Sentences with phrase «observed emission spectrum»

His research culminated in the first observed emission spectrum of an extrasolar planet and revealed tantalizing evidence for the composition of the planet's atmosphere.

That means the emission probability for excited CO2 (and water vapor) is significantly greater than zero and explains the observed emission spectra which show strong CO2 (and water vapor) emission spectral features rather than the continuum emission that would be expected if nitrogen emission dominated.

Not exact matches

«Synchrotron radiation is the only emission mechanism that can create the same degree of polarization and the same spectrum we observed early in the burst,» Troja said.

With such a relatively low mass for the central black hole, models for the emission from the object can not explain the observed spectrum.

The rest goes into pulses observed elsewhere in the electromagnetic spectrum and into cosmic rays, with perhaps some going into the emission of gravitational energy, or gravity waves.

Submillimeter spectra at the emission peak observed with ALMA.

If that is the case and if the continuum is coming in from all directions, then there is no net radiative power transfer going on and in fact, one would not observe any absorption spectra (or emission spectra) at all.

Is there a good link (s) to publicly available literature (no charge preferrable) that shows the agreement between calculated and observed atmospheric IR emission spectra looking up or down or both, or at least some observed spectra that can then be modeled at the Archer site?

Those nice Balmer spectra and the like from Mercury vapor lamps or Sodium lamps and the like are observed in VERY LOW DENSITY gases, where the mean time between molecular or atomic collisions is much longer than the lifetimes of the excited states, so that spontaneous emission can occur; only then do you get the bright line spectra as seen in those HOT gases.
