The Spectral Character of Giant Planets and Brown Dwarfs
A. Burrows, M. Marley, W. B. Hubbard +6
Since October of 1995, employing Doppler spectroscopy astronomers have discovered as many as 20 giant planets and brown dwarfs, including companions to Boo, 51 Peg, …
Advances in the Theory of Extrasolar Giant Planets and Brown Dwarfs
A. Burrows, D. Sudarsky, C. Sharp +6
We have developed a new non-gray theory of the evolution, spectra, and colors of extrasolar giant planets (EGPs) and brown dwarfs that reveals their exotic nature and uniqueness. W…
Design and early operation of a new-generation internal beam dump for CERN's Super Proton Synchrotron
A. Romero Francia, A. Perillo Marcone, S. Pianese +22
The Super Proton Synchrotron (SPS) is the last stage in the injector chain for CERN's Large Hadron Collider, and it also provides proton and ion beams for several fixed-target expe…
Design, development, and construction of the new beam stoppers for CERN's injector complex
D. Baillard, E. Grenier-Boley, M. Dole +9
Beam stoppers are installed in the transfer lines of the CERN accelerator complex; these components are used as part of the access safety system, which guarantees the safety of wor…
Chemical Equilibrium Abundances in Brown Dwarf and Extrasolar Giant Planet Atmospheres
A. Burrows, C. Sharp
We calculate detailed chemical abundance profiles for a variety of brown dwarf and extrasolar giant planet atmosphere models, focusing in particular on Gliese 229B, and derive the…
Design and behaviour of the Large Hadron Collider external beam dumps capable of receiving 539 MJ/dump
J. Maestre, C. Torregrosa, K. Kershaw +18
Two 6-t beam dumps, made of a graphite core encapsulated in a stainless steel vessel, are used to absorb the energy of the two Large Hadron Collider (LHC) intense proton beams duri…
A Non-Gray Theory of Extrasolar Giant Planets and Brown Dwarfs
A. Burrows, M. Marley, W. B. Hubbard +6
We present the results of a new series of non-gray calculations of the atmospheres, spectra, colors, and evolution of extrasolar giant planets (EGPs) and brown dwarfs for effective…
