The influence of general-relativity effects, dynamical tides and collisions on planet-planet scattering close to the star

open access: yes, 2019
Planet--Planet scattering is an efficient and robust dynamical mechanism for producing eccentric exoplanets. Coupled to tidal interactions with the central star, it can also explain close--in giant planets on circularized and potentially misaligned ...

Exoplanet Clouds [PDF]

open access: yesAnnual Review of Earth and Planetary Sciences, 2019
Clouds, which are common features in Earth's atmosphere, form in atmospheres of planets that orbit other stars than our Sun, in so-called extrasolar planets or exoplanets. Exoplanet atmospheres can be chemically extremely rich. Exoplanet clouds are therefore composed of a mix of materials that changes throughout the atmosphere.

Interdisciplinary Communication: From Gravitational Waves to Multiuniverses [PDF]

open access: yesJournal of Systemics, Cybernetics and Informatics, 2020
The prospect of communication with other universes utilizing High-Frequency Gravitational Waves (HFGWs) is discussed. Global communications via HFGWs were analyzed by us in 2012 [1]. We extended communications involved in that paper to intercommunication

Habitability of Super-Earths: Gliese 581c and 581d

open access: yes, 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 ...

Imaging and Characterization of Extrasolar Planets with the Next Generation of Space Telescopes

open access: yesGeosciences, 2018
The study and characterization of the exoplanets’ atmospheres and composition is in its infancy. The large facilities that will make feasible to image an exo-Earth are currently under study.

Exoplanet Terra Incognita

open access: yes, 2018
Exoplanet surface imaging, cartography and the search for exolife are the next frontiers of planetology and astrophysics. Here we present an over-view of ideas and techniques to resolve albedo features on exoplanetary surfaces.

The Adaptability of Life on Earth and the Diversity of Planetary Habitats

open access: yesFrontiers in Microbiology, 2017
The evolutionary adaptability of life to extreme environments is astounding given that all life on Earth is based on the same fundamental biochemistry. The range of some physicochemical parameters on Earth exceeds the ability of life to adapt, but stays ...

Is Life an Unavoidable Consequence of the Formation of the Universe? Investigating the Formation of Bio-Precursors and the Signature of Earth-Like Living Forms

open access: yesFrontiers in Astronomy and Space Sciences, 2018
This contribution to the Research Topic “Imagining the Future of Astronomy and Space Sciences” focuses on astrobiology and exoplanetary research. Understanding the origin of life is the main scientific challenge to this century and an interdisciplinary ...
