A Critique of the Spite Plateau, and the Astration of Primordial Lithium
J. E. Norris, D. Yong, A. Frebel +1
We investigate the distribution of the lithium abundances, A(Li), of metal-poor dwarf and subgiant stars within the limits 5500 K < Teff < 6700 K, -6.0 < [Fe/H] < -1.5, and logg >…
Multiple Stellar Populations in Globular Clusters with JWST: a NIRCam view of 47 Tucanae
A. P. Milone, A. F. Marino, A. Dotter +11
We use images collected with the near-infrared camera (NIRCam) on board the James Webb Space Telescope and with the Hubble Space Telescope (HST) to investigate multiple populations…
R-Process elements from magnetorotational hypernovae
D. Yong, C. Kobayashi, G. S. Da Costa +11
Neutron-star mergers were recently confirmed as sites of rapid-neutron-capture (r-process) nucleosynthesis. However, in Galactic chemical evolution models, neutron-star mergers alo…
Spectroscopy and photometry of the least-massive Type-II globular clusters: NGC1261 AND NGC6934
A. F. Marino, A. P. Milone, A. Renzini +10
Recent work has revealed two classes of Globular Clusters (GCs), dubbed Type-I and Type-II. Type-II GCs are characterized by a blue- and a red- red giant branch composed of stars w…
Keck HIRES Spectroscopy of SkyMapper Commissioning Survey Candidate Extremely Metal-Poor Stars
A. F. Marino, G. S. Da Costa, A. R. Casey +11
We present results from the analysis of high-resolution spectra obtained with the Keck HIRES spectrograph for a sample of 17 candidate extremely metal-poor (EMP) stars originally s…
The GALAH Survey: Second Data Release
S. Buder, M. Asplund, L. Duong +39
The Galactic Archaeology with HERMES (GALAH) survey is a large-scale stellar spectroscopic survey of the Milky Way and designed to deliver chemical information complementary to a l…
