    Predicting Stellar Parameters of Massive Stars from Light Curves with Machine Learning
    High-resolution spectroscopic measurements of OB stars are important for understanding processes like stellar evolution but require labor-intensive observations...

    Pristine stars in the Milky-Way and beyond
    To understand the early phases of galaxy formation, metal-poor stars in the local universe play a special rôle, allowing to trace both how galactic assembly...

    Probing 3D and NLTE models using APOGEE observations of globular cluster stars
    Context. Hydrodynamical (or 3D) and non-local thermodynamic equilibrium (NLTE) effects are known to affect abundance analyses. However, there are very few...

    Probing IGM large-scale flows: warps in galaxies at shells of voids
    Context: Hydrodynamical cosmological simulations predict flows of the intergalactic medium along the radial vector of the voids, approximately in the direction...

    Probing Thin Winds in Massive OB Stars of the SMC with JWST/NIRSPEC Brα Spectroscopy
    Mass loss is a key physical process in the evolution of massive stars, the impact of which propagates into galactic evolution, population synthesis models, the...

    Prolate rotation and metallicity gradient in the transforming dwarf galaxy Phoenix
    Transition type dwarf galaxies are thought to be systems undergoing the process of transformation from a star-forming into a passively evolving dwarf, which...

    Proper Motions and Orbits of Distant Local Group Dwarf Galaxies from a Combination of Gaia and Hubble Data
    We have determined the proper motions (PMs) of 12 dwarf galaxies in the Local Group (LG), ranging from the outer Milky Way (MW) halo to the edge of the LG. We...

    Proper Motions of Local Group Dwarf Spheroidal Galaxies I: First Ground-Based Results for Fornax
    In this article we present in detail the methodology and the first results of a ground-based program to determine the absolute proper motion of the Fornax dwarf...
