The K2-HERMES Survey. I. Planet Candidate Properties from K2 Campaigns 1-3
Robert A. Wittenmyer, Sanjib Sharma, Dennis Stello +31
Accurate and precise radius estimates of transiting exoplanets are critical for understanding their compositions and formation mechanisms. To know the planet, we must know the host…
The GALAH survey: Chemical Tagging of Star Clusters and New Members in the Pleiades
Janez Kos, Joss Bland-Hawthorn, Ken Freeman +25
The technique of chemical tagging uses the elemental abundances of stellar atmospheres to `reconstruct' chemically homogeneous star clusters that have long since dispersed. The GAL…
The TESS-HERMES survey Data Release 1: high-resolution spectroscopy of the TESS southern continuous viewing zone
Sanjib Sharma, Dennis Stello, Sven Buder +22
The Transiting Exoplanet Survey Satellite (TESS) will provide high precision time-series photometry for millions of stars with at least a half-hour cadence. Of particular interest…
Mapping the aberrations of a wide-field spectrograph using a photonic comb
Joss Bland-Hawthorn, Janez Kos, Christopher Betters +4
We demonstrate a new approach to calibrating the spectral-spatial response of a wide-field spectrograph using a fibre etalon comb. Conventional wide-field instruments employed on f…
Spatial structure of several diffuse interstellar band carriers
Janez Kos
Diffuse interstellar bands (DIBs) hold a lot of information about the state and the structure of the ISM. Structure can most directly be observed by extensive spectroscopic surveys…
