White dwarfs: properties - Remaining cores of dead, low mass stars Electron degeneracy pressure supports them against gravity Slowly fade with time Sirius and its hot WD companion White dwarfs with same mass as Sun are about same size as Earth; slowly cooling Typical density 10^6 gram / cubic cm Higher mass white dwarfs are smaller Cannot be more massive than 1.4MSun, the Chandrasekhar limit WDs in binaries: nova, supernova Type I - Mass falls toward white dwarf from binary companion ...

Astronomy Exam #1 Questions With Complete Solutions. What is a star? A star is a large luminous ball of gas that generates heat and light through nuclear fusion. What is a planet? A planet is a moderately large object that orbits a star. It shines by reflected light. Planets may be icy or rocky What is a moon? A moon (or satellite) is an object that orbits the planet. What is an asteroid? An asteroid is a small and ROCKY object that orbits a star. What is a comet? A comet is small a...

During the formation of the Solar System, smaller particles in the solar nebula combined to form planetesimals, some of which provided the building blocks for planets. The majority of planetesimals did not become planets, however, and some of them remain in the Solar System today as debris left over from the time of planet formation. Asteroids are a special class of planetesimals that orbit around the Sun. Study the distribution of known asteroids shown in this figure, and choose all of t...
