absorptance

Definitions

  • WordNet 3.6
    • n absorptance a measure of the rate of decrease in the intensity of electromagnetic radiation (as light) as it passes through a given substance; the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber "absorptance equals 1 minus transmittance"

In science:

EWc = 1.3 ˚A is a reasonable approximation for the stellar absorption correction when using the SDSS pipeline spectral line measurements, and corresponds roughly to a 2.6 ˚A EW stellar absorption in the SF galaxies.
Star formation rate indicators in the Sloan Digital Sky Survey
The solid line is the SDSS pipeline Gaussian fit to the emission, and the dashed lines are a double Gaussian fit, made by fixing an absorption component to have an EW= 3.0 ˚A the same EW as the absorption measured at Hδ in this spectrum.
Star formation rate indicators in the Sloan Digital Sky Survey
The [Ne III] λ3968 emission is confused by Hǫ emission and absorption and by Ca II H absorption, but its ratio of 1/3 (in photon units) to the stronger [Ne III] λ3869 line allows it to be subtracted quite accurately.
The Aligned z ~ 1 Radio Galaxy 3C 280
No surprise that the X-ray afterglows tend to show Fe and Mg in their early (redshifted) absorption spectra, in particular strong Fe K-edge absorption (Amati et al 2000), scraped off a neutron star’s surface.
Gamma-Ray Bursts: their Sources
This is expected, due to heating of the particle which results from the absorption of light through the sample, and also heating of the surrounding liquid due to absorption of the trapping beam by water, which is on the order of 10 K per W at the focus .

We therefore performed a spectral fit by adopting a simple power law model with two photoelectric absorption component: one representing the absorption from our Galaxy and the other representing the additional absorption along the line of sight.
Absorption in Gamma Ray Burst afterglows
The drift towards the absorption point may be attributed to two distinct reasons: (i) A smaller (average) probability to take a step to the right (away from the absorption point).

Brouwer demonstrated that Eq.(2) is inapplicable in the limit of strong absorption [17, 18], whereas we are interested in the weakly absorbing systems with √Dτ > L, where D is the diffusion coefficient, and τ is the absorption time.
Effects of localization and amplification on distribution of intensity transmitted through random media
In addition to the emission features, there are strong absorption lines of Ca II, Fe I, and Ti I in the wavelength region from approximately 8400 to 8700˚A that are relatively free from molecular absorption bands so they can be confidently used for radial velocity measurements.

This may be an inverse P Cygni profile, but the broad absorption minimum has a red-shifted velocity, typically ∼ 86 km s−1 (Table 5) like the other reflected absorption lines at the same positions (see §4.1).

The line is very narrow, does not show the multiple peaks observed in the K I line, and has essentially a constant Doppler velocity at ≈ 41 km s−1 like that for the K I emission on the star (Table 4). A strong, reflected absorption line which we attribute to Ca I] absorption is present in the ejecta.
