The stellaratmosphere is the outer region of the volume of a star, lying above the stellar core, radiation zone and convection zone. The stellar atmosphere...
object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellaratmosphere is the outer region of...
disappearances of absorption lines in the stellar sequence, assuming an order of magnitude for the pressure in a stellaratmosphere and calculating the temperature...
of the photosphere is the stellaratmosphere. In a main sequence star such as the Sun, the lowest level of the atmosphere, just above the photosphere...
A stellar wind is a flow of gas ejected from the upper atmosphere of a star. It is distinguished from the bipolar outflows characteristic of young stars...
Radcliffe College, in which she applied Saha's ionization theory to stellaratmospheres to relate the spectral classes to the temperature of stars. Most...
the stellar envelope, which transports energy from the core to the stellaratmosphere where it is radiated away into space. Main sequence stars are distinguished...
In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is...
been found on the Sun, and there is evidence of H2 in white dwarf stellaratmospheres. Cooler stars include absorption band spectra that are characteristic...
emission may arise in molecular clouds, comets, planetary atmospheres, stellaratmospheres, or various other conditions in interstellar space. Like a...
certain value of the Rosseland optical depth (usually 1) within the stellaratmosphere. The effective temperature and the bolometric luminosity are the two...
outer layers known as stellaratmospheres that produce the radiation observed from the Earth. He considered a grey atmosphere, a simplifying approximation...
reverse the stations' fall. This would "squeeze" the star, propelling stellaratmosphere through the polar magnetic nozzles. The ring current would be shut...
the stellaratmosphere; or another name for the stellaratmosphere itself. 2. The common envelope of gases encompassing a binary star system. stellar evolution...
indication of a hot stellaratmosphere, or gas clouds surrounding the star. In very few cases it is possible to make pictures of a stellar disk. These may...
charges, which are typically free protons under the conditions in stellaratmospheres. When the outward electric field is sufficient to levitate the protons...
close enough they can gravitationally distort each other's outer stellaratmospheres. In some cases, these close binary systems can exchange mass, which...
flash phase is primarily due to thermal radiation from the heated stellaratmosphere. As the material reaches the corona, the intensive release of energy...
grey atmosphere (or gray) is a useful set of approximations made for radiative transfer applications in studies of stellaratmospheres (atmospheres of stars)...
temperatures. Existence of the atmosphere of Pluto was proven via stellar occultation. If a star is occulted by a body without an atmosphere, its light disappears...
within 10 to 100 million years. The effective temperature of the stellaratmosphere is an estimated 6,530 K, giving Procyon A a white hue. It is 1.5 times...
The spectral signature of stars indicates the composition of the stellaratmosphere. The spectral signature of an object is a function of the incidental...
star, but not in a planet's atmosphere. Subrahmanyan Chandrasekhar (1950, page 290) writes of a model of a stellaratmosphere in which "there are no mechanisms...
star. Later in its life, a low-mass star will slowly eject its atmosphere via stellar wind, forming a planetary nebula, while a higher–mass star will...
