Stellar flares versus luminosity: XUV-induced atmospheric escape and planetary habitability [PDF]

open access: bronzeMonthly Notices of the Royal Astronomical Society: Letters, 2020
Space weather plays an important role in the evolution of planetary atmospheres. Observations have shown that stellar flares emit energy in a wide energy range (1030–1038 erg), a fraction of which lies in X-rays and extreme ultraviolet (XUV).

Planetary Magnetic Fields and Habitability in Super Earths

open access: yesOpen Astronomy, 2018
This work seeks to summarize some special aspects of a type of exoplanets known as super-Earths (SE), and the direct influence of these aspects in their habitability.

Long-Term Planetary Habitability and the Carbonate-Silicate Cycle [PDF]

open access: yesAstrobiology, 2018
The potential habitability of an exoplanet is traditionally assessed by determining whether its orbit falls within the circumstellar “habitable zone” of its star, defined as the distance at which water could be liquid on the surface of a planet ...

MAGNETIC FIELD AND WIND OF KAPPA CETI: TOWARD THE PLANETARY HABITABILITY OF THE YOUNG SUN WHEN LIFE AROSE ON EARTH [PDF]

open access: green, 2016
We report magnetic field measurements for κ1 Cet, a proxy of the young Sun when life arose on Earth. We carry out an analysis of the magnetic properties determined from spectropolarimetric observations and reconstruct the large-scale surface magnetic ...

Planetary Magnetism as a Parameter in Exoplanet Habitability [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2018
Evidence from the solar system suggests that, unlike Venus and Mars, the presence of a strong magnetic dipole moment on Earth has helped maintain liquid water on its surface. Therefore, planetary magnetism could have a significant effect on the long-term

Tidal Constraints on Planetary Habitability

open access: yes, 2009
We review how tides may impact the habitability of terrestrial-like planets. If such planets form around low-mass stars, then planets in the circumstellar habitable zone will be close enough to their host stars to experience strong tidal forces.

High-Resolution Simulations of The Final Assembly of Earth-Like Planets. 2. Water Delivery And Planetary Habitability [PDF]

open access: greenAstrobiology, 2007
The water content and habitability of terrestrial planets are determined during their final assembly, from perhaps 100 1,000-km “planetary embryos” and a swarm of billions of 1–10-km “planetesimals.” During this process, we assume that water-rich ...

History and Habitability of the LP 890-9 Planetary System

open access: goldThe Planetary Science Journal
We present numerous aspects of the evolution of the LP 890-9 (SPECULOOS-2/TOI-4306) planetary system, focusing on the likelihood that planet c can support life. We find that the host star reaches the main sequence in 1 Gyr and that planet c lies close to
