The GALAH Survey: Improving our understanding of confirmed and candidate planetary systems with large stellar surveys

Jake T. Clark, Duncan J. Wright, Robert A. Wittenmyer +24

Pioneering photometric, astrometric, and spectroscopic surveys are helping exoplanetary scientists better constrain the fundamental properties of stars within our galaxy, and the p…

: The Orbital and Chemical Properties of One Dozen Stellar Streams

Ting S. Li, Alexander P. Ji, Andrew B. Pace +19

We report the kinematic, orbital, and chemical properties of 12 stellar streams with no evident progenitors, using line-of-sight velocities and metallicities from the Southern Stel…

Signature of a massive rotating metal-poor star imprinted in the Phoenix stellar stream

Andrew R. Casey, Alexander P. Ji, Terese T. Hansen +13

The Phoenix stellar stream has a low intrinsic dispersion in velocity and metallicity that implies the progenitor was probably a low mass globular cluster. In this work we use Mage…

The GALAH Survey: Chemical tagging and chrono-chemodynamics of accreted halo stars with GALAH+ DR3 and eDR3

Sven Buder, Karin Lind, Melissa K. Ness +27

Since the advent of astrometry, it is possible to identify massive accreted systems within the Galaxy through their unique dynamical signatures. One such system, -Saus…

Measuring the Mass of the Large Magellanic Cloud with Stellar Streams Observed by

Nora Shipp, Denis Erkal, Alex Drlica-Wagner +16

Stellar streams are excellent probes of the underlying gravitational potential in which they evolve. In this work, we fit dynamical models to five streams in the Southern Galactic…

Kinematics of Antlia 2 and Crater 2 from The Southern Stellar Stream Spectroscopic Survey (S5)

Alexander P. Ji, Sergey E. Koposov, Ting S. Li +15

We present new spectroscopic observations of the diffuse Milky Way satellite galaxies Antlia 2 and Crater 2, taken as part of the Southern Stellar Stream Spectroscopic Survey (S5).…
