A Swift view of X-ray and UV radiation in the planet-forming T-Tauri system PDS 70
Simon Joyce, John Pye, Jonathan Nichols +4
PDS 70 is a 5 Myr old star with a gas and dust disc in which several proto-planets have been discovered. We present the first UV detection of the system along with X-ray obse…
Exoplanet host-star properties: the active environment of exoplanets
John P. Pye, David Barrado, Rafael A. Garcia +12
The primary objectives of the ExoplANETS-A project are to: establish new knowledge on exoplanet atmospheres; establish new insight on influence of the host star on the planet atmos…
The white dwarf mass-radius relation and its dependence on the hydrogen envelope
Alejandra D. Romero, S. O. Kepler, S. R. G. Joyce +2
We present a study of the dependence of the mass-radius relation for DA white dwarf stars on the hydrogen envelope mass and the impact on the value of log g, and thus the determina…
