Models. A stellar evolutionary model is a mathematical model that can be used to compute the evolutionary phases of a star from its formation until it becomes a remnant. The mass and chemical composition of the star are used as the inputs, and the luminosity and surface temperature are the only constraints.
Stellar classification. In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with spectral lines.
A vertical service code ( VSC) is a sequence of digits and the signals star (*) and pound/hash (#) dialed on a telephone keypad or rotary dial to access certain telephone service features. [1] Some vertical service codes require dialing of a telephone number after the code sequence. On a touch tone telephone, the codes are usually initiated ...
A* search algorithm. A* (pronounced "A-star") is a graph traversal and pathfinding algorithm, which is used in many fields of computer science due to its completeness, optimality, and optimal efficiency. [1] Given a weighted graph, a source node and a goal node, the algorithm finds the shortest path (with respect to the given weights) from ...
For example, in the NYPD system, Code 10-13 means "Officer needs help," whereas in the APCO system "Officer needs help" is Code 10-33. The New Zealand reality television show Ten 7 Aotearoa (formerly Police Ten 7 ) takes its name from the New Zealand Police ten-code 10-7, which means "Unit has arrived at job".
An A-type main-sequence star (A V) or A dwarf star is a main-sequence ( hydrogen burning) star of spectral type A and luminosity class V (five). These stars have spectra defined by strong hydrogen Balmer absorption lines. [1] They measure between 1.4 and 2.1 solar masses ( M☉) and have surface temperatures between 7,600 and 10,000 K, meaning ...
The VO will start the power to the cooling in the morgue (presuming it is not already in use) as a precaution. Charlie, Charlie, Charlie is the code for a security threat aboard Royal Caribbean ships and the code for upcoming helicopter winch operations aboard c-bed accommodation vessels. Code blue usually means a medical emergency.
Alt code. On personal computers with numeric keypads that use Microsoft operating systems, such as Windows, many characters that do not have a dedicated key combination on the keyboard may nevertheless be entered using the Alt code (the Alt numpad input method ). This is done by pressing and holding the Alt key, then typing a number on the ...
