Astrophysical plasma 1970-01-01
Astrophysical plasma refers to a state of matter consisting of ionized gas found in various celestial environments throughout the universe. Plasma is one of the four fundamental states of matter, alongside solid, liquid, and gas. It is formed when gas is heated to high temperatures or when it is subjected to a strong electromagnetic field, causing atoms to lose electrons and resulting in a collection of charged particles, including ions and free electrons.
Blazhko effect 1970-01-01
The Blazhko effect is a phenomenon observed in certain types of variable stars known as RR Lyrae stars. Named after the astronomer Sergei Blazhko, who first described it in 1907, the effect is characterized by the modulation of the brightness and pulsation period of these stars.
Blue giant 1970-01-01
A blue giant is a type of star that is very hot and massive, typically characterized by its blue color and high luminosity. These stars are part of the larger classification of stars based on their temperature and size. Blue giants usually have a surface temperature exceeding 10,000 Kelvin (as opposed to the Sun's surface temperature of about 5,500 Kelvin) and can be significantly more massive than the Sun, often ranging from about 10 to 100 solar masses.
Hořava–Witten theory 1970-01-01
Hořava-Witten theory is a framework in theoretical physics that emerged in the context of string theory and M-theory. Proposed by Petr Hořava and Edward Witten in 1996, the theory seeks to provide a consistent way to construct non-perturbative theories based on M-theory, which is believed to unify all five superstring theories.
Concrete Roman 1970-01-01
Concrete Roman is a typeface designed by the typographer and designer Fredrik H. Schmidt, often characterized by its geometric forms and strong typographic presence. It blends classical Roman letterforms with a modern, structural aesthetic, reflecting a certain solidity and clarity that appeals to contemporary design sensibilities. The design of Concrete Roman often incorporates clean lines and a sturdy appearance, making it suitable for various applications, such as branding, signage, and editorial design.
Device independent file format 1970-01-01
Device Independent File Format (DIFF) is a file format designed to store graphical or audio-visual content in a way that is independent of the specific hardware or software used to create or display the content. The idea behind DIFF is to ensure that the file can be rendered consistently across different devices and platforms, regardless of their individual characteristics or capabilities. ### Key Features 1.
Grapher 1970-01-01
Grapher is a graphing and visualization software developed by Apple that allows users to create a wide variety of 2D and 3D graphs. It is part of the macOS operating system and provides tools for plotting functions, data points, and mathematical expressions. Users can customize the appearance of their graphs, add annotations, and manipulate the properties of the axes and gridlines.
List of TeX extensions 1970-01-01
TeX is a typesetting system that has been extended in various ways to enhance its capabilities, add new features, and improve its usability in different contexts. Here are some notable extensions and packages associated with TeX, particularly LaTeX, which is a widely used document preparation system built on top of TeX: ### Commonly Used LaTeX Packages and Extensions 1. **amsmath** - Provides advanced math typesetting features and environments.
Lucida 1970-01-01
"Lucida" can refer to several things, depending on the context: 1. **Lucida Fonts**: A family of typefaces designed by Charles Bigelow and Kris Holmes. The Lucida font family includes various styles such as Lucida Grande, Lucida Sans, and Lucida Serif, and is known for its readability and clarity, making it popular for both print and digital applications.
MathTime 1970-01-01
MathTime is a term that could refer to different things depending on the context. Here are a couple of possibilities: 1. **Mathematical Software or Tools**: It might refer to software or online tools that assist with mathematics, such as equation editors, calculators, or educational platforms designed to help students learn math. 2. **Educational Programs**: In some educational contexts, "MathTime" could be the name of a program or initiative aimed at improving math skills for students of various ages.
Alan Lindsay Mackay 1970-01-01
Alan Lindsay Mackay is a prominent Australian mathematician known for his work in the field of mathematics, particularly in relation to partial differential equations and mathematical analysis. He has contributed significantly to various areas within mathematics and has published numerous papers throughout his career.
Facula 1970-01-01
"Facula" is a term used in astronomy and planetary science to refer to bright or reflective spots on the surface of celestial bodies, primarily on the Moon and planets. These features typically consist of relatively high-albedo material, which means they reflect more sunlight than their surrounding areas. On the Moon, faculae are often associated with impact craters and volcanic activity. They can be found in both the dark, basaltic plains (maria) as well as the bright highlands.
Gravity darkening 1970-01-01
Gravity darkening is a phenomenon in astrophysics that describes how the brightness of a star varies across its surface due to the effects of gravity. This effect is most pronounced in rotating stars, where the centrifugal force caused by rotation causes the star to become oblate, meaning it is flattened at the poles and bulging at the equator. In such stars, the gravitational field strength is not uniform across the surface; it is stronger at the poles and weaker at the equator.
Helioseismology 1970-01-01
Helioseismology is the study of the structure and dynamics of the Sun through the observation of waves propagating within it. By analyzing these oscillations, which are caused by various types of waves (acoustic, gravity, and surface waves), scientists can gain insights into the Sun's internal structure, including temperature, density, and composition.
Hypergiant 1970-01-01
Hypergiant is a term that can refer to several different concepts, so context is important. In a literal astronomical sense, a hypergiant star is a very massive star that is much larger than a typical giant star. These stars have exceptionally high luminosity and can have masses ranging from about 25 to 100 times that of the Sun.
Intermediate luminosity optical transient 1970-01-01
Intermediate luminosity optical transients (ILOTs) refer to a class of astronomical events characterized by significant increases in optical brightness over relatively short timescales, typically lasting from days to weeks. These transients are believed to occur in a variety of contexts, but they are often associated with the explosive or eruptive activity of massive stars, particularly those in the later stages of their evolution.
Kilonova 1970-01-01
A kilonova is an astronomical event that occurs when two neutron stars (or a neutron star and a black hole) merge. This extreme event produces a significant amount of energy and is characterized by a rapid increase in brightness, typically lasting from a few days to weeks. Kilonovae are expected to be a source of heavy elements such as gold and platinum, as the collision releases an intense amount of energy in the form of gravitational waves and electromagnetic radiation.
Limb darkening 1970-01-01
Limb darkening is an effect observed in the spectra and brightness of celestial bodies, particularly stars and planets. It refers to the phenomenon where the edges (or "limbs") of a star or planet appear darker than the center when viewed in terms of brightness or intensity. This effect arises due to the temperature gradient in the outer layers of a star. The center of the star is generally hotter and emits more light than the outer edges or "limbs.
Radiative levitation 1970-01-01
Radiative levitation is a physical phenomenon that occurs when an object is suspended in space due to the balance between the forces of radiation pressure and gravitational pull. This effect is most commonly observed in environments where the radiation intensity is high, such as in stellar atmospheres or in the vicinity of certain types of lasers. In radiative levitation, the force exerted by the radiation (typically photons) can counteract the force of gravity.
