چکیده
Theoretical spectra and evolutionary models that span the giant planet–brown dwarf continuum have been computed based on the recent discovery of the brown dwarf, Gliese 229 B. A flux enhancement in the 4–5 micron window is a universal feature from Jovian planets to brown dwarfs. We confirm the existence of methane and water in Gl 229 B's spectrum and find its mass to be 30 to 55 Jovian masses. Although these calculations focus on Gliese 229 B, they are also meant to guide future searches for extra-solar giant planets and brown dwarfs.

We have used the coronographic instrument CoCo with the IRTF’s facility camera NSFCAM to obtain improved photometry at JHKL of the giant planet/brown dwarf Gliese 229B. We have recalibrated the published spectra for this object, and re–calculated its luminosity. Our L value, and our flux calibration of the spectra at JHK, are significantly different from those previously published. Our results ...

We present low resolution spectrophotometric and imaging ISO observations of a sample of 54 AGN's over the 2.5–11 µ range. The observations generally support unification schemes and set new constraints on models of the molecular torus.
