About
A. H. M. J. Triaud is a prominent exoplanet astronomer whose research centers on the detection and characterization of terrestrial planets orbiting ultracool dwarf stars, with a particular focus on building the infrastructure needed to find potentially habitable worlds. Triaud is a leading figure in the SPECULOOS project (Search for Habitable Planets EClipsing ULtra-cOOl Stars), a sophisticated network of robotic 1-meter telescopes designed to survey roughly 1,200 of the nearest ultracool dwarfs — stars small and cool enough that transiting Earth-sized planets could realistically have their atmospheres probed by next-generation observatories like the James Webb Space Telescope. His foundational papers establishing SPECULOOS's scientific rationale, target strategy, and observatory performance have collectively garnered over 270 citations, reflecting the community's enthusiasm for this approach. Beyond planet hunting, Triaud has contributed to brown dwarf science, notably documenting rapidly evolving atmospheric weather patterns on WISE J104915.57-531906.1, the third-closest system to the Sun. He has also contributed to the WASP-South transit survey, broadening his expertise across multiple exoplanet detection programs. Together, his body of work represents a sustained, infrastructure-driven effort to answer one of astronomy's most compelling questions: are temperate, rocky planets common around the smallest stars?
