    An investigation of non-canonical mixing in red giant stars using APOGEE <SUP>12</SUP>C/<SUP>13</SUP>C ratios observed in open cluster stars
    Standard stellar evolution theory poorly predicts the surface abundances of chemical species in low-mass, red giant branch (RGB) stars. Observations show an...

    An ionized superbubble powered by a protocluster at z = 6.5
    We show herein that a proto-cluster of Ly α emitting galaxies, spectroscopically confirmed at redshift 6.5, produces a remarkable number of ionizing continuum...

    An M dwarf accompanied by a close-in giant orbiter with SPECULOOS
    In the last decade, a dozen close-in giant planets have been discovered orbiting stars with spectral types ranging from M0 to M4, a mystery since known...

    An old, metal-poor globular cluster in Sextans A and the metallicity floor of globular cluster systems
    We report the confirmation of an old, metal-poor globular cluster (GC) in the nearby dwarf irregular galaxy Sextans A, the first GC known in this galaxy. The...

    An optical transmission spectrum of the giant planet WASP-36 b
    We present broad-band photometry of five transits in the planetary system WASP-36, totalling 17 high-precision light curves. Four of the transits were...

    An optimized Hβ index for disentangling stellar population ages
    We have defined a new Hβ absorption index definition, Hβo, which has been optimized as an age indicator for old and intermediate age stellar populations. Rather...

    An ultraviolet spectral study of fullerene-rich planetary nebulae
    Several planetary nebulae (PNe) have been found to contain both polycyclic aromatic hydrocarbon (PAH-like) species and fullerenes (C 60) distinguished by their...

    An unusual transient in the extremely metal-poor Galaxy SDSS J094332.35+332657.6 (Leoncino Dwarf)
    We have serendipitously discovered that Leoncino Dwarf, an ultrafaint, low-metallicity record-holder dwarf galaxy, may have hosted a transient source, and...

    An XMM-Newton observation of the neutron star X-ray transient 2S 1803-245 in quiescence
    We observed the neutron star X-ray transient 2S 1803-245 in quiescence with the X-ray satellite XMM-Newton, but did not detect it. An analysis of the X-ray...
