Analysis of accretion disc structure and stability using open code for vertical structure
Detailed chemical abundances of very metal-poor (VMP; [Fe/H] < -2) stars are important for better understanding the first stars, early star formation, and chemical enrichment of galaxies. Big on-going and coming high-resolution spectroscopic surveys provid ...
OXFORD UNIV PRESS2023Design of the third-generation lead-based neutron spallation target for the neutron time-of-flight facility at CERN
Roland Logé, Nicola Colonna, Raffaele Esposito
The neutron time-of-flight (n_TOF) facility at the European Laboratory for Particle Physics (CERN) is a pulsed white-spectrum neutron spallation source producing neutrons for two experimental areas: the Experimental Area 1 (EAR1), located 185 m horizontall ...
AMER PHYSICAL SOC2021The formation of the milky way halo and its dwarf satellites: a NLTE-1D abundance analysis. IV. Segue 1, Triangulumii, and Coma Berenices UFDs
We present atmospheric parameters and abundances for chemical elements from carbon to barium in metal-poor stars in Segue 1 (seven stars), Coma Berenices (three stars), and Triangulum II (one star) ultrafaint dwarf galaxies (UFDs). The effective temperatur ...
OXFORD UNIV PRESS2021The Pristine survey - XIV. Chemical analysis of two ultra-metal-poor stars
Pascale Jablonka, Carmela Lardo
Elemental abundances of the most metal-poor stars reflect the conditions in the early Galaxy and the properties of the first stars. We present a spectroscopic follow-up of two ultra-metal-poor stars ([Fe/H] < -4.0) identified by the survey Pristine: Pristi ...
OXFORD UNIV PRESS2021The chemical evolution of the dwarf spheroidal galaxy Sextans
Pascale Jablonka, Pierre North, Carmela Lardo, Romain Ely Roland Lucchesi, Romaine Theler
We present our analysis of the FLAMES dataset targeting the central 25 ' region of the Sextans dwarf spheroidal galaxy (dSph). This dataset is the third major part of the high-resolution spectroscopic section of the ESO large program 171.B-0588(A) obtained ...
