The Fe I 4377 Ã Line as a Solar Faculae Indicator: Insights from Spectral Ratio Analysis
Katlyn L. Hobbs, Christopher A. Watson, Jean C. Costes +21
Faculae are a dominant source of stellar activity noise in radial velocity measurements, yet their low contrast and broad surface distribution make them difficult to track in disc-…

Double Neutron Star Delay Times Across Cosmic Metallicities: The Role of Helium Star Progenitors
Abhishek Chattaraj, Jeff J. Andrews, Max Briel +5
Metallicity can play a significant role in massive binary evolution through its impact on the opacity within stellar interiors and wind-driven mass loss. In this work, we investiga…
