Spectral Analysis Quiz - Level 2
Spectral Analysis Quiz
Above 1 kev, the dominant cooling mechanism for an astrophysical plasma is
[A] spectral line emission
[B] convection
[C] characterized by their continual emission
[D] none of the above
Blackbody radiation is the result of
[A] particles interacting with a magnetic field
[B] particles annihilating with other particles
[C] particles interacting with photons so that thermalization occurs
[D] particles being captured in the atmosphere of Earth
In most X-ray systems, the plasmas are transparent enough that
[A] the resulting spectrum is a good representation of the processes occurring in the emitting gas
[B] no spectral lines can be seen
[C] the X-rays are usually absorbed by ambient dust
[D] all of the above
The spectrum determined by an X-ray detector is a convolution of
[A] the preconceptions of the astronomer and the incident spectrum
[B] nuclear episodes on neutron star surfaces and atmospheric plasma density
[C] line emission profiles and the mathematical model used
[D] the response of the detector and the incident spectrum
