The Immediate, Exemplary, and Fleeting echelle spectroscopy of SN 2023ixf: Monitoring acceleration of slow progenitor circumstellar material, driven by shock interaction
Danielle Dickinson, Dan Milisavljevic, Braden Garretson +12
We present high resolution WIYN/NEID echelle spectroscopy (R ,000) of the supernova (SN) 2023ixf in M101, obtained 1.51 to 18.51 days after explosion over nine epochs. D…

BD+44 493: Chemo-Dynamical Analysis and Constraints on Companion Planetary Masses from WIYN/NEID Spectroscopy
Vinicius M. Placco, Arvind F. Gupta, Felipe Almeida-Fernandes +11
In this work, we present high-resolution (R~100,000), high signal-to-noise (S/N~800) spectroscopic observations for the well-known, bright, extremely metal-poor, carbon-enhanced st…
