Stellar Metallicities from SkyMapper Photometry II: Precise photometric metallicities of 280,000 giant stars with [Fe/H] in the Milky Way

Anirudh Chiti, Anna Frebel, Mohammad K. Mardini +3

The Milky Way's metal-poor stars are nearby ancient objects that are used to study early chemical evolution and the assembly and structure of the Milky Way. Here we present reliabl…

The Metal-Poor Metallicity Distribution of the Ancient Milky Way

Anirudh Chiti, Mohammad K. Mardini, Anna Frebel +1

We present a low metallicity map of the Milky Way consisting of 111,000 giants with [Fe/H] 0.75, based on public photometry from the second data r…

Metal-poor Stars Observed with the Automated Planet Finder Telescope. III. CEMP-no Stars are the Descendant of Population III Stars

Nour Aldein Almusleh, Ali Taani, Sergen Özdemir +4

In this study, we report a probabilistic insight into the stellar mass and supernovae (SNe) explosion energy of the possible progenitors of five CEMP-no stars. This was done by a d…

Cosmological Insights into the Early Accretion of \textit{r}-Process-Enhanced stars. I. A Comprehensive Chemo-dynamical Analysis of LAMOST J1109+0754

Mohammad K. Mardini, Vinicius M. Placco, Yohai Meiron +10

This study presents a comprehensive chemo-dynamical analysis of LAMOST J1109+0754, a bright (V = 12.8), extremely metal-poor (\abund{Fe}{H} = ) star, with a strong \textit{r…

The R-Process Alliance: The Peculiar Chemical Abundance Pattern of RAVE J183013.5-455510

Vinicius M. Placco, Rafael M. Santucci, Zhen Yuan +14

We report on the spectroscopic analysis of RAVE J183013.5-455510, an extremely metal-poor star, highly enhanced in CNO, and with discernible contributions from the rapid neutron-ca…

Probability Distribution of Magnetic Field Strengths through the Cyclotron Lines in High-Mass X-ray Binaries

Ali Taani, Awni Khasawneh, Mohammad Mardini +2

The study of variation of measured cyclotron lines is of fundamental importance to understand the physics of the accretion process in magnetized neutron star systems. We investigat…
