Star mass
Mass of the star HD 63754 A is 1.41 solar 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 HD 63754 A is 1.891 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 HD 63754 A is 6153 K, which is 106 % 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

The early architecture of planetary systems may be set at birth: a study of Sun-like stars found similar rates of star-planet misalignment across different stages of development. Other findings trace how water and carbon dioxide ice fade around young stars, why white-dwarf debris resists breaking into tiny pieces, and why a reported planet around Gliese 48 remains unconfirmed.
