Interstellar communication. VI. Searching X-ray spectra for narrowband communication
Michael Hippke, Duncan H. Forgan
We have previously argued that targeted interstellar communication has a physical optimum at narrowband X-ray wavelengths nm, limited by the surface roughness of focus…
Interstellar communication. III. Optimal frequency to maximize data rate
Michael Hippke, Duncan H. Forgan
The optimal frequency for interstellar communication, using "Earth 2017" technology, was derived in papers I and II of this series (arXiv:1706.03795, arXiv:1706.05570). The framewo…
Towards a population synthesis model of self-gravitating disc fragmentation and tidal downsizing II: The effect of fragment-fragment interactions
D. H. Forgan, C. Hall, F. Meru +1
It is likely that most protostellar systems undergo a brief phase where the protostellar disc is self-gravitating. If these discs are prone to fragmentation, then they are able to…
Photogravimagnetic assists of light sails: a mixed blessing for Breakthrough Starshot?
Duncan H. Forgan, René Heller, Michael Hippke
Upon entering a star system, light sails are subject to both gravitational forces and radiation pressure, and can use both in concert to modify their trajectory. Moreover, stars po…
Can planet formation resolve the dust budget crisis in high redshift galaxies?
D. H. Forgan, K. Rowlands, H. L. Gomez +4
The process of planet formation offers a rich source of dust production via grain growth in protostellar discs, and via grinding of larger bodies in debris disc systems. Chemical e…
The chemistry of protoplanetary fragments formed via gravitational instabilities
J. D. Ilee, D. H. Forgan, M. G. Evans +8
In this paper, we model the chemical evolution of a 0.25 M protoplanetary disc surrounding a 1 M star that undergoes fragmentation due to self-gravity. We use S…
