The Origin of Elements Across Cosmic Time: Astro2020 Science White Paper

Jennifer A. Johnson, Gail Zasowski, David Weinberg +14

The problem of the origin of the elements is a fundamental one in astronomy and one that has many open questions. Prominent examples include (1) the nature of Type Ia supernovae an…

Are the double-mode bulge RR Lyrae stars with identical period-ratios the relic of a disrupted stellar system?

Andrea Kunder, Alex Tilton, Dylon Maertens +6

Radial velocities of fifteen double-mode bulge RR Lyrae (RR01) stars are presented, six of which belong to a compact group of RR01 stars in pulsation space, with the ratio of first…

The K2-HERMES Survey: Age and Metallicity of the Thick Disc

Sanjib Sharma, Dennis Stello, Joss Bland-Hawthorn +34

Asteroseismology is a promising tool to study Galactic structure and evolution because it can probe the ages of stars. Earlier attempts comparing seismic data from the {\it Kepler}…

The Scientific Context of WFIRST Microlensing in the 2020s

Jennifer Yee, Rachel Akeson, Jay Anderson +23

[abridged] WFIRST is uniquely capable of finding planets with masses as small as Mars at separations comparable to Jupiter, i.e., beyond the current ice lines of their stars. These…

Wide-Orbit Exoplanet Demographics

David P. Bennett, Rachel Akeson, Yann Alibert +41

The Kepler, K2 and TESS transit surveys are revolutionizing our understanding of planets orbiting close to their host stars and our understanding of exoplanet systems in general, b…

Discovery of a nitrogen-enhanced mildly metal-poor binary system: Possible evidence for pollution from an extinct AGB Star

José G. Fernández-Trincado, Ronald Mennickent, Mauricio Cabezas +13

We report the serendipitous discovery of a nitrogen-rich, mildly metal-poor ([Fe/H]=-1.08) giant star in a single-lined spectroscopic binary system found in the SDSS-IV Apache Poin…
