The Galactic Phosphorus Survey. I. Chemical Evolution across the Galactic Disk from 750 FGK Stars
Dionysios Gakis, Keith Hawkins, Zachary G. Maas +5
Phosphorus (P) is an odd- element produced primarily in massive stars and is also important for planetary chemistry as an element essential to life. However, its evolution over…
Toward Reliable Interpretations of Small Exoplanet Compositions: Comparisons and Considerations of Equations of State and Materials Used in Common Rocky Planet Models
Joseph Schulze, Natalie Hinkel, Wendy Panero +1
The bulk compositions of small planets () are directly linked to their formation histories, making reliable compositional constraints imperative for testi…
Database Design for SpExoDisks: A Database & Web Portal for Spectra of Exoplanet-Forming Disks
Caleb Wheeler, Natalie R. Hinkel, Andrea Banzatti
Data access -- or the availability of new and archival data for use by the larger community -- is key for scientific advancement. How data is presented, searched, and formatted det…
High-resolution Elemental Abundance Measurements of Cool JWST Planet Hosts Using AutoSpecFit: An Application to the Sub-Neptune K2-18b's Host M dwarf
Neda Hejazi, Ian J. M. Crossfield, Diogo Souto +9
We present an in-depth, high-resolution spectroscopic analysis of the M dwarf K2-18 that hosts a sub-Neptune exoplanet in its habitable zone. We show our technique to accurately no…
