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 ...

Star light, star bright, last stars we'll see … ever
British Journal of Nursing, 2005I've been bombarded this past week with press releases from everyone under the sun who has a comment on the Healthcare Commission's star ratings. Not that I mind so much; those press releases have given me the idea for this issue's editorial.

Magnetic Resonance in Medicine, 2018
PurposeTo introduce a novel MR pulse sequence, termed Looping Star, for fast, robust, and yet quiet, 3D radial multi‐gradient echo T2* MR imaging.MethodsThe Looping Star pulse sequence is based on the 3D radial Rotating Ultra‐Fast Imaging Sequence (RUFIS) extended by a time‐multiplexed gradient‐refocusing mechanism.

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

Star Products, Star Exponentials, and Star Functions
2018We give a brief review on non-formal star products and star exponentials and star functions (Omori et al., Deformation of expressions for elements of an algebra, in Symplectic, Poisson, and Noncommutative Geometry. Mathematical Sciences Research Institute Publications, vol. 62 (Cambridge University Press, Cambridge, 2014), pp.

Science, 2016
Light Pollution More than 80% of the world's population lives under skies polluted by the luminescent glow of artificial lights. Falchi et al. present an atlas that shows how increasing light pollution has obscured our night skies, hiding celestial attractions like the Milky Way from more than one-third of the planet's population.

1996
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 ...
