Lightning climatology of exoplanets and brown dwarfs guided by Solar System data
Gabriella Hodosán, Christiane Helling, Rubén Asensio-Torres +2
Clouds form on extrasolar planets and brown dwarfs where lightning could occur. Lightning is a tracer of atmospheric convection, cloud formation and ionization processes as known f…
VULCAN: an Open-Source, Validated Chemical Kinetics Python Code for Exoplanetary Atmospheres
Shang-Min Tsai, James R. Lyons, Luc Grosheintz +3
We present an open-source and validated chemical kinetics code for studying hot exoplanetary atmospheres, which we name VULCAN. It is constructed for gaseous chemistry from 500 to…
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…
Jupiter as a Giant Cosmic Ray Detector
Paul B. Rimmer, Craig R. Stark, Christiane Helling
We explore the feasibility of using the atmosphere of Jupiter to detect Ultra-High-Energy Cosmic Rays (UHECR's). The large surface area of Jupiter allows us to probe cosmic rays of…
Disk evolution, element abundances and cloud properties of young gas giant planets
Ch. Helling, P. Woitke, P. B. Rimmer +3
We discuss the chemical pre-conditions for planet formation, in terms of gas and ice abundances in a protoplanetary disk, as function of time and position, and the resulting chemic…
