The potassium absorption on HD189733b and HD209458b
Engin Keles, Matthias Mallonn, Carolina von Essen +9
In this work, we investigate the potassium excess absorption around 7699A of the exoplanets HD189733b and HD209458b. For this purpose, we used high spectral resolution transit obse…
Low albedos of hot to ultra-hot Jupiters in the optical to near-infrared transition regime
M. Mallonn, J. Köhler, X. Alexoudi +4
The depth of a secondary eclipse contains information of both the thermally emitted light component of a hot Jupiter and the reflected light component. If the dayside atmosphere of…
Ephemeris refinement of 21 Hot Jupiter exoplanets with high timing uncertainties
M. Mallonn, C. von Essen, E. Herrero +32
Transit events of extrasolar planets offer a wealth of information for planetary characterization. However, for many known targets, the uncertainty of their predicted transit windo…
