Revisiting the exomoon candidate signal around Kepler-1625b
Kai Rodenbeck, René Heller, Michael Hippke +1
Transit photometry of the exoplanet candidate Kepler-1625b has recently been interpreted to show hints of a moon. We aim to clarify whether the exomoon-like signal is really caused…
Exploring exomoon atmospheres with an idealized general circulation model
Jacob Haqq-Misra, René Heller
Recent studies have shown that large exomoons can form in the accretion disks around super-Jovian extrasolar planets. These planets are abundant at about 1 AU from Sun-like stars,…
Formation of hot Jupiters through disk migration and evolving stellar tides
René Heller
Here we address the hot Jupiter (hJ) pile-up at 0.05 AU around young solar-type stars observed in stellar radial velocity surveys, the hJ longterm orbital stability in the presence…
Investigating Planet Formation and Evolutionary Processes with Short-Period Exoplanets
Brian Jackson, Elisabeth Adams, René Heller +1
From wispy gas giants on the verge of disruption to tiny rocky bodies already falling apart, short-period exoplanets pose a severe puzzle to theories of planet formation and orbita…
