Star formation and the ages of stars [PDF]
EAS Publications Series, 2014 In this contribution we illustrate how the knowledge of the ages of stars is important to constrain star formation processes. We focus on two specific cases: star formation around the supermassive black hole at the center of the Galaxy and triggered star formation on the borders of Hii regions.

Compact stars: Neutron stars or quark stars or hybrid stars?
Physics Reports, 1994Abstract Using results from energy calculations of neutron matter, we construct various neutron star equations of state. From these equations of state, together with the Tolman-Oppenheimer-Volkoff equations, we calculate quantities such as pressure, mass density, mass energy density, total mass, radius, and moment of inertia for neutron stars ...

Bulletin of the Atomic Scientists, 1993
The island of Kuai, home to the Pacific Missile Range Facility, is preparing for the first of a series of Star Wars rocket launches expected to begin early this year. The Strategic Defense Initiative plans 40 launches of the Stategic Target System (STARS) over a 10-year period. The focus of the tests appears to be weapons and sensors designed to combat

Astronomy and Astrophysics were first treated in volume III of the 6th edition of Landolt-Bornstein in 1952, then in volumes VI/1 and VI/2 of the New Series, 1965 and 1981/82 respectively. The present volume VI/3 is a further supplementation of volume VI/1.

Be Stars, Shell Stars, and Of Stars
1966The fact that some stars rotate rapidly was discovered by Schlesinger (1909, 1913) who found a small distortion of the radial-velocity curve during the ingress to and egress from eclipse of the principle components of δ Librae and of λ Tauri. This he interpreted as a rotational effect. This discovery was followed up and consolidated by studies of other

The stars do not appear to be of equal brightness. About 125 BC, Hipparchus made the first classification of stars according to their brightnesses. His predecessor, Aristarchus (310–230 BC), had proved that the Sun, Moon and planets are at varying distances from the Earth, and that they do not move equally far from the Earth against a crystal sphere ...
