Impact of atmospheric refraction: How deeply can we probe exo-Earth's atmospheres during primary eclipse observations?
Y. Betremieux, L. Kaltenegger
Most models used to predict or fit exoplanet transmission spectra do not include all the effects of atmospheric refraction. Namely, the angular size of the star with respect to the…
Exploring atmospheres of hot mini-Neptunes and extrasolar giant planets orbiting different stars with application to HD 97658b, WASP-12b, CoRoT-2b, XO-1b and HD 189733b
Yamila Miguel, Lisa Kaltenegger
We calculated an atmospheric grid for hot mini-Neptune and giant exoplanets, that links astrophysical observable parameters- orbital distance and stellar type- with the chemical at…
Transmission spectrum of Earth as a transiting exoplanet - from the ultraviolet to the near-infrared
Y. Betremieux, L. Kaltenegger
Transmission spectroscopy of exoplanets is a tool to characterize rocky planets and explore their habitability. Using the Earth itself as a proxy, we model the atmospheric cross se…
Atmospheric mass loss and evolution of short-period exoplanets: the examples of CoRoT-7b and Kepler-10b
Hiroyuki Kurokawa, Lisa Kaltenegger
Short-period exoplanets potentially lose envelope masses during their evolution because of atmospheric escape caused by the intense XUV radiation from their host stars. We develop…
Calculating the Habitable Zone of Binary Star Systems II: P-Type Binaries
N. Haghighipour, L. Kaltenegger
We have developed a comprehensive methodology for calculating the circumbinary HZ in planet-hosting P-type binary star systems. We present a general formalism for determining the c…
Calculating the Habitable Zone of Binary Star Systems I: S-Type Binaries
L. Kaltenegger, N. Haghighipour
We have developed a comprehensive methodology for calculating the boundaries of the habitable zone (HZ) of planet-hosting S-type binary star systems. Our approach is general and ta…
