Constraints on the abundance of stellar engines in the Milky Way
Manasvi Lingam, Abraham Loeb
Stellar engines are hypothesized megastructures that extract energy from the host star, typically with the purpose of generating thrust and accelerating the stellar system. We expl…
Limitations of Chemical Propulsion for Interstellar Escape from Habitable Zones around Low-Mass Stars
Manasvi Lingam, Abraham Loeb
The habitable zones of low-mass stars are characterized by escape speeds that can be a few times higher than the Earth's orbit around the Sun. Owing to the exponential dependence o…
Relative Likelihood of Success in the Searches for Primitive versus Intelligent Extraterrestrial Life
Manasvi Lingam, Abraham Loeb
We estimate the relative likelihood of success in the searches for primitive versus intelligent life on other planets. Taking into account the larger search volume for detectable a…
Role of stellar physics in regulating the critical steps for life
Manasvi Lingam, Abraham Loeb
We use the critical step model to study the major transitions in evolution on Earth. We find that a total of five steps represents the most plausible estimate, in agreement with pr…
