Study of exoplanets is one of the main goals of present research in planetary sciences and astrobiology. Analysis of huge planetary data from space missions such as CoRoT and Kepler is directed ultimately at finding a planet similar to Earth—the Earth’s twin, and answering the question of potential exo-habitability. The Earth Similarity Index (ESI) is a first step in this quest, ranging from 1 (Earth) to 0 (totally dissimilar to Earth). It was defined for the four physical parameters of a… 

Indexing Exoplanets with Physical Conditions Potentially Suitable for Rock-Dependent Extremophiles

This paper examined rocky exoplanets whose physical conditions are potentially suitable for the survival of rock-dependent extremophiles, such as the cyanobacteria Chroococcidiopsis and the lichen Acarospora.

Tardigrade indexing approach on exoplanets.

Quantitative indexing and tardigrade analysis of exoplanets

Search of life elsewhere in the galaxy is very fascinating area for planetary scientists and astrobiologists. Earth Similarity Index (ESI) is defined as geometrical mean of four physical parameters

Extremophile life-form survey on rocky exoplanets

Search for different life-forms elsewhere is the fascinating area of research in astrophysics and astrobiology. Nearly 3500 exoplanets are discovered according to NASA exoplanet archive database.

Quantifying the classification of exoplanets: in search for the right habitability metric

What is habitability? Can we quantify it? What do we mean under the term habitable or potentially habitable planet? With estimates of the number of planets in our Galaxy alone running into billions,

Advanced aspects of Galactic habitability

The aim is to numerically investigate the dynamics of opposed processes of expansion and extinction of life in the Galaxy using a new type of numerical simulation based on 1D probabilistic cellular automaton with very high temporal resolution.

Habitability Models for Planetary Sciences

Habitability has been generally defined as the capability of an environment to support life. Ecologists have been using Habitat Suitability Models (HSMs) for more than four decades to study the

Habitability Models for Astrobiology.

The different models used by ecologists and astrobiologists are reviewed and how they could be integrated into new habitability standards will help improve the comparison and characterization of potentially habitable environments, prioritize target selections, and study correlations between habitability and biosignatures.



A two-tiered approach to assessing the habitability of exoplanets.

A two-tiered classification scheme of exoplanet habitability and a Planetary Habitability Index (PHI), designed to minimize the biased search for life as the authors know it and to take into account life that might exist under more exotic conditions.


Exoplanet habitability is traditionally assessed by comparing a planet’s semimajor axis to the location of its host star’s “habitable zone,” the shell around a star for which Earth-like planets can

The Search for Habitable Worlds. 1. The Viability of a Starshade Mission

As part of NASA’s mission to explore habitable planets orbiting nearby stars, this article explores the detection and characterization capabilities of a 4 m space telescope plus 50 m starshade

Anthropic selection and the habitability of planets orbiting M and K dwarfs

Two Earth-sized planets orbiting Kepler-20

A statistical method is applied to show that the likelihood of the planetary interpretation of the transit signals is more than three orders of magnitude larger than that of the alternative hypothesis that the signals result from an eclipsing binary star.

Age aspects of habitability

Abstract A ‘habitable zone’ of a star is defined as a range of orbits within which a rocky planet can support liquid water on its surface. The most intriguing question driving the search for

The mass of the Mars-sized exoplanet Kepler-138 b from transit timing

The sizes and masses of three planets orbiting Kepler-138, a star much fainter and cooler than the Sun, are reported, determining that the mass of the Mars-sized inner planet, Kepler- 138 b, is Earth masses and its density is grams per cubic centimetre.
