History and Habitability of the LP 890-9 Planetary System [PDF]

The 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

Anomalous transient enhancement of planetary ion escape at Mars [PDF]

Nature Communications
Atmospheric ion escape plays a crucial role in the evolution of planetary climate and habitability. While Mars has been the focus of extensive in-situ spacecraft observations, our understanding of ion escape at Mars has been constrained by single-point ...

Eccentricity Distribution beyond the Snow Line and Implications for Planetary Habitability [PDF]

The Astrophysical Journal Letters
A fundamental question in the study of planetary system demographics is: how common is the solar system architecture? The primary importance of this question lies in the potential of planetary systems to create habitable environments, and dissecting the ...

Quantifying the Key Factors Affecting the Escape of Planetary Atmospheres

The Astrophysical Journal, 2023
The habitability of Earth-like planets is an increasingly important subject in astrophysics and in planetary sciences. Atmospheric escape plays a vital role in the evolution of the habitability of Earth-like planets.

Hard rock dark biosphere and habitability

Frontiers in Astronomy and Space Sciences, 2023
The discovery that most of the prokaryotic diversity and biomass on Earth resides in the deep subsurface, calls for an improved definition of habitability, which should consider the existence of dark biospheres in other planets and moons of the Solar ...

Impact of Changing Stellar and Planetary Magnetic Fields on (Exo)planetary Environments and Atmospheric Mass Loss

The Astrophysical Journal, 2023
The magnetic activity of a star—which modulates the stellar wind outflow—shapes the immediate environments of orbiting (exo)planets and induces atmospheric loss, thereby impacting their habitability.
