Lessons from early Earth: UV surface radiation should not limit the habitability of active M star systems [PDF]

Monthly notices of the Royal Astronomical Society, 2019
The closest potentially habitable worlds outside our Solar system orbit a different kind of star than our Sun: smaller red dwarf stars. Such stars can flare frequently, bombarding their planets with biologically damaging high-energy UV radiation, placing

Habits Revealed

Review of Economic Studies, 2010
This paper sets out necessary and sufficient empirical conditions for rational intrinsic habits models in the revealed preference tradition of Samuelson (1948), Houthakker (1950), Afriat (1967), and Browning (1989). The conditions in the paper are shown to be computationally straightforward and to yield set identification for certain features of the ...

Habitable Climates: The Influence of Eccentricity

, 2010
In the outer regions of the habitable zone, the risk of transitioning into a globally frozen "snowball" state poses a threat to the habitability of planets with the capacity to host water-based life. We use a one-dimensional energy balance climate model (

Multiverse Predictions for Habitability: Fraction of Planets that Develop Life

, 2019
In a multiverse context, determining the probability of being in our particular universe depends on estimating its overall habitability compared to other universes with different values of the fundamental constants.

THE DRINK HABIT. [PDF]

JAMA: The Journal of the American Medical Association, 1892
ABSTRACT In discussing the above subject I start out with these propositions: 1, That any ailment which can be cured by moral suasion, religious enthusiasm or simple will power can not be organic in origin. 2, That the drink babit is curable by the above methods. 3, The drink habit is not primarily a disease of any organ.

Habitability of Super-Earth Planets around Main-Sequence Stars including Red Giant Branch Evolution: Models based on the Integrated System Approach

, 2011
In a previous study published in Astrobiology, we focused on the evolution of habitability of a 10 M_E super-Earth planet orbiting a star akin to the Sun.

Semi-Empirical Estimates of the Cosmic Planet Formation Rate

Galaxies
We devise and exploit a data-driven, semi-empirical framework of galaxy formation and evolution, coupling it to recipes for planet formation from stellar and planetary science, to compute the cosmic planet formation rate, and the properties of the ...

Carbonation and decarbonation reactions: Implications for planetary habitability

American Mineralogist, 2019
The geologic carbon cycle plays a fundamental role in controlling Earth’s climate and habitability. For billions of years, stabilizing feedbacks inherent in the cycle have maintained a surface environment that could sustain life.
