Atmospheric line


  • Webster's Revised Unabridged Dictionary
    • Atmospheric line (Steam Engin) the equilibrium line of an indicator card. Steam is expanded “down to the atmosphere” when its pressure is equal to that of the atmosphere. (See Indicator card

Recently, it is a central goal and a real competition among the observers to find line emission from the atmosphere, since the stellar mass M and radius R may be derived by obtaining its gravitational redshift (as M/R) and the pressure broadening (as M/R2) of the lines.
What can the redshift observed in EXO 0748-676 tell us?
I describe recent progress in terms of 3D hydrodynamical model atmospheres and 3D line formation and their applications to stellar abundance analyses of late-type stars.

In spite of their still inferior treatment of radiative transfer and line blanketing compared with existing 1D model atmospheres based on the mixing length theory, detailed comparisons with a range of observational diagnostics suggest that these simulations are indeed highly realistic.

The temporal evolution of the simulations cover several convective turn-over time-scales to allow thermal relaxation to be established and to obtain statistically significant average atmospheric structures and spectral line profiles.

The 3D hydrodynamical model atmospheres described in the previous section form the basis for the 3D spectral line formation calculations.

The realistic 3D hydrodynamical model atmospheres of late-type stars together with corresponding LTE and non-LTE line formation tools described above have a natural application to stellar abundance analyses.
Stellar abundance analyses in the light of 3D hydrodynamical model atmospheres
For abundance studies, the different mean photospheric structure between 3D and 1D models, the existence of atmospheric inhomogenities and the broadening of spectral lines due to convective motions are all important ingredients for the line formation.

The effect of the blending Ni i line reduces the derived abundance significantly (−0.13 dex), while the transition from 1D to 3D model atmospheres and a revised gf -value are of less importance (−0.08 and −0.03 dex, respectively) but compounds the overall difference.

For the present study of HD 50896, we employ CMFGEN (Hillier & Miller 1998), which solves the transfer equation in the co-moving frame sub ject to statistical and radiative equilibrium, assuming an expanding, spherically-symmetric, homogeneous and static atmosphere, allowing for line blanketing and clumping.
