SPECULOOS (Search for habitable Planets EClipsing ULtra-cOOl Stars) is an international, ground-based exoplanet survey utilizing a network of small, fully robotic telescopes to detect Earth-sized planets transiting nearby ultra-cool dwarf stars. The small radii of these stars present exceptional opportunities for identifying and characterizing rocky exoplanets.
The southern SPECULOOS observatory (SSO) at Paranal is being enhanced with a new dual-band imaging system, DUET, which will enable simultaneous visible and near-infrared observations of the same target. This capability allows for the detection of small planetary transit signals that may otherwise be obscured by stellar variability in low-mass stars and brown dwarfs. The DUET system is set to begin 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 early scientific exploitation of the DUET system. The primary scientific focus will leverage simultaneous visible and infrared observations to enhance the precision of transit parameters and disentangle stellar and atmospheric variability from planetary signals. This will necessitate 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 will provide practical experience with astronomical instrumentation and state-of-the-art data analysis in a leading research environment at ETH Zürich. The work directly contributes to the preparation and characterization of prime targets for atmospheric studies with the James Webb Space Telescope, with the broader aim of advancing the study of potentially habitable Earth analogs around nearby low-mass stars.
During the PhD, the student will develop expertise in:
The PhD position (100%) is expected to commence in September 2026 (or as agreed with the successful candidate). The initial appointment will be for four years, contingent on satisfactory progress in accordance with ETH Zürich doctoral regulations.
