Conceptualising quality early childhood education: Learning from young children in Brazil and South Africa through creative and play‐based methods

open access: yesBritish Educational Research Journal, EarlyView., 2023
Abstract Early childhood has increasingly been acknowledged as a vital time for all children. Inclusive and quality education is part of the United Nations Sustainable Development Goals, with the further specification that all children have access to quality pre‐primary education.

Stable habitable zones of single Jovian planet systems [PDF]

open access: yes, 2017
With continued improvement in telescope sensitivity and observational techniques, the search for rocky planets in stellar habitable zones is entering an exciting era.

Hot moons and cool stars

open access: yesEPJ Web of Conferences, 2013
The exquisite photometric precision of the Kepler space telescope now puts the detection of extrasolar moons at the horizon. Here, we firstly review observational and analytical techniques that have recently been proposed to find exomoons.

ON THE HABITABLE ZONES OF CIRCUMBINARY PLANETARY SYSTEMS [PDF]

open access: yesThe Astrophysical Journal, 2012
The effect of the stellar flux on exoplanetary systems is becoming an increasingly important property as more planets are discovered in the Habitable Zone (HZ). The Kepler mission has recently uncovered circumbinary planets with relatively complex HZs due to the combined flux from the binary host stars.

Discovery and validation of Kepler-452b:a 1.6 Rsuper earth exoplanet in the habitable zone of a G2 star [PDF]

open access: yes, 2015
We report on the discovery and validation of Kepler-452b, a transiting planet identified by a search through the 4 years of data collected by NASA's Kepler Mission. This possibly rocky planet orbits its G2 host star every days, the longest orbital period

On the timescale forcing in astrobiology [PDF]

open access: yesSerbian Astronomical Journal, 2007
We investigate the effects of correlated global regulation mechanisms, especially Galactic gamma-ray bursts (GRBs), on the temporal distribution of hypothetical inhabited planets, using simple Monte Carlo numerical experiments.

Planets in habitable zones: [PDF]

open access: yesAstronomy & Astrophysics, 2003
The recently discovered planetary system in the binary GamCep was studied concerning its dynamical evolution. We confirm that the orbital parameters found by the observers are in a stable configuration. The primary aim of this study was to find stable planetary orbits in a habitable region in this system, which consists of a double star (a=21.36 AU ...

Predicting multiple planet stability and habitable zone companions in the TESS era [PDF]

open access: yes, 2019
We present an approach that is able to both rapidly assess the dynamical stability of multiple planet systems, and determine whether an exoplanet system would be capable of hosting a dynamically stable Earth-mass companion in its habitable zone (HZ).

The habitable zone for Earth-like exomoons orbiting Kepler-1625b [PDF]

open access: yes, 2019
The recent announcement of a Neptune-sized exomoon candidate orbiting the Jupiter-sized object Kepler-1625b has forced us to rethink our assumptions regarding both exomoons and their host exoplanets.
