Planets and the Possibility of Life beyond Earth 

Zygon
The question of whether life exists beyond Earth has intrigued humans throughout history. Millennia of speculation have fueled both philosophy and theology, with contemplations of the spiritual state of alien beings shedding new light on that state of ...

Assessing the Possibility of Biological Complexity on Other Worlds, with an Estimate of the Occurrence of Complex Life in the Milky Way Galaxy

Challenges, 2014
Rational speculation about biological evolution on other worlds is one of the outstanding challenges in astrobiology. With the growing confirmation that multiplanetary systems abound in the universe, the prospect that life occurs redundantly throughout ...

ExoPhot: The Photon Absorption Rate as a New Metric for Quantifying the Exoplanetary Photosynthetic Activity Fitness

Universe, 2022
Only a low percentage of the radiation from our Sun is captured by photosynthesis, but this conversion of solar to chemical energy sustains all life on Earth.

The EChO science case [PDF]

, 2015
The discovery of almost two thousand exoplanets has revealed an unexpectedly diverse planet population. We see gas giants in few-day orbits, whole multi-planet systems within the orbit of Mercury, and new populations of planets with masses between that ...

Shaping of Planetary Nebulae by Exoplanets

Galaxies, 2020
(1) Background: We investigate the hypothesis that exoplanet engulfment can help explain the observed non-spherical planetary nebula population, as a complementary shaping mechanism to the binary hypothesis.

Doppler-Shifted Alkali D Absorption as Indirect Evidence for Exomoons

Frontiers in Astronomy and Space Sciences, 2022
Sodium and potassium signatures in transiting exoplanets can be challenging to isolate from the stellar absorption lines. Here, these challenges are discussed in the framework of Solar System observations, and transits of Mercury in particular. Radiation

OGLE 2008–BLG–290 : an accurate measurement of the limb darkening of a galactic bulge K giant spatially resolved by microlensing [PDF]

, 2010
Context. Not only is gravitational microlensing a successful tool for discovering distant exoplanets, but it also enables characterization of the lens and source stars involved in the lensing event. Aims.

Exoplanets in science fiction [PDF]

Science fiction (SF) is a genre influenced by science which, in turn, influences science. Astronomers discovered the first exoplanets (planets outside our solar system) in the 1990s, but exoplanets featured in SF long before then.
