Dynamical Origin of the Vertical Metallicity Gradient of the Milky Way Bulge

open access: yesThe Astrophysical Journal
A vertical metallicity gradient (VMG) in the Milky Way bulge is well-established. Yet, its origin has not been fully understood under the Galactic secular evolution scenario.

Tracing Back a Second-generation Star Stripped from Terzan 5 by the Galactic Bar

open access: yesThe Astrophysical Journal Letters
The Galactic bulge hosts the Milky Way’s oldest stars, possibly coming from disrupted globular clusters (GCs) or the bulge’s primordial building blocks, making these stars witnesses to the Galaxy’s early chemical enrichment.

Effect of Galactic Chemical Evolution on Exoplanet Properties

open access: yesThe Astrophysical Journal Letters
We couple a simplified model for galactic chemical evolution with software that models the condensation of dust in protoplanetary disks and software that models the interior structure of planets, in order to estimate the effects that galactic chemical ...
