Frequency of Coronal Mass Ejection Impacts with Early Terrestrial Planets and Exoplanets Around Active Solar-like Stars
Christina Kay, Vladimir S. Airapetian, Theresa Lüftinger +1
Energetic flares and associated coronal mass ejections (CMEs) from young magnetically active solar-like stars can play a critical role in setting conditions for atmospheric escape…
Modeling a Carrington-scale Stellar Superflare and Coronal Mass Ejection from
Benjamin J. Lynch, Vladimir S. Airapetian, C. Richard DeVore +5
Observations from the Kepler mission have revealed frequent superflares on young and active solar-like stars. Superflares result from the large-scale restructuring of stellar magne…
Impact of Space Weather on Climate and Habitability of Terrestrial Type Exoplanets
V. S. Airapetian, R. Barnes, O. Cohen +43
The current progress in the detection of terrestrial type exoplanets has opened a new avenue in the characterization of exoplanetary atmospheres and in the search for biosignatures…
Stellar activity and planetary atmosphere evolution in tight binary star systems
C. P. Johnstone, E. Pilat-Lohinger, T. Lüftinger +2
Context. In tight binary star systems, tidal interactions can significantly influence the rotational and orbital evolution of both stars, and therefore their activity evolution. Th…
Extreme hydrodynamic losses of Earth-like atmospheres in the habitable zones of very active stars
C. P. Johnstone, M. L. Khodachenko, T. Lüftinger +3
Aims. In this letter, we calculate for the first time the full transonic hydrodynamic escape of an Earth-like atmosphere. We consider the case of an Earth-mass planet with an atmos…
HST/STIS analysis of the first main sequence pulsar CU Vir
J. Krticka, Z. Mikulasek, G. W. Henry +9
CU Vir has been the first main sequence star that showed regular radio pulses that persist for decades, resembling the radio lighthouse of pulsars and interpreted as auroral radio…
