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 ...

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.

Habitability of Super-Earths: Gliese 581c and 581d
, 2008 The unexpected diversity of exoplanets includes a growing number of super-Earth planets, i.e., exoplanets with masses smaller than 10 Earth masses. Unlike the larger exoplanets previously found, these smaller planets are more likely to have a similar ...

Evolution of Exoplanets and their Parent Stars [PDF]
, 2013 Studying exoplanets with their parent stars is crucial to understand their population, formation and history. We review some of the key questions regarding their evolution with particular emphasis on giant gaseous exoplanets orbiting close to solar-type ...

Habitable Zones in Binary Star Systems: A Zoology
Galaxies, 2020 Several concepts have been brought forward to determine where terrestrial planets are likely to remain habitable in multi-stellar environments. Isophote-based habitable zones, for instance, rely on insolation geometry to predict habitability, whereas ...

The Power of a Name: Toward a Unified Approach to Naming Space Weather Events
Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.Abstract Our increasing reliance on technology vulnerable to space weather effects underscores the urgent need for effective public communication about these phenomena. While scientific research thrives on precise technical language, broader public engagement necessitates a more accessible and memorable approach.

The WASP-South search for transiting exoplanets
EPJ Web of Conferences, 2011 Since 2006 WASP-South has been scanning the Southern sky for transiting exoplanets. Combined with Geneva Observatory radial velocities we have so far found over 30 transiting exoplanets around relatively bright stars of magnitude 9–13.

The Habitability of the Galactic Bulge
Life, 2020 We present a new investigation of the habitability of the Milky Way bulge, that expands previous studies on the Galactic Habitable Zone. We discuss existing knowledge on the abundance of planets in the bulge, metallicity and the possible frequency of ...

Comparing Geochemical and Geodynamical Models of Plume and Ridge Mantle Source Composition
Geochemistry, Geophysics, Geosystems, Volume 26, Issue 8, August 2025.Abstract We use a multidisciplinary approach to investigate how the parameter space of mantle convection affects present‐day mantle composition. We compare 22 forward geodynamical mantle circulation model simulations against 24 variants of a geochemical inversion model of the global radiogenic isotope data set of mantle‐derived lavas.

On homogeneous statistical distributions exoplanets for their dynamic parameters
, 2009 Correct distributions of extrasolar systems for their orbital parameters (semi-major axes, period, eccentricity) and physical characteristics (mass, spectral type of parent star) are received. Orbital resonances in extrasolar systems are considered.
