Furthermore, when one's service to the Nation comes to a close, we give back to society a stellar model citizen who understands that actions have cause and effect and that living a life ready for inspection is a foundation gained from military service.
To each star in the HR diagram a stellar model is assigned based on the effective temperature and gravity.
"We anticipate the ultimate range of rich user experiences offered on this stellar model from the Xperia range to increase the momentum several times over in key MENA markets."

By comparing different CRM models and applying the inductive method a hexagonal stellar model was designed.
In this paper, Stromgren sought to answer how the addition of helium would change his stellar model. The only observational basis to support a helium hypothesis was estimates of relative amounts of hydrogen and helium, but determinations were rather weak.
Since the early 1970s, the district taught a comprehensive family life education course, acknowledged by the Minnesota Department of Education as a stellar model. As part of the district's seven-year curriculum evaluation, the program was reviewed.
The August 2017 workshop was in Kalamazoo, Michigan and the 40 papers that emerged cover stellar opacities and the solar abundance problem; the computation and measurement of atomic opacities and molecular opacities; stellar atomic diffusion; stellar models; brown dwarfs, exoplanets, and protoplanetary disks; and astrophysical processes and atomic data.
That said, high-precision results from the latest method could also help astronomers improve replicas of stellar models designed to study the characteristics of new and old stars, and their evolution.
We also discuss models and factors which may affect opacity, as this is a preponderant parameter for radiative heat transfer, a key component of stellar models. For stellar models we also need boundary conditions such as the density of the photosphere.
