Collision of Two Stellar Associations in the Nearby Gum Nebula

Alexandra C. Yep, Russel J. White

Based on Gaia DR2 data and new CHIRON radial velocities, we have discovered that two nearby stellar associations UPK 535 (318.08 0.29 pc, Myr, 174 stars) and…

Stars in the Local Galactic Thick Disk and Halo in Gaia EDR3: A catalogue of Half a Million Local Main-sequence Stars with Photometric Metallicities

Bokyoung Kim, Sebastien Lépine

We present a catalogue of 551,214 main-sequence stars in the local ( kpc) Galactic thick disk and halo, based on a search of stars with large proper motions ($μ_{\mathrm{tot…

The Paschen Jump as a Diagnostic of the Diffuse Nebular Continuum Emission in Active Galactic Nuclei

Hengxiao Guo, Aaron J. Barth, Kirk T. Korista +17

Photoionization modeling of active galactic nuclei (AGN) predicts that diffuse continuum (DC) emission from the broad-line region makes a substantial contribution to the total cont…

The Local Stellar Halo is Not Dominated by a Single Radial Merger Event

Thomas Donlon, Heidi Jo Newberg, Bokyoung Kim +1

We use halo dwarf stars with photometrically determined metallicities that are located within 2 kpc of the Sun to identify local halo substructure. The kinematic properties of thes…

Tracking X-ray Outflows with Optical/IR Footprint Lines

Anna Trindade Falcao, S. B. Kraemer, D. M. Crenshaw +5

We use Cloudy photoionisation models to predict the flux profiles for optical/IR emission lines that trace the footprint of X-ray gas, such as [Fe X] 6375A and [Si X] 1.43m. The…

Chemodynamics of metal-poor wide binaries in the Galactic halo: Association with the Sequoia event

Dongwook Lim, Andreas J. Koch-Hansen, Camilla Juul Hansen +4

Recently, an increasing number of wide binaries has been discovered. Their chemical and dynamical properties are studied through extensive surveys and pointed observations. However…
