Probability Distribution of Terrestrial Planets in Habitable Zones around Host Stars [PDF]
Published on Ap&SS, Oct. 2009, 2010 With more and more exoplanets being detected, it is paid closer attention to whether there are lives outside solar system. We try to obtain habitable zones and the probability distribution of terrestrial planets in habitable zones around host stars. Using Eggleton's code, we calculate the evolution of stars with masses less than 4.00 \mo.

Effects of Extreme Obliquity Variations on the Habitability of Exoplanets [PDF]
, 2014 We explore the impact of obliquity variations on planetary habitability in hypothetical systems with high mutual inclination. We show that large amplitude, high frequency obliquity oscillations on Earth-like exoplanets can suppress the ice-albedo ...

A Methane Extension to the Classical Habitable Zone [PDF]
The Astrophysical Journal, 2018 Abstract The habitable zone (HZ) is the circumstellar region where standing bodies of liquid water could exist on the surface of a rocky planet. Conventional definitions assume that CO2 and H2O are the only greenhouse gases. The outer edge of this classical N2–CO2–H2O HZ extends out to nearly ∼1.7 au in our solar system, beyond which ...

Antibacterial Siderophores of Pandoraea Pathogens and Their Impact on the Diseased Lung Microbiota
Angewandte Chemie, EarlyView.Genome mining of environmental and pathogenic Pandoraea species identified a conserved NRPS gene cluster and led to the discovery of novel siderophores, pandorabactins, which exert their antibacterial activity by depleting iron from competitors. Bioinformatic analysis of sputum from cystic fibrosis patients coupled with bioassays indicates that ...

HAZMAT. IX. An Analysis of the UV and X-Ray Evolution of Low-mass Stars in the Era of Gaia
The Astrophysical Journal, 2023 Low-mass stars (≤1 M _⊙ ) are some of the best candidates for hosting planets with detectable life because of these stars’ long lifetimes and relative ratios of planet to star mass and radius.

Photosynthetic Constraints on the Habitable Zone [PDF]
Symposium - International Astronomical Union, 2004 The search for extraterrestrial habitable planets will require long observation times and the intelligent selection of appropriate parent stars and target biosignatures. While life can certainly develop in the absence of photosynthesis, such life forms on earth exhibit metabolic rates several orders of magnitude less than the activity accompanying a ...

A More Comprehensive Habitable Zone for Finding Life on Other Planets
Geosciences, 2018 The habitable zone (HZ) is the circular region around a star(s) where standing bodies of water could exist on the surface of a rocky planet. Space missions employ the HZ to select promising targets for follow-up habitability assessment.

Bypassing the habitable zone [PDF]
Nature Geoscience, 2017 In our own solar system, Venus is too hot, Mars is too cold and Earth is just right. Simulations show that making an icy planet habitable is not as simple as melting its ice: many icy bodies swing from too cold to too hot, bypassing just right.
