The same as everywhere else. Every mass has associated energy. Every energy has associated mass.
Possibly this question is about the energy output of stars.
Usually, the more mass a star has the higher its rate of energy output.
What energy is related to the mass and speed of an object
The color of a star is mainly related to the star's surface temperature. This is only remotely related to the star's mass; for example, high-mass stars can either be very hot (blue) or not-so-hot (red), depending on the phase in the star's life.
Kinetic energy is related to an object's mass and its velocity. The formula for kinetic energy is KE = 0.5 * mass * velocity^2. This means that kinetic energy increases with both increasing mass and increasing velocity of an object.
Generally the larger the mass of the star, the more luminous it is.
Mass and gravity are directly connected, and luminosity is closely related to mass.
Kinetic energy is related to the mass and speed of an object. Kinetic energy is the energy an object possesses due to its motion. It is directly proportional to the mass of the object and to the square of its speed.
The energy gained or lost by an object is not directly related to its mass. The energy of an object is typically related to its motion (kinetic energy) or position (potential energy) rather than its mass. However, in certain situations like nuclear reactions, mass-energy equivalence (E=mc^2) can play a role where mass can be converted into energy and vice versa.
it is directly related to the weight or mass of an object
Yes. In a way, energy and mass are closely related; energy HAS mass, mass HAS energy. Energy gets converted into mass routinely in particle accelerators. The kinetic energy from the moving particles gets converted into new particles.
Kinetic energy is related to an object's mass and its velocity. The formula for calculating kinetic energy is KE = 1/2 * (mass) * (velocity)^2.
Because they convert their materials into energy and energy = mass.
A star is a spheroidal plasma converting mass into energy by nuclear fusion.
