SCATTER Common Envelope Formalism for Triples

Rosanne Di Stefano, Amaan Khwaja, Chiaki Kobayashi

Many stars are components of triple-star systems, or of higher-order multiples. In such systems mass transfer is common, and when the transfer is dynamically unstable, a common env…

Using Binary Population Synthesis to Calculate the Yields of Low- and Intermediate-Mass Binary Populations at Low Metallicity

Zara Osborn, Amanda Karakas, Devika Kamath +3

Asymptotic giant branch (AGB) stars are important to chemical evolution at metallicity () as they contribute significantly to the produc…

Potassium abundances in extremely metal poor stars: Implications for nucleosynthesis in the final stages of massive star evolution

M. N. Ishigaki, N. Tominaga, W. Aoki +5

We present a potassium (K) abundance analysis in extremely metal-poor (EMP) stars based on high-resolution () spectra obtained with the High Dispersion Spectrograph on…

The aluminium-26 distribution in a cosmological simulation of a Milky Way-type Galaxy

B. Wehmeyer, C. Kobayashi, A. Yagüe López +1

Context. The 1.8 MeV gamma-rays corresponding to the decay of the radioactive isotope Al-26 (with a half-life of 0.72 Myr) have been observed by the SPI detector on the INTEGRAL sp…

Supernova dust synthesis --- Carbonaceous dust in the very early universe

Gen Chiaki, Takaya Nozawa, Chiaki Kobayashi +1

Recent observations have revealed the spectral feature of carbonaceous grains even in a very distant galaxy. We develop a state-of-the-art dust synthesis code by self-consistently…

Fluorine abundances in CEMP stars at the lowest metallicity: Hints on the nature of the first stars

Aldo Mura-Guzmán, David Yong, Chiaki Kobayashi +6

In the last decade, the available measurements of fluorine abundance have increased significantly, providing additional information on the chemical evolution of our Galaxy and deta…

Core to Cosmic Edge: SIMBA-C's New Take on Abundance Profiles in the Intragroup Medium at z = 0

Aviv Padawer-Blatt, Zhiwei Shao, Renier T. Hough +9

We employ the SIMBA-C cosmological simulation to study the impact of its upgraded chemical enrichment model (Chem5) on the distribution of metals in the intragroup medium (IGrM). W…
