Extreme hydrodynamic atmospheric loss near the critical thermal escape regime

Nikolai V. Erkaev, Helmut Lammer, P. Odert, Yu. N. Kulikov et autres

By considering martian-like planetary embryos inside the habitable zone of solar-like stars we study the behaviour of the hydrodynamic atmospheric escape of hydrogen for small values of the Jeans escape parameter β < 3, near the base of the thermosphere, that is …

Origin and loss of nebula-captured hydrogen envelopes from ‘sub’- to ‘super-Earths’ in the habitable zone of Sun-like stars

Helmut Lammer, A. Stökl, Nikolai V. Erkaev, E. A. Dorfi et autres

We investigate the origin and loss of captured hydrogen envelopes from protoplanets having masses in a range between ‘sub-Earth’-like bodies of 0.1 M⊕ and ‘super-Earths’ with 5 M⊕ in the habitable zone at 1 au of a Sun-like G star, assuming that …

Escape of the martian protoatmosphere and initial water inventory

Nikolai V. Erkaev, Helmut Lammer, Linda T. Elkins-Tanton, A. Stökl et autres

Latest research in planet formation indicates that Mars formed within a few million years (Myr) and remained as a planetary embryo that never grew to a more massive planet. It can also be expected from dynamical models that most of Mars' building …

Solar flares as proxy for the young Sun: satellite observed thermosphere response to an X17.2 flare of Earth's upper atmosphere

Sandro Krauß, Bibiana Fichtinger, Helmut Lammer, Walter Hausleitner et autres

Abstract. We analyzed the measured thermospheric response of an extreme solar X17.2 flare that irradiated the Earth's upper atmosphere during the so-called Halloween events in late October/early November 2003. We suggest that such events can serve as proxies for the intense electromagnetic …

Erratum to “Could CoRoT-7b and Kepler-10b be remnants of evaporated gas or ice giants?”

M. Leitzinger, P. Odert, Yu. N. Kulikov, Helmut Lammer et autres

The authors regret that a graphical error (wrong y-axis labeling) in the lower right panel of Fig. 3 has occurred.The caption of Fig. 3 had to be corrected too, according to the arrangement of the panels.Furthermore the panels of Fig. 1 needed …

Could CoRoT-7b and Kepler-10b be remnants of evaporated gas or ice giants?

M. Leitzinger, P. Odert, Yu. N. Kulikov, H. Lammer et autres

We present thermal mass loss calculations over evolutionary time scales for the investigation if the smallest transiting rocky exoplanets CoRoT-7b (∼1.68REarth) and Kepler-10b (∼1.416REarth) could be remnants of an initially more massive hydrogen-rich gas giant or a hot Neptune-class exoplanet. We apply …
