... The visible power a source emits in all directions is measured in lumens. ... Solid Angle- . ... The solid angle of a light cone is the projected area of the cone divided by the total surface area of the sphere. A solid angle is measured in steradians, where 1 steradian corresponds to the solid angle su btended by a cone of unit slant height and unit projected area. ... Luminous intensity is the flow of luminous energy, or lumens, per steradian. ... This is the rate of flow (lumens) per unit area. ...

This figure shows four snapshots in time as the flame propagates initially subsonically outward reaching a specified density (green) at which point the flame transitions to a detonation. Shown in color is a reaction progress variable describing the burning of nuclear statistical quasi-equilibrium (NSQE) products to nuclear statistical equilibrium (NSE) products. ...

Brown J., Cassinelli J.P., Li Q., Kholtygin A., Ignace R. Optically Thick Clumps - Not the Solution to the Wolf-Rayet Wind Momentum Problem? ... 426 , 323-328 (2004) . The hot star wind momentum problem $\eta=\mdot \varv_{\infty}/(L/c) \gg 1$ is revisited, and it is shown that the conventional belief, that it can be solved by a combination of clumping of the wind and multiple scattering of photons, is not self-consistent for optically thick clumps. ...

... This applet generates an observing list based on an observer's location and time. ... To use this program, enter in your location, and the local times at which you wish to begin and end observing. The date you enter should correspond to the calendar day at the time at which you begin observing. For example, if you wish to observe from 9:37 PM October 23, 2007 until 3:21 AM October 24, 2007, you would enter 21:37 for the starting time, 03:21 for the finish time, and 10/23/2007 for the date. ...
