abstract

We present here SPECULOOS, a new exoplanet transit search based on a network of 1m-class robotic telescopes targeting the $\sim$1200 ultracool (spectral type M7 and later) dwarfs bright enough in the infrared ($K$-mag $\leq 12.5$) to possibly enable the atmospheric characterization of temperate terrestrial planets with next-generation facilities like the $\textit{James Webb Space Telescope}$. The ultimate goals of the project are to reveal the frequency of temperate terrestrial planets around the lowest-mass stars and brown dwarfs, to probe the diversity of their bulk compositions, atmospheres and surface conditions, and to assess their potential habitability.

Discussion (0). Continue with ORCID to comment.

  1. JWST sighting of decameter main-belt asteroids and view on meteorite sources

    astro-ph.EP 2025-02 conditional novelty 7.0 of 10

    Serendipitous JWST/MIRI observations reveal 139 decameter main-belt asteroids, the smallest population sample ever seen there, with a size-frequency break near 100 meters.

  2. Cataclysmic variables from SRG/eROSITA: new systems from eRASS1

    astro-ph.SR 2026-07 accept novelty 6.0 of 10

    A Random Forest plus Gaia/eROSITA match yields 156 spectroscopically confirmed CVs from eRASS1, spanning subtypes, periods, and luminosities, with the method outperforming several published alternatives.

  3. ASTEP confirmation of a pair of long-period Jupiter-sized planets with extremely low densities transiting TOI-791

    astro-ph.EP 2026-06 unverdicted novelty 5.0 of 10

    Two extremely low-density Jupiter-sized planets on long-period orbits around TOI-791 were confirmed via ground-based photometry and TTV-derived masses.

  4. TOI-2015b: a sub-Neptune in strong gravitational interaction with an outer non-transiting planet

    astro-ph.EP 2025-02 conditional novelty 5.0 of 10

    TOI-2015 hosts a 3.35-day transiting sub-Neptune with about 9.2 Earth masses and 3.31 Earth radii, plus an outer non-transiting companion near a 5:3 orbital resonance.

  5. Configuration of the $\xi$ Tau system constrained by multi-technique observations

    astro-ph.SR 2026-05 unverdicted novelty 4.0 of 10

    Multi-technique observations constrain the configuration of the ξ Tau system, detecting orbital oscillations on multiple timescales and suggesting component C is itself a binary.

  6. TOI-2407 b: a warm Neptune in the desert

    astro-ph.EP 2025-06 conditional novelty 4.0 of 10

    TOI-2407 b is a validated warm Neptune with radius 4.26 Earth radii on a 2.7-day orbit around an M2 star, sitting in the period-radius Neptune desert.
