Validation of the ESPRESSO Wavelength Calibration Using Iodine Absorption Cell Spectra

Tobias M. Schmidt, Ansgar Reiners, Michael T. Murphy +3

High quality wavelength calibration is crucial for science cases like radial-velocity studies of exoplanets, the search for a possible variation of fundamental constants, and the r…

At least one in a dozen stars exhibits evidence of planetary ingestion

Fan Liu, Yuan-Sen Ting, David Yong +6

Stellar chemical compositions can be altered by ingestion of planetary material and/or planet formation which removes refractory material from the proto-stellar disc. These "planet…

A New Precise Determination of the Primordial Abundance of Deuterium: Measurement in the metal-poor sub-DLA system at z=3.42 towards quasar J1332+0052

P. A. Kislitsyn, S. A. Balashev, M. T. Murphy +3

The theory of Big Bang nucleosynthesis, coupled with an estimate of the primordial deuterium abundance (D/H)_pr, offers insights into the baryon density of the Universe. Independen…

C3PO: Towards a complete census of co-moving pairs of stars. I. High precision stellar parameters for 250 stars

David Yong, Fan Liu, Yuan-Sen Ting +6

We conduct a line-by-line differential analysis of a sample of 125 co-moving pairs of stars (dwarfs and subgiants near solar metallicity). We obtain high precision stellar paramete…
