The Habitable Exoplanet Observatory (HabEx) Mission Concept Study Final Report
B. Scott Gaudi, Sara Seager, Bertrand Mennesson +183
The Habitable Exoplanet Observatory, or HabEx, has been designed to be the Great Observatory of the 2030s. For the first time in human history, technologies have matured sufficient…
Hubble Space Telescope Near-Ultraviolet Spectroscopy of the Bright CEMP-no Star BD+44 493
Vinicius Placco, Timothy Beers, Ian Roederer +10
We present an elemental-abundance analysis, in the near-ultraviolet (NUV) spectral range, for the extremely metal-poor star BD+44 493, a 9th magnitude sub-giant with [Fe/H] = -3.8…
The Heavy Element Enrichment History of the Universe from Neutron Star Mergers with Habitable Worlds Observatory
Eric Burns, Jennifer Andrews, Robert Szabo +23
Understanding where elements were formed has been a key goal in astrophysics for nearly a century, with answers involving cosmology, stellar burning, and cosmic explosions. Since 1…
Astro2020 Science White Paper: Local Dwarf Galaxy Archaeology
Alexander P. Ji, Rachel Beaton, Sukanya Chakrabarti +8
Nearby dwarf galaxies are local analogues of high-redshift and metal-poor stellar populations. Most of these systems ceased star formation long ago, but they retain signatures of t…
The r-Process in Metal Poor Stars and Black Hole Formation
Richard Boyd, Michael Famiano, Bradley Meyer +3
Nucleosynthesis of heavy nuclei in metal-poor stars is generally thought to occur via the r-process because the r-process is a primary process that would have operated early in the…
