LMC Stars and Where to Find Them: Inferring Birth Radii for External Galaxies
Yuxi, Lu, Tobias Buck +5
It is well known that stars move away from their birth location over time via radial migration. This dynamical process makes computing the correct chemical evolution, e.g., metalli…
Potential Impact of the Sagittarius Dwarf Galaxy on the Formation of Young O-rich Stars
Tiancheng Sun, Shaolan Bi, Xunzhou Chen +11
The Milky Way underwent significant transformations in its early history, characterised by violent mergers and satellite galaxy accretion. However, recent observations reveal notab…
In this Day and Age: An Empirical Gyrochronology Relation for Partially and Fully Convective Single Field Stars
Yuxi Lu, Ruth Angus, Daniel Foreman-Mackey +1
Gyrochronology, the field of age-dating stars using mainly their rotation periods and masses, is ideal for inferring the ages of individual main-sequence stars. However, due to the…
Revealing the Chemical Structure of the Magellanic Clouds with APOGEE. III. Abundance Gradients of the Small Magellanic Cloud
Joshua T. Povick, David L. Nidever, Pol Massana +10
We determine radial- and age-abundance gradients of the Small Magellanic Cloud (SMC) using spectra of 2,062 red giant branch (RGB) field stars observed by SDSS-IV / APOGEE-2S. With…
Revealing the Chemical Structure of the Magellanic Clouds with APOGEE. II. Abundance Gradients of the Large Magellanic Cloud
Joshua T. Povick, David L. Nidever, Steven R. Majewski +10
We present the abundance gradients of the Large Magellanic Cloud (LMC) for 25 elemental abundance ratios and their respective temporal evolution as well as age-[X/Fe] trends using…
Chemical Cartography of the Sagittarius Stream with Gaia
Emily C. Cunningham, Jason A. S. Hunt, Adrian M. Price-Whelan +5
The stellar stream connected to the Sagittarius (Sgr) dwarf galaxy is the most massive tidal stream that has been mapped in the Galaxy, and is the dominant contributor to the outer…
An abrupt change in the stellar spin-down law at the fully convective boundary
Yuxi Lu, Victor See, Louis Amard +2
The importance of the existence of a radiative core in generating a solar-like magnetic dynamo is still unclear. Analytic models and magnetohydrodynamic simulations of stars sugges…
The impact of early massive mergers on the chemical evolution of Milky Way-like galaxies: insights from NIHAO-UHD simulations
Tobias Buck, Aura Obreja, Bridget Ratcliffe +4
Recent observations of the Milky Way (MW) found an unexpected steepening of the star-forming gas metallicity gradient around the time of the Gaia-Sausage-Enceladus (GSE) merger eve…
