The Detection and Characterization of Extrasolar Planets

open access: yesChallenges, 2014
We have now confirmed the existence of > 1800 planets orbiting stars other thanthe Sun; known as extrasolar planets or exoplanets. The different methods for detectingsuch planets are sensitive to different regions of parameter space, and so, we are ...

The strength of habit [PDF]

open access: yesHealth Psychology Review, 2015
Despite its presence in the psychological literature for more than one hundred years, the habit concept, the means by which habit serves to control human behaviour in daily life and the means by wh...

Habitable Zone Lifetime of Exoplanets around Main Sequence Stars [PDF]

open access: yes, 2013
Funding: Dean's Scholarship at the University of East Anglia.The potential habitability of newly discovered exoplanets is initially assessed by determining whether their orbits fall within the circumstellar habitable zone of their star.

M Dwarf Planet Habitability [PDF]

open access: yes, 2017
The habitability of M dwarf planets has been debated greatly, as their parent stars possess both beneficial and detrimental qualities for the development of life.

Evolution of novel activation functions in neural network training for astronomy data: habitability classification of exoplanets

open access: yesThe European Physical Journal Special Topics, 2020
Quantification of habitability is a complex task. Previous attempts at measuring habitability are well documented. Classification of exoplanets, on the other hand, is a different approach and depends on quality of training data available in habitable ...

The habitability of the Universe through 13 billion years of cosmic time [PDF]

open access: yes, 2016
The field of astrobiology has made tremendous progress in modelling galactic-scale habitable zones which offer a stable environment for life to form and evolve in complexity.

A Synergic Strategy to Characterize the Habitability Conditions of Exoplanets Hosted by Solar-Type Stars

open access: yesFrontiers in Astronomy and Space Sciences, 2022
We present a new synergic strategy that merges the potential of asteroseismology with solar space weather/climate techniques in order to characterize solar-like stars and their interaction with hosted exoplanets. The method is based on the use of seismic

Atmospheric studies of habitability in the Gliese 581 system

open access: yes, 2011
The M-type star Gliese 581 is orbited by at least one terrestrial planet candidate in the habitable zone, i.e. GL 581 d. Orbital simulations have shown that additional planets inside the habitable zone of GL 581 would be dynamically stable. Recently, two

The Carbonate Geochemistry of Enceladus' Ocean

open access: yesGeophysical Research Letters, 2020
The plume composition at Enceladus contains clues about conditions and processes in the interior. We present new geochemical interpretations of Cassini mass spectrometry data from the plume gas and salt‐rich ice grains.

Habitability of Super-Earth Planets around Other Suns: Models including Red Giant Branch Evolution [PDF]

open access: yes, 2008
The unexpected diversity of exoplanets includes a growing number of super- Earth planets, i.e., exoplanets with masses of up to several Earth masses and a similar chemical and mineralogical composition as Earth. We present a thermal evolution model for a
