100%, Zurich, fixed-term
Join the SPECULOOS (Search for habitable Planets EClipsing ULtra-cOOl Stars) project, an international, ground-based exoplanet survey employing a network of small, fully robotic telescopes to detect Earth-sized planets that transit ultra-cool dwarf stars. These stars present unique opportunities for the detection and detailed characterization of rocky exoplanets.
The southern SPECULOOS observatory (SSO) at Paranal is being equipped with a cutting-edge dual-band imaging system, DUET, designed to provide simultaneous visible and near-infrared observations. This innovative capability aims to detect minor planetary transit signals that may be obscured by stellar variability in low-mass stars and brown dwarfs. The DUET system is scheduled for commissioning on two SPECULOOS telescopes in 2027, with one infrared camera already operational at SSO.
The PhD student will be instrumental in the installation, commissioning, and initial scientific exploitation of the DUET system. The focus of the project is to utilize simultaneous visible and infrared observations to enhance the precision of transit parameters and disentangle stellar and atmospheric variability from planetary signals. This will require the development of advanced techniques for the informed processing and joint analysis of time-series data.
The successful candidate will conduct observational programs with the SPECULOOS facility and actively engage in the scientific activities and operations of the international consortium. This PhD project offers hands-on experience with astronomical instrumentation and state-of-the-art data analysis in a world-leading research environment at ETH Zurich. The work will directly contribute to the preparation and characterization of prime targets for atmospheric studies with the James Webb Space Telescope, furthering our understanding of potentially habitable Earth analogues around nearby low-mass stars.
Throughout the PhD, the student will gain expertise in:
The PhD position (100%) is expected to commence in September 2026 (or as agreed with the successful candidate). The initial appointment is for four years, subject to satisfactory progress in accordance with ETH Zurich doctoral regulations.
