Virulence as a Model for Interplanetary and Interstellar Colonisation - Parasitism or Mutualism
Jonathan Starling, Duncan Forgan
In the light of current scientific assessments of human-induced climate change, we investigate an experimental model to inform how resource-use strategies may influence interplanet…
Assessing Circumbinary Habitable Zones using Latitudinal Energy Balance Modelling
Duncan Forgan
Previous attempts to describe circumbinary habitable zones have been concerned with the spatial extent of the zone, calculated analytically according to the combined radiation fiel…
Slingshot Dynamics for Self Replicating Probes and the Effect on Exploration Timescales
Arwen Nicholson, Duncan Forgan
Interstellar probes can carry out slingshot manoeuvres around the stars they visit, gaining a boost in velocity by extracting energy from the star's motion around the Galactic Cent…
On the Possibility of Detecting Class A Stellar Engines Using Exoplanet Transit Curves
Duncan H. Forgan
The Class A stellar engine (also known as a Shkadov thruster) is a spherical arc mirror, designed to use the impulse from a star's radiation pressure to generate a thrust force, pe…
The Hunt for Exomoons with Kepler (HEK): III. The First Search for an Exomoon around a Habitable-Zone Planet
David M. Kipping, Duncan Forgan, Joel Hartman +4
Kepler-22b is the first transiting planet to have been detected in the habitable-zone of its host star. At 2.4 Earth radii, Kepler-22b is too large to be considered an Earth-analog…
A Self-Gravitating Disc Around L1527 IRS?
Duncan Forgan, Ken Rice
Recent observations of the Class 0 protostar L1527 IRS have revealed a rotationally supported disc with an outer radius of at least 100 au. Measurements of the integrated flux at 8…
