Setting the stage for habitable planets. [PDF]

open access: yesLife (Basel), 2014
Our understanding of the processes that are relevant to the formation and maintenance of habitable planetary systems is advancing at a rapid pace, both from observation and theory.

Albedos, Equilibrium Temperatures, and Surface Temperatures of Habitable Planets. [PDF]

open access: yesAstrophys J, 2019
The potential habitability of known exoplanets is often categorized by a nominal equilibrium temperature assuming a Bond albedo of either ∼0.3, similar to Earth, or 0.

Belatedly Habitable Planets

open access: yesResearch Notes of the AAS, 2021
Stars do not remain static, so their habitable zones evolve in time. Over a star's evolution, its habitable zone encompasses new planets, and it remains uncertain whether these planets can become habitable.

Multiverse Predictions for Habitability: Number of Potentially Habitable Planets [PDF]

open access: yesUniverse, 2019
How good is our universe at making habitable planets? The answer to this depends on which factors are important for life: Does a planet need to be Earth mass? Does it need to be inside the temperate zone? are systems with hot Jupiters habitable? Here, we

Potential long-term habitable conditions on planets with primordial H–He atmospheres [PDF]

open access: yesNature Astronomy, 2022
Cold super-Earths that retain their primordial, H–He-dominated atmosphere could have surfaces that are warm enough to host liquid water. This would be due to the collision-induced absorption of infrared light by hydrogen, which increases with pressure ...

Imaging low-mass planets within the habitable zone of α Centauri [PDF]

open access: yesNature Communications, 2021
Giant exoplanets on wide orbits have been directly imaged around young stars. If the thermal background in the mid-infrared can be mitigated, then exoplanets with lower masses can also be imaged.

Efficiency of the oxygenic photosynthesis on Earth-like planets in the habitable zone [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2021
Oxygenic photosynthesis is the most important biochemical process in Earth biosphere and likely very common on other habitable terrestrial planets, given the general availability of its input chemical ingredients and of light as source of energy. It is

Martian moons exploration MMX: sample return mission to Phobos elucidating formation processes of habitable planets

open access: yesEarth, Planets and Space, 2021
Martian moons exploration, MMX, is the new sample return mission planned by the Japan Aerospace Exploration Agency (JAXA) targeting the two Martian moons with the scheduled launch in 2024 and return to the Earth in 2029.

The Occurrence of Rocky Habitable-zone Planets around Solar-like Stars from Kepler Data [PDF]

open access: yesAstronomical Journal, 2020
We present the occurrence rates for rocky planets in the habitable zones (HZs) of main-sequence dwarf stars based on the Kepler DR25 planet candidate catalog and Gaia-based stellar properties.

Photosynthesis on habitable planets around low-mass stars [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
We show that planets around M-dwarfs with $M_\star \lesssim 0.2 M_\odot$ may not receive enough photons in the photosynthetically active range of $400$-$750$ nm to sustain Earth-like biospheres.
