Galaxy populations in the Hydra I cluster from the VEGAS survey I. Optical properties of a large sample of dwarf galaxies
Antonio La Marca, Reynier Peletier, Enrichetta Iodice +17
At ~50 Mpc, the Hydra I cluster of galaxies is among the closest cluster in the z=0 Universe, and an ideal environment to study dwarf galaxy properties in a cluster environment. We…
Lithium abundances as a tracer of AGB stars pollution in the globular cluster NGC 6752
J. Schiappacasse-Ulloa, S. Lucatello, M. J. Rain +1
This paper presents the chemical abundance analysis of 217 stars in the metal-poor globular cluster NGC 6752, distributed from the turn-off to the lower red giant branch. Aluminium…
Expanding the time domain of multiple populations: evidences of nitrogen variations in the ~1.5 Gyr old star cluster NGC 1783
M. Cadelano, E. Dalessandro, M. Salaris +5
We present the result of a detailed analysis of HST UV and optical deep images of the massive and young (~1.5 Gyr) stellar cluster NGC 1783 in the Large Magellanic Cloud. This syst…
Oxygen and Aluminum-Magnesium Isotopic Systematics of Presolar Nanospinel Grains from CI Chondrite Orgueil
Nan Liu, Nicolas Dauphas, Sergio Cristallo +2
Presolar oxide grains have been previously divided into several groups (Group 1 to 4) based on their isotopic compositions, which can be tied to several stellar sources. Much of av…
Nature of the ultrarelativistic prompt emission phase of GRB 190114C
R. Moradi, J. A. Rueda, R. Ruffini +7
We address the physical origin of the ultrarelativistic prompt emission (UPE) phase of GRB 190114C observed in the interval 1.9-3.99 s, by the Fermi-GBM in 10 keV-10 MeV . Thanks t…
New Multielement Isotopic Compositions of Presolar SiC Grains: Implications for Their Stellar Origins
Nan Liu, Jens Barosch, Larry R. Nittler +5
We report NanoSIMS Si and Mg-Al isotopic data (and C, N, and Ti isotopic data when available) for 85 submicron- to micron-sized presolar SiC grains from the CM2 Murchison meteorite…
