The size of the Milky Way galaxy
Jianhui Lian, Gail Zasowski, Bingqiu Chen +4
The size of a galaxy is one of the fundamental parameters that reflects its growth and assembly history. Traditionally, the size of the Milky Way has been characterized by the scal…
The wave-like disk oscillations of mono-age stellar populations in the Solar neighbourhood from Gaia DR3
Tao Wang, Bing-Qiu Chen, Jian-Hui Lian +2
The North-South asymmetry in the number density and bulk velocity of stars in the solar neighborhood provides valuable insights into the formation and evolution of the Milky Way di…
Disk Assembly of the Milky Way Suggested from the Time-resolved Chemical Abundance
Enci Wang, Jianhui Lian, Yingjie Peng +1
Both simulations and observations suggest that the disk assembly of galaxies is governed by the interplay between coplanar gas inflow, ex-planar gas outflow and in-situ star format…
The Extremely Metal Rich Knot of Stars at the Heart of the Galaxy
Hans-Walter Rix, Vedant Chandra, Gail Zasowski +15
We show with Gaia XP spectroscopy that extremely metal-rich stars in the Milky Way (EMR; ) - but only those - are largely confined to a tight "knot" at the center…
Observational constraints on the origin of the elements. VIII. Constraining the Barium, Strontium and Yttrium chemical evolution in metal-poor stars
G. Guiglion, M. Bergemann, N. Storm +3
Recently Lian et al. (2023), thanks to Gaia-ESO data, studied the chemical evolution of neutron-capture elements in the regime [Fe/H]>-1. We aim here to complement this study down…
Observational constraints on the origin of the elements. VI. Origin and evolution of neutron-capture elements as probed by the Gaia-ESO survey
Jianhui Lian, Nicholas Storm, Guillaume Guiglion +5
Most heavy elements beyond the iron peak are synthesized via neutron capture processes. The nature of the astrophysical sites of neutron capture processes is still very unclear. In…
