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. V. Introduction to photon information efficiency (in bits per photon)
Michael Hippke
How many bits of information can a single photon carry? Intuition says "one", but this is incorrect. With an alphabet based on the photon's time of arrival, energy, and polarizatio…
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…
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…
Interstellar communication. II. Application to the solar gravitational lens
Michael Hippke
We have shown in paper I of this series (arXiv:1706.03795) that interstellar communication to nearby (pc) stars is possible at data rates of bits per second per Watt between a 1 m…
Interstellar communication. I. Maximized data rate for lightweight space-probes
Michael Hippke
Recent technological advances could make interstellar travel possible, using ultra-lightweight sails pushed by lasers or solar photon pressure, at speeds of a few percent the speed…
