Star position
The position of a star tells us where it appears in the sky, similar to how we use coordinates like latitude and longitude on Earth. In astronomy, the three main coordinates are right ascension, declination and distance. .. icon More about Star position in StellarGuide

Star mass
Mass of the star DENIS J0630-1840 A is 0.052 solar masses (or 54.5 Jupiter masses.)

The mass of a star is the total amount of matter it contains. It is one of the most important properties of a star, as it determines almost everything about how the star lives, changes, and dies. In astronomy, star mass is usually measured in solar masses (M☉) — where 1 solar mass is equal to the mass of our Sun... icon More about Star mass in StellarGuide

Star size
Radius of the star DENIS J0630-1840 A is not known. Its estimated value based on other similar stars is about 10 % solar radii.

The size of a star refers to its radius — the distance from its center to its surface. Star size is usually measured in solar radii (R☉), where 1 solar radius equals approximately 696,000 kilometers. Depending on their type and life stage, stars can be much smaller or larger than the Sun... icon More about Star size in StellarGuide

Star age
Star DENIS J0630-1840 A is 0.15 billion years old, which is about 0.03 of the Sun's age.

The age of a star tells us how long it has been shining since it formed. Knowing a star’s age helps astronomers understand its life stage, how it has changed over time, and what will happen to it in the future... icon More about Star age in StellarGuide

Lithium burning occurs in brown dwarfs more massive than 52 Jupiters

Astronomers found out long time ago that some brown dwarfs contain lithium a some don't. The difference is in their mass and in a new study scientists led by E. L. Martín present their estimate of the lithium limit. Brown dwarfs over 52 jupiter masses should be able to burn lithium and deplete it rather quickly after their creation.
