  • Advancing the accuracy in age determinations of old-disk stars using an oscillating red giant in an eclipsing binary
    Context. The study of resonant oscillation modes in low-mass red giant branch stars enables us to infer their ages with exceptional (∼10%) precision. This unlocks the possibility to reconstruct the temporal evolution of the Milky Way at early cosmic times. Ensuring the accuracy of such a precise age scale is a fundamental but difficult challenge

  • A Gravitational-wave-detectable Candidate Type Ia Supernova Progenitor
    Type Ia supernovae (SNe Ia), critical for studying cosmic expansion, arise from thermonuclear explosions of white dwarfs, but their precise progenitor pathways remain unclear. Growing evidence supports the "double-degenerate scenario," where two white dwarfs interact. The absence of nondegenerate companions capable of explaining the observed SN Ia

  • A Dark, Bare Rock for TOI-1685 b from a JWST NIRSpec G395H Phase Curve
    We report JWST NIRSpec/G395H observations of TOI-1685 b, a hot rocky super-Earth orbiting an M2.5V star, during a full orbit. We obtain transmission and emission spectra of the planet and characterize the properties of the phase curve, including its amplitude and offset. The transmission spectrum rules out clear H 2-dominated atmospheres, while

  • A Comparative Study of the Ground State Transitions of CO and C I as Molecular Gas Tracers at High Redshift
    The CO(1–0) and [C I](1–0) emission lines are well-established tracers of cold molecular gas mass in local galaxies. At high redshift, where the interstellar medium is likely to be denser, there have been limited direct comparisons of both ground-state transitions. We present a comparison of [C I](1–0) and CO(1–0) emission in 20 unlensed dusty

  • Year six photometric measurements of known Trans-Neptunian Objects and Centaurs by the Dark Energy Survey
    We identified known Trans-Neptunian Objects (TNOs) and Centaurs in the complete Dark Energy Survey (DES) year six catalogue (DES Y6) through the Sky Body Tracker (SkyBoT) tool. We classified our data set of 144 objects into a widely used 4-class taxonomic system of TNOs. No such previous classification was available in the literature for most of

  • Wide Binary Orbits Are Preferentially Aligned with the Orbits of Small Planets, but Probably Not Hot Jupiters
    Studying the relative orientations of the orbits of exoplanets and wide-orbiting binary companions (semimajor axis greater than 100 au) can shed light on how planets form and evolve in binary systems. Previous observations by multiple groups discovered a possible alignment between the orbits of visual binaries and the exoplanets that reside in them
