Constraining cosmic scatter in the Galactic halo through a differential analysis of metal-poor stars
Henrique Reggiani, Jorge Meléndez, Chiaki Kobayashi +2
We present the abundances of Li, Na, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, Zn, Sr, Y, Zr, and Ba in a wide metallicity range ( [Fe/H] ). Using the differen…
Manganese spread in Ursa Minor as a proof of sub-classes of type Ia supernovae
Gabriele Cescutti, Chiaki Kobayashi
Context. Recently, new sub-classes of Type Ia supernovae (SNe Ia) were discovered, including SNe Iax. The suggested progenitors of SNe Iax are relatively massive, possibly hybrid C…
The Chemical Evolution Carousel of Spiral Galaxies: Azimuthal Variations of Oxygen Abundance in NGC1365
I-Ting Ho, Mark Seibert, Sharon E. Meidt +9
The spatial distribution of oxygen in the interstellar medium of galaxies is the key to understanding how efficiently metals that are synthesized in massive stars can be redistribu…
The chemical signature of SNIax in the stars of Ursa minor?
G. Cescutti, C. Kobayashi
Recently, a new class of supernovae Ia was discovered: the supernovae Iax; the increasing sample of these objects share common features as lower maximum-light velocities and typica…
The Metallicity and Elemental Abundance Gradients of Simulated Galaxies, and their Environmental Dependence
Philip Taylor, Chiaki Kobayashi
The internal distribution of heavy elements, in particular the radial metallicity gradient, offers insight into the merging history of galaxies. Using our cosmological, chemodynami…
Star Formation in Simulated Galaxies: Understanding the Transition to Quiescence at M
Philip Taylor, Christoph Federrath, Chiaki Kobayashi
Star formation in galaxies relies on the availability of cold, dense gas, which, in turn, relies on factors internal and external to the galaxies. In order to provide a simple mode…
