Externally Dispersed Interferometry for Precision Radial Velocimetry
D. J. Erskine, M. W. Muterspaugh, J. Edelstein +5
Externally Dispersed Interferometry (EDI) is the series combination of a fixed-delay field-widened Michelson interferometer with a dispersive spectrograph. This combination boosts…

Radiative Transfer Modeling of Passive Circumstellar Disks: Application to HR4796A
T. Currie, D. Semenov, Th. Henning +2
We present a radiative transfer model which computes the spectral energy distribution of a passive, irradiated, circumstellar disk, assuming the grains are in radiative equilibrium…
