Identical or fraternal twins? : The chemical homogeneity of wide binaries from Gaia DR2
Keith Hawkins, Madeline Lucey, Yuan-Sen Ting +7
One of the high-level goals of Galactic archaeology is chemical tagging of stars across the Milky Way to piece together its assembly history. For this to work, stars born together…
Know thy star, know thy planet: Chemo-kinematically characterizing TESS targets
Andreia Carrillo, Keith Hawkins, Brendan P. Bowler +2
The Transiting Exoplanet Survey Satellite (TESS) has already begun to discover what will ultimately be thousands of exoplanets around nearby cool bright stars. These potential host…
Astro2020 APC White Paper: The Early Career Perspective on the Coming Decade, Astrophysics Career Paths, and the Decadal Survey Process
Emily Moravec, Ian Czekala, Kate Follette +53
In response to the need for the Astro2020 Decadal Survey to explicitly engage early career astronomers, the National Academies of Sciences, Engineering, and Medicine hosted the Ear…
The Kepler Smear Campaign: Light curves for 102 Very Bright Stars
Benjamin J. S. Pope, Guy R. Davies, Keith Hawkins +19
We present the first data release of the Kepler Smear Campaign, using collateral 'smear' data obtained in the Kepler four-year mission to reconstruct light curves of 102 stars too…
Testing asteroseismology with Gaia DR2: Hierarchical models of the Red Clump
Oliver J. Hall, Guy R. Davies, Yvonne P. Elsworth +8
Asteroseismology provides fundamental stellar parameters independent of distance, but subject to systematics under calibration. Gaia DR2 has provided parallaxes for a billion stars…
4MOST: Project overview and information for the First Call for Proposals
R. S. de Jong, O. Agertz, A. Agudo Berbel +335
We introduce the 4-metre Multi-Object Spectroscopic Telescope (4MOST), a new high-multiplex, wide-field spectroscopic survey facility under development for the four-metre-class Vis…
Ages and kinematics of chemically selected, accreted Milky Way halo stars
Payel Das, Keith Hawkins, Paula Jofre
We exploit the [Mg/Mn]-[Al/Fe] chemical abundance plane to help identify nearby halo stars in the 14th data release from the APOGEE survey that have been accreted on to the Milky W…
The COMBS survey I: Chemical Origins of Metal-Poor Stars in the Galactic Bulge
Madeline Lucey, Keith Hawkins, Melissa Ness +7
Chemistry and kinematic studies can determine the origins of stellar population across the Milky Way. The metallicity distribution function of the bulge indicates that it comprises…
Constraining Metallicity-dependent Mixing and Extra Mixing using [C/N] in Alpha-Rich Field Giants
Matthew Shetrone, Jamie Tayar, Jennifer A. Johnson +11
Internal mixing on the giant branch is an important process which affects the evolution of stars and the chemical evolution of the galaxy. While several mechanisms have been propos…
The Lazy Giants: APOGEE Abundances Reveal Low Star Formation Efficiencies in the Magellanic Clouds
David L. Nidever, Sten Hasselquist, Christian R. Hayes +28
We report the first APOGEE metallicities and alpha-element abundances measured for 3600 red giant stars spanning a large radial range of both the Large (LMC) and Small Magellanic C…
