Life at a Stellar Scale - Clues of Stellivores Through Metabolism, Navigation and Propulsion

Watch a 48-minute seminar from the European Astrobiology Institute where Dr. Clément Vidal explores the fascinating hypothesis of stellar-scale life forms called stellivores. Delve into the possibility that certain accreting binary star systems might be living organisms that feed on stars, examining evidence through three main research perspectives. Learn about power density patterns in accreting binaries and their potential interpretation as controlled metabolic processes, discover how millisecond pulsars could serve as a galactic GPS system with remarkable 100-meter accuracy, and explore how spider pulsars might function as operational stellar engines. Examine the scientific framework for distinguishing whether these astronomical phenomena represent simple dissipative structures or complex living systems, supported by current astrophysical data and research published in peer-reviewed journals.
