WebbA stellar atmosphere is the outer region of a star, which includes the layers above the opaque photosphere; stars of low temperature might have outer atmospheres containing compound molecules . The … WebbFör 1 dag sedan · The atmospheric composition of planets is determined by the chemistry of the disks in which they form. Studying the gas-phase molecular composition of disks thus allows us to infer what the atmospheric composition of forming planets might be. Recent observations of the IRS 48 disk have shown that (asymmetric) dust traps can …

WebbThe general characteristics of the spectra of stars depend more on temperature variations among the stars than on their chemical differences. Spectral features also depend on the density of the absorbing atmospheric matter, and density in turn is related to a star’s surface gravity. Dwarf stars, with great surface gravities, tend to have high atmospheric … WebbThe distribution of surface gravities shows that almost 90% of the host stars are dwarf stars, and half of the remaining stars are in roughly equal parts subgiants or giant stars. …
