Escape and evolution of Titan's N atmosphere constrained by N/N isotope ratios
N. V. Erkaev, M. Scherf, S. E. Thaller +4
We apply a 1D upper atmosphere model to study thermal escape of nitrogen over Titan's history. Significant thermal escape should have occurred very early for solar EUV fluxes 100 t…

Modeling the Ly transit absorption of the hot Jupiter HD 189733b
P. Odert, N. V. Erkaev, K. G. Kislyakova +7
Hydrogen-dominated atmospheres of hot exoplanets expand and escape due to the intense heating by the X-ray and extreme ultraviolet (XUV) irradiation of their host stars. Excess abs…

Supermassive Hot Jupiters Provide More Favourable Conditions for the Generation of Radio Emission via the Cyclotron Maser Instability - A Case Study Based on Tau Bootis b
C. Weber, N. V. Erkaev, V. A. Ivanov +5
We investigate under which conditions supermassive hot Jupiters can sustain source regions for radio emission, and whether this emission could propagate to an observer outside the…
