Defining the Circumstellar Habitable Zone [PDF]

, 2015
The study of habitable exoplanets is a rapidly expanding field in astronomy. Exoplanets are planets that orbit stars other than our own sun. One of the keys to knowing whether or not an exoplanet is habitable is by studying the circumstellar habitable ...

Probing the limits of habitability: a catalogue of rocky exoplanets in the habitable zone

Monthly Notices of the Royal Astronomical Society
ABSTRACT While most of the 6000 discovered exoplanets are highly unlike the Earth, the first rocky worlds in the habitable zone (HZ) provide intriguing targets for the search for life in the cosmos. As detections increase, it is critical to test the empirical HZ as well as its limits using known exoplanets. However, there is not yet a

Kepler-62:a five-planet system with planets of 1.4 and 1.6 Earth radii in the habitable zone

, 2013
We present the detection of five planets - Kepler-62b, c, d, e, and f - of size 1.31, 0.54, 1.95, 1.61 and 1.41 Earth radii (R⊕), orbiting a K2V star at periods of 5.7, 12.4, 18.2, 122.4, and 267.3 days, respectively.

Leaving children behind for cross‐border education: Unveiling the emotional agency of international post‐graduate student mothers

British Educational Research Journal, EarlyView.
Abstract Despite growing interest in the internationalisation of higher education, the experiences of international student parents, particularly international student mothers, remain largely marginalised in research and policy. This paper examines the emotional agency of international student mothers who leave their children behind in their home ...

Rebuilding the Habitable Zone from the Bottom up with Computational Zones

Astrobiology
Computation, if treated as a set of physical processes that act on information represented by states of matter, encompasses biological systems, digital systems, and other constructs and may be a fundamental measure of living systems. The opportunity for biological computation, represented in the propagation and selection-driven evolution of information-

Biographies, ontological security and the socio‐spatial politics shaping teachers' mobility in remote Australia

British Educational Research Journal, EarlyView.
Abstract The global teacher shortage continues to intensify, with disparate impacts across geographic and socio‐economic communities. In Queensland, Australia, where this study originates, post‐COVID teacher shortages have intensified workforce pressures, leaving several regional, rural and remote schools as some of the ‘hardest‐to‐staff’ in the ...

Discoveries and Other Information in Physics and Astronomy of the Last Decade, which Have a Potential to Influence our View on the Universe

Communications, 2017
In the last decade, natural sciences (sometimes called exact sciences) have nearly every week brought some discoveries or important news, which have consequences on our understanding of the world and the whole Universe, its past and future, and which may
