Accuracy and Precision of Industrial Stellar Abundances [PDF]

Annual Review of Astronomy and Astrophysics, 2019
There has been an incredibly large investment in obtaining high-resolution stellar spectra for determining chemical abundances of stars. This information is crucial to answer fundamental questions in astronomy by constraining the formation and evolution scenarios of the Milky Way as well as the stars and planets residing in it.

Diquark abundance in stellar matter

Physical Review D, 1992
The clustering of quarks into pairs (diquarks) has been suggested recently to play an important role in dense matter and its astrophysical realization in neutron-star cores. We address in this work the features of diquark matter by employing an accurate equation of state valid for the effective {lambda}{phi}{sup 4} diquark theory, and find milder ...

Stellar and Solar Abundances

Space Science Reviews, 1973
Recent spectroscopic results on stellar and solar abundances are reviewed with special reference to (a) Standard abundance distribution (Sun, hot stars, diffuse nebulae); (b) Abundance peculiarities related to stellar evolution (red giants showing results of H-burning and s-process, peculiar and metallic-lined stars); and (c) Population effects that ...

Stellar chemical abundances with the GHRS

Physica Scripta, 1996
The accurate quantitative analysis of high resolution ultraviolet spectra of ultra-sharp-lined early-type, chemically peculiar stars, obtained with the Goddard High Resolution spectrograph on the Hubble Space Telescope, has been made possible by the synergism between state-of-the-art astro-physics and state-of-the-art atomic spectroscopy. We illustrate
