About Me

I am a postdoctoral researcher working at the Department of Astrophysics at the University of Vienna. I am also a member of the Pathways to Habitability project, which includes different groups of scientists in Austria and a broad cooperation abroad, and a remote member of the exoplanetary group of the Space Research Institute in Graz, Austria.

Magma oceans and enhanced volcanism on TRAPPIST-1 planets due to induction heating

We suggest electromagnetic induction heating as an energy source inside TRAPPIST-1 planets. We show that it can lead the four innermost planets, one of which is in the habitable zone, either to evolve towards a molten mantle planet, or to experience increased outgassing and volcanic activity, while the three outermost planets remain mostly unaffected.

On the ultraviolet anomalies of the WASP-12 and HD 189733 systems: Trojan satellites as a plasma source

We suggest an additional possible plasma source to explain part of the phenomena observed for the transiting hot Jupiters WASP-12b and HD 189733b in their ultraviolet (UV) light curves. In the proposed scenario, material outgasses from the molten surface of Trojan satellites on tadpole orbits near the Lagrange points.

Magnetic moment and plasma environment of HD 209458b as determined from Lyα observations

We reproduced the transit observations of HD 209458b in the stellar Lyα line by means of modeling. Our results support a planetary magnetic moment of 10% of the magnetic moment of Jupiter.

Stellar wind interaction and pick-up ion escape of the Kepler-11 "super-Earths"

Kepler-11 planets likely possess hydrogen dominated atmospheres. We show that all super-Earths in this system experience strong atmospheric losses, with non-thermal losses being an approximately 10% fraction of the thermal escape.
