Abstract The concept of Galactic Habitable Zone (GHZ) was introduced a few years ago as an extension of the much older concept of Circumstellar Habitable Zone. However, the physical processes underlying the former concept are hard to identify and even harder to quantify. That difficulty does not allow us, at present, to draw any significant conclusions about the extent of the GHZ: it may well be that the entire Milky Way disk is suitable for complex life.  


The study of cosmology, galaxy formation, and exoplanets has now advanced to a stage where a cosmic inventory of terrestrial planets (TPs) may be attempted. By coupling semianalytic models of galaxy

A model of habitability within the Milky Way galaxy.

This study has improved on other literature on the GHZ by populating stars on an individual basis and modeling Type II supernova and Type Ia supernova sterilizations by selecting their progenitors from within this preexisting stellar population.

The Habitability of Our Evolving Galaxy

Planets in other universes: habitability constraints on density fluctuations and galactic structure

Motivated by the possibility that different versions of the laws of physics could be realized within other universes, this paper delineates the galactic structure parameters that allow for habitable

Mapping the Probability of Microlensing Detection of Extra-Solar Planets

The growing rate of increase in the number of the discovered extra-solar planets which has consequently raised the enthusiasm to explore the universe in hope of finding earth-like planets has

Habitability on local, Galactic and cosmological scales

The aim of this paper is to underline conditions necessary for the emergence and development of life. They are placed at local planetary scale, at Galactic scale and within the cosmological

Chemical Elements Abundance in the Universe and the Origin of Life

Element synthesis which started with p-p chain has resulted in several specific characteristics including lack of any stable isotope having atomic masses 5 or 8. The carbon to oxygen ratio is fixed

The Search for Extraterrestrial Intelligence in Earth's Solar Transit Zone.

This work explores Earth's transit zone (ETZ), the projection of a band around Earth's ecliptic onto the celestial plane, where observers can detect Earth transits across the Sun, and finds that about 10(5) K and G dwarf stars should reside within the rETZ.

Evolution of galaxy habitability

We combine a semi-analytic model of galaxy evolution with constraints on circumstellar habitable zones and the distribution of terrestrial planets to probe the suitability of galaxies of different

A stochastic process approach of the drake equation parameters

Abstract The number N of detectable (i.e. communicating) extraterrestrial civilizations in the Milky Way galaxy is usually calculated by using the Drake equation. This equation was established in



The Galactic Habitable Zone: Galactic Chemical Evolution

Abstract We propose the concept of a “Galactic Habitable Zone” (GHZ). Analogous to the Circumstellar Habitable Zone (CHZ), the GHZ is that region in the Milky Way where an Earth-like planet can

Catalog of Nearby Exoplanets

We present a catalog of nearby exoplanets. It contains the 172 known low-mass companions with orbits established through radial velocity and transit measurements around stars within 200 pc. We

Exotic Earths: Forming Habitable Worlds with Giant Planet Migration

This simulation of terrestrial planet growth during and after giant planet migration is applied to close-in giant planets thought to form far from their host stars and migrate inward, through the terrestrial planet zone, via torques with a massive gaseous disk.

Galactic Metallicity Gradients Derived from a Sample of OB Stars

The distribution of stellar abundances along the Galactic disk is an important constraint for models of chemical evolution and Galaxy formation. In this study we derive radial gradients of C, N, O,

One of the criteria for the concept of a galactic habitable zone (GHZ) is that the pattern speed of the stars in the GHZ should be close to the pattern speed of the spiral arms. Another criteria is

The stellar metallicity—giant planet connection

The parent stars of the recently announced planetary system candidates are far from typical in terms of their chemical compositions. In this study we report on spectroscopic abundance analyses of v

The Planet-Metallicity Correlation

We have recently carried out spectral synthesis modeling to determine Teff, log g, v sin i, and [Fe/H] for 1040 FGK-type stars on the Keck, Lick, and Anglo-Australian Telescope planet search

Stellar Evolution with Rotation

The existing grids of star models without rotation allow us to already explain a number of properties of massive and WR stars (cf. Maeder and Conti,1994). In particular, the sequences of star

Possible Consequences of Nearby Supernova Explosions for Atmospheric Ozone and Terrestrial Life

Hard x-ray pulses or increased cosmic radiation originating in nearby supernova explosions may be capable of temporarily removing most of the earth's atmospheric ozone cover even when direct
