    Investigating Phosphorus Abundances in a Sample of APOGEE-2 Bulge Globular Clusters
    Phosphorus-enhanced (P-rich; [P/Fe] ≳ +0.8) giants have been found among mildly metal-poor field stars, but in only one star in a globular cluster (GC), M4 (NGC...

    Ionization correction factors for sodium, potassium, and calcium in planetary nebulae
    We use a large grid of photoionization models that are representative of observed planetary nebulae (PNe) to derive ionization correction factors (ICFs) for...

    Ionized gas diagnostics from protoplanetary discs in the Orion nebula and the abundance discrepancy problem
    We present results from integral field spectroscopy of a field located near the Trapezium Cluster using the Potsdam Multi-Aperture Spectrophotometer (PMAS). The...

    Ionized gas in the XUV disc of the NGC 1512/1510 system
    We present deep, intermediate-resolution, optical spectroscopy of 136 genuine UV-bright regions located in both the inner and outer regions of NGC 1512. This...

    IRAS 17423-1755 (Hen 3-1475) Revisited: An O-rich High-mass Post-asymptotic Giant Branch Star
    The high-resolution (R ~ 600) Spitzer/IRS spectrum of the bipolar protoplanetary nebula (PN) IRAS 17423-1755 is presented in order to clarify the dominant...

    Iron and s-elements abundance variations in NGC 5286: comparison with `anomalous' globular clusters and Milky Way satellites
    We present a high-resolution spectroscopic analysis of 62 red giants in the Milky Way globular cluster (GC) NGC 5286. We have determined abundances of...

    Is macroturbulent broadening in OB Supergiants related to pulsations?
    The spectrum of O and B Supergiants is known to be affected by an important extra line-broadening (usually called macroturbulence) that adds to stellar rotation...

    Is Terzan 5 the remnant of a building block of the Galactic bulge? Evidence from APOGEE
    It has been proposed that the globular cluster-like system Terzan 5 is the surviving remnant of a primordial building block of the Milky Way bulge, mainly due...

    J-PLUS: Identification of low-metallicity stars with artificial neural networks using SPHINX
    Context. We present a new methodology for the estimation of stellar atmospheric parameters from narrow- and intermediate-band photometry of the Javalambre...
