  • Chemical abundances and Doppler imaging of the Ap Si/He-wk star HD 100357
    We present the results of time-resolved photometry, abundance analysis, and Doppler imaging of an Ap star, HD 100357. The TESS photometry revealed rotational modulation with a period of 1.6279247 d. Upon inspecting the residuals after removing the rotational period and its harmonics, we found additional frequencies around 15.8054 d $^{-1}$, which

  • Caveats about measuring carbon abundances in stars using the CH band
    Context. Stellar carbon abundances are crucial for tracing the star formation history and predicting the near-infrared emission of galaxies. It is still a complex task to derive accurate carbon abundance estimates for a wide variety of stars because it is hard to measure it based on atomic and molecular lines. It therefore remains challenging to

  • 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

  • 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
