Down: 1) the nuclear fusion process that combines three helium nuclei (alpha particles) to make one carbon nucleus 2) radiation emitted when high-speed electrons move through a magnetic field3) an expanding shell of gas ejected from a star during the latter stages of its evolution4) the volume of space a star controls gravitationally within a binary system5) points of gravitational stability in the orbital plane of a binary star system or of a planet and its moon6) the explosive ignition of helium fusion that takes place in a some giant stars8) a cluster of 100 to 1000 stars with an open, transparent appearance, usually relatively young and located in the disk of the galaxy. the stars are not tightly grouped9) the explosion of a star, thought to be caused by the transfer of matter to a white dwarf10) a measure of the tendency of a rotating body to continue rotating. mathematically, the product of mass, velocity, and radius11) the explosion of a massive star that develops an iron core and collapses after it has lost its outer layers of hydrogen13) a supernova explosion in which the spectrum contains no hydrogen lines. 14) the dumbbell-shaped surface that encloses the Roche lobes around a close binary star15) a moon with an orbit that has small eccentricity and low inclination to the equator of its parent planet and is prograde. regular moons are thought to have formed with their respective planets rather than having been captured Across: 7) a supernova explosion caused by the collapse of a massive star12) extremely high-density matter in which pressure no longer depends on temperature due to quantum mechanical effects16) in the HR diagram, stars fusing helium in a shell and evolving back toward the red giant region17) the point in an HR diagram at which a cluster's star turns off the main sequence and move toward the red-giant region, revealing the approximate age of the cluster 18) the explosion of a star, thought to be caused by the transfer of matter to a white dwarf19) a supernova explosion caused by the collapse of a white dwarf 20) the point of gravitational equilibrium between two orbiting stars through which matter can flow from one star to the other 21) from Latin, meaning "new;" a sudden brightening of a star making it appear as a new star in the sky; believed to be associated with eruptions on white dwarfs in binary systems22) the maximum mass of a white dwarf, about 1.4 solar masses. a white dwarf of greater mass cannot support itself and will collapse23) the whirling disk of gas that forms around a compact object such as a white dwarf, neutron star, or black hole as matter is drawn in24) a star cluster containing 100k to 1 million stars in a sphere around 75ly in a diameter that is generally old, metal-poor, and found in the spherical component of a galaxy25) the expanding shell of gas marking the site of a supernova explosion
