The Carbon-Dependent Binary Frequency of CEMP-no Stars
John D. Dixon, Terese T. Hansen, Jennifer Marshall +15
The authors monitored radial velocities of 30 CEMP-no stars and combined these data with literature to assess binary frequencies, finding that high‑carbon CEMP-no stars have a sign…
Boötes III is a Tidally Disrupting Ultra-Faint Dwarf Galaxy on an Eccentric Polar Orbit
Ting S. Li, Denis Erkal, Andrew B. Pace +20
We present updated systemic properties of the ultra-faint dwarf galaxy Boötes III from the Southern Stellar Stream Spectroscopic Survey (S). We identify 21 high-probability me…
Investigating non-LTE abundances of Neodymium (Nd) in metal-poor FGK stars
John D. Dixon, Rana Ezzeddine, Yangyang Li +3
The dominant site(s) of the -process are a subject of current debate. Ejecta from -process enrichment events like kilonovae are difficult to directly measure, so we must inst…
Ground-Based Reconnaissance Observations of 21 Exoplanet Atmospheres with the Exoplanet Transmission Spectroscopy Imager
Ryan J. Oelkers, Luke M. Schmidt, Erika Cook +24
One of the most prolific methods of studying exoplanet atmospheres is transmission spectroscopy, which measures the difference between the depth of an exoplanet's transit signal at…
