Wind Power as a Technosignature on M-dwarf Planets

Jacob Haqq-Misra, Mykhaylo Danylov

We suggest that the large-scale deployment of wind turbines on an M-dwarf planet could produce observable technosignatures. Motivated by observations of hypersonic wind velocities…

Galactic settlement of low-mass stars as a resolution to the Fermi paradox

Jacob Haqq-Misra, Thomas J. Fauchez

An expanding civilization could rapidly spread through the galaxy, so the absence of extraterrestrial settlement in the solar system implies that such expansionist civilizations do…

Population Growth, Energy Use, and the Implications for the Search for Extraterrestrial Intelligence

Brendan Mullan, Jacob Haqq-Misra

Von Hoerner (1975) examined the effects of human population growth and predicted agricultural, environmental, and other problems from observed growth rate trends. Using straightfor…

The Drake Equation as a Function of Spectral Type and Time

Jacob Haqq-Misra, Ravi Kumar Kopparapu

This chapter draws upon astronomical observations and modeling to constrain the prevalence of communicative civilizations in the galaxy. We discuss the dependence of the Drake equa…

Why do we find ourselves around a yellow star instead of a red star?

Jacob Haqq-Misra, Ravi Kumar Kopparpu, Eric T. Wolf

M-dwarf stars are more abundant than G-dwarf stars, so our position as observers on a planet orbiting a G-dwarf raises questions about the suitability of other stellar types for su…

Funding the Search for Extraterrestrial Intelligence with a Lottery Bond

Jacob Haqq-Misra

I propose the establishment of a SETI Lottery Bond to provide a continued source of funding for the search for extraterrestrial intelligence (SETI). The SETI Lottery Bond is a fixe…

On the likelihood of non-terrestrial artifacts in the Solar System

Jacob Haqq-Misra, Ravi Kumar Kopparapu

Extraterrestrial technology may exist in the Solar System without our knowledge. This is because the vastness of space, combined with our limited searches to date, implies that any…

A Protocol for Messaging to Extraterrestrial Intelligence

Dimitra Atri, Julia DeMarines, Jacob Haqq-Misra

Messaging to extraterrestrial intelligence (METI) is a branch of study concerned with constructing and broadcasting a message toward habitable planets. Since the Arecibo message of…
