Star mass
The mass of the star LSPM J1931+1906 A is unknown. Based on its other characteristics, it is estimated to be about 20 % of the Sun's mass.

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 LSPM J1931+1906 A is not known. Its estimated value based on other similar stars is about 20 % 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 temperature
Surface temperature of LSPM J1931+1906 A is estimated to be 3221 K, which is 55 % of the temperature on the surface of the Sun.

The temperature of a star refers to the temperature at its surface, also called the photosphere. It is measured in kelvins (K), the standard unit for temperature in astronomy. A star’s temperature tells us a lot about its physical properties and where it stands in its evolutionary stage... icon More about Star temperature in StellarGuide

A planet’s escaping helium, a star’s hidden infrared rhythms, and a possible distant world in the WISPIT 2 system reveal how much we can learn by watching light across the spectrum. New observations also trace the changing radio and X-ray activity of young V1298 Tauri, while detailed models map cloudy and clear regions across the hot Jupiter WASP-43 b.
