Ripples of Stellar Enrichment (RoSE) - simulating element production and mixing in a Milky Way-mass galactic disc star-by-star
Chuhan Zhang, Mark R. Krumholz, Melissa K. Ness +3
We present the Ripples of Stellar Enrichment (RoSE) simulations, which follow an isolated Milky Way-mass disc galaxy with star-by-star feedback and nucleosynthesis from five physic…
A Galactic Perspective on the (Unremarkable) Relative Refractory Depletion Observed in the Sun
Rayna Rampalli, James W. Johnson, Melissa K. Ness +5
Over the last two decades, the Sun has been observed to be depleted in refractory elements as a function of elemental condensation temperature (\tcond) relative to of it…
Optical Spectroscopy Reveals Hidden Neutron-capture Elemental Abundance Differences among APOGEE-identified Chemical Doppelgängers
Catherine Manea, Melissa Ness, Keith Hawkins +9
Grouping stars by chemical similarity has the potential to reveal the Milky Way's evolutionary history. The APOGEE stellar spectroscopic survey has the resolution and sensitivity f…
Disentangling Metallicity Effects in Hot Jupiter Occurrence Across Galactic Birth Radius and Phase-Space Density
Rayna Rampalli, Melissa K. Ness, Elisabeth R. Newton +3
We explore how the correlation between host star metallicity and giant planets shapes hot Jupiter occurrence as a function of Galactic birth radius (\rbirth) and phase-space densit…
A Data-driven Spectral Model of Main Sequence Stars in Gaia DR3
Isabel Angelo, Megan Bedell, Erik Petigura +1
Precise spectroscopic classification of planet hosts is an important tool of exoplanet research at both the population and individual system level. In the era of large-scale survey…
The Sun Remains Relatively Refractory Depleted: Elemental Abundances for 17,412 Gaia RVS Solar Analogs and 50 Planet Hosts
Rayna Rampalli, Melissa K. Ness, Graham H. Edwards +2
The elemental abundances of stars, particularly the refractory elements (e.g., Fe, Si, Mg), play an important role in connecting stars to their planets. Most Sun-like stars do not…
