Seth Gossage is a Research Associate at the Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) at Northwestern University, where he was promoted from CIERA postdoc in 2024 after three years (2021-2024). He collaborates extensively with Professor Vicky Kalogera on stellar evolution modeling and population synthesis.
His research focuses on stellar evolution, particularly through computational modeling using MESA and development of the POSYDON population synthesis code. Key interests include:
- Effects of stellar rotation on observational signatures
- Binary star evolution pathways
- Convective dynamics in low-mass stars
- Progenitor systems for supernovae and gravitational wave sources
Analysis of his 15 most recent publications (2023-2025) reveals a strong emphasis on binary interactions across metallicity ranges, with significant contributions to understanding stripped-envelope supernovae, double neutron star formation, and gamma-ray burst progenitors. His work bridges theoretical modeling with observational constraints from HST and spectroscopic surveys.
Notable scientific contributions include:
- First-author paper on convective turnover times in low-mass stars (ApJ 2025)
- Key role in POSYDON v2 development for cosmological metallicity ranges
- Analysis of Be star-black hole binaries using LAMOST data
Gossage mentors through CIERA's REU program (evidenced by student presentations at AAS meetings) and contributes to outreach initiatives. His current work involves developing grids of 1D stellar models to replicate population data while investigating rotational effects.
