g/cm3, but this degeneracy lessens with decreasing mass until, at the mass of Jupiter, a substellar object has a central density less than 10 g/cm3. The density decrease balances the mass decrease, keeping the radius approximately constant.

Definition of substellar in the English dictionary

The definition of substellar in the dictionary is an astronomical object with a mass smaller than the mass needed by stars for nuclear fusion.
