Astronomy Unit 7 Exam - Questions & Answers Accretion is a gradual growth of a body by the accumulation of other, smaller bodies. White dwarf is a star with sufficiently high surface temperature that it glows white. Chandrasekhar limit is the maximum possible mass of a white dwarf. Process of Science: Stars Leaving the Main Sequence Part A: A star is in hydrostatic equilibrium when the outward push of pressure due to core burning is exactly in balance with the inward pull of gravity. When the h...
