The s-process at Subsolar Metallicity: Insights from High-Resolution Infrared Spectroscopy of Magellanic Cloud Planetary Nebulae

N. C. Sterling, M. G. Stephenson, Harriet L. Dinerstein +8

We present observations of 12 Magellanic Cloud planetary nebulae (PNe) obtained with the high-resolution near-infrared spectrometer IGRINS on Gemini South. In 10 targets we detect…

A Probabilistic Framework for Population Studies of the Solar Neighborhood: Application to SDSS-V and Gaia

Ilija Medan, Keivan G. Stassun, Zachary Way +8

Studies of the Solar Neighborhood require spectroscopic follow-up of stars identified in astrometric surveys to fully characterize their physical properties. The SDSS-V Solar Neigh…

Virial-based extraction of structures in numerical simulations: The vibes tool

Simon Chevalier, Fabien Louvet, Yann Bernard +9

The processes that determine the stellar initial mass function (IMF) and its connection to the core mass function (CMF) are among the major open questions in star formation. The de…

Weakened inspirals -- I: High mass ratio common envelope interactions in RGB stars

Jack Patrick Nibbs, Orsola De Marco, Lionel Siess +2

The common envelope (CE) interaction between an expanding giant star and a compact companion typically leads to a rapid orbital decay, ending in either a merger or the formation of…

Modern tidal interaction models for rapid binary population synthesis: I. Methods

Veome Kapil, Ilya Mandel, Evgeni Grishin +3

In this work, we present an updated prescription of contemporary tidal dissipation theory adapted for rapid binary population synthesis. Our simplified expressions encode the depen…

Planet engulfment in the chemically anomalous HD 129171/HD 129209 pair

Anne Rathsam, Jorge Meléndez, Rodolfo Smiljanic +2

Binary systems composed of stars with similar parameters should have identical chemical composition. However, many chemically anomalous pairs have been found in the literature, suc…
