Spectroscopic Binary Detection as Agent-Callable Tools: Detecting 40,000+ Main-Sequence Binary Candidates from SDSS DR19 APOGEE Spectra

Serat M. Saad, Yuan-Sen Ting

Unresolved binaries are common in spectroscopic surveys, and their blended light biases the parameters inferred for them. Methods to detect them exist, but applying one to a new da…

PANTERA. I. Hunting for the Most Metal-Rich Stars in the Solar Neighborhood with High-Resolution Spectroscopy

Serat M. Saad, D. M. Rowan, K. Z. Stanek +4

The paper presents the PANTERA high‑resolution spectroscopic survey of 56 nearby metal‑rich stars, measuring their iron abundances and finding many ultra‑metal‑rich objects while e…

A Bayesian Search for Planet Engulfment Signatures in Solar Analogs

Zimo Cheng, Sharon Xuesong Wang, Fan Liu +11

We present a systematic Bayesian search for chemical fingerprints of planet engulfment in 113 solar twins and analogs with high-precision abundance measurements, 45 of which host k…

Egent: An Autonomous Agent for Equivalent Width Measurement

Yuan-Sen Ting, Serat Mahmud Saad, Fan Liu +1

We present Egent, an autonomous agent that combines classical multi-Voigt profile fitting with large language model (LLM) visual inspection and iterative refinement. The fitting en…

Gravitational Anomaly Measurement in Wide Binaries is Sensitive to Orbital Modeling

Serat M. Saad, Yuan-Sen Ting

Recent work by Chae et al. (2026) reported a gravitational anomaly in 36 wide-binary pairs, finding a gravity boost factor of $γ\equiv G_{\rm eff}/G_{\rm N} \approx 1.60_{-0.14}^{…
