100%, Zurich, fixed-term
SPECULOOS (Search for habitable Planets EClipsing ULtra-cOOl Stars) is an international, ground-based exoplanet survey that utilizes a network of small, fully robotic telescopes to identify Earth-sized planets transiting nearby ultra-cool dwarf stars. The small radii of these stars present exceptional opportunities for the detection and detailed characterization of rocky exoplanets.
The southern SPECULOOS observatory (SSO) at Paranal is being outfitted with a new dual-band imaging system, DUET, engineered to facilitate simultaneous visible and near-infrared observations of the same target. This capability will allow for the detection of small planetary transit signals, even when masked 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 integral to the installation, commissioning, and early scientific exploitation of the DUET system. The scientific focus of the project centers on harnessing simultaneous visible and infrared observations to enhance the precision of transit parameters while disentangling stellar and atmospheric variability from planetary signals. This role will involve developing advanced techniques for 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. The PhD project will offer invaluable hands-on experience with astronomical instrumentation and state-of-the-art data analysis within a world-leading research environment at ETH Zürich. This work directly supports the preparation and characterization of prime targets for atmospheric studies with the James Webb Space Telescope, with the wider aim of advancing the understanding of potentially habitable Earth analogues around nearby low-mass stars.
During the PhD, the student will develop expertise in:
The PhD position (100%) is anticipated to commence in September 2026 (or to be agreed upon with the successful candidate). The initial appointment will last four years, contingent on satisfactory progress, in accordance with ETH Zürich doctoral regulations.
The PhD position is fully funded and based at ETH Zürich. The successful candidate will be employed as a doctoral researcher at ETH Zürich under Swiss employment conditions, receiving salary and social benefits based on ETH Zürich and Swiss federal regulations.
