  • Benchmark brown dwarfs – I. A blue M2 + T5 wide binary and a probable young [M4 + M4] + [T7 + T8] hierarchical quadruple
    Benchmark brown dwarfs in wide binary systems are crucial for characterizing substellar objects and calibrating atmospheric and evolutionary models. However, brown dwarf benchmarks with subsolar metallicity, very cool temperatures, or suitability for dynamical mass measurements are rare, limiting our understanding across the full range of mass, age

  • An Aligned Sub-Neptune Revealed with MAROON-X and a Tendency Toward Alignment for Small Planets
    We present the Rossiter–McLaughlin measurement of the sub-Neptune TOI-1759A b with MAROON-X. A joint analysis with MuSCAT3 photometry and nine additional TESS transits produces a sky-projected obliquity of ∣λ∣ = 4° ± 18°. We also derive a true obliquity of ψ = 24° ± 12° making this planet consistent with full alignment albeit to <1σ. With a period

  • A Pristine-UNIONS view on the Galaxy: Kinematics of the distant spur feature of the Sagittarius stream traced by blue horizontal branch stars
    Context. Providing a detailed picture of the Sagittarius stream offers important constraints on the build-up of the Galactic halo as well as its gravitational potential at large radii. While several attempts have been made to model the structure of the Sagittarius stream, no model has yet been able to match all the features observed for the stream

  • A Descriptive Taxonomic Nomenclature for Intermediate-sized Trans-Neptunian Object Spectra
    Trans-Neptunian objects (TNOs), icy remnants of planet formation orbiting beyond Neptune, comprise a dynamically and compositionally diverse population of >5000 known members. An extensive body of literature focuses on the dynamical structure of the trans-Neptunian region. Less information is available on TNO compositions due to the difficulty

  • Variable stars in Local Group galaxies: VII. New insights into the Leo II dSph
    Aims. Pulsating variable stars are invaluable tracers for reconstructing the star formation history and chemical evolution of their host galaxies. In this work, we explore the variable star population of Leo II, a distant dwarf spheroidal satellite of the Milky Way. Methods. We analyse an extensive dataset of ground-based BVRI time-series

  • TOI-1846 b: a super-Earth in the radius valley orbiting a nearby M dwarf
    We present the discovery and validation of a super-Earth planet orbiting the M dwarf star TOI-1846 (TIC 198385543). The host star ( $K_{\rm mag} = 9.6$) is located 47 pc away and has a radius of $R_\star = 0.41 \pm 0.01$ $\rm \, R_\odot$, a mass of $M_\star = 0.40 \pm 0.02$ $\rm \, M_\odot$ and an effective temperature of $T_{\rm eff} = 3568 \pm 44
