Multiwaveband photometry of the irradiated brown dwarf WD0137-349B
S. L. Casewell, K. A. Lawrie, P. F. L. Maxted +7
WD0137-349 is a white dwarf-brown dwarf binary system in a 116 minute orbit. We present radial velocity observations and multiwaveband photometry from V, R and I in the optical, to…
Ionization in Atmospheres of Brown Dwarfs and Extrasolar Planets V: Alfvén Ionization
Craig R. Stark, Christiane Helling, Declan A. Diver +1
Observations of continuous radio and sporadic X-ray emission from low-mass objects suggest they harbour localized plasmas in their atmospheric environments. For low-mass objects, t…
Ionization in atmospheres of Brown Dwarfs and extrasolar planets IV. The Effect of Cosmic Rays
Paul Rimmer, Christiane Helling
Cosmic rays provide an important source for free electrons in the Earth's atmosphere and also in dense interstellar regions where they produce a prevailing background ionization. W…
