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 Gaia -ESO Survey: Lithium enrichment histories of the Galactic thick and thin disc
Xiaoting. Fu, D. Romano, A. Bragaglia +32
Lithium abundance in most of the warm metal-poor main sequence stars shows a constant plateau (A(Li)~2.2 dex) and then the upper envelope of the lithium vs. metallicity distributio…
Rediscovering the origins of the stellar halo with chemical tagging
Sarah L Martell
The Galactic halo has a complex assembly history, which can be seen in its wealth of kinematic and chemical substructure. Globular clusters lose stars through tidal interactions wi…
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…
ESO452-SC11: The lowest mass globular cluster with a potential chemical inhomogeneity
Jeffrey D. Simpson, Gayandhi De Silva, Sarah L. Martell +2
We present the largest spectroscopic investigation of one of the faintest and least studied stellar clusters of the Milky Way, ESO452-SC11. Using the Anglo-Australian Telescope AAO…
Carbon-enhanced metal-poor stars in the SDSS-APOGEE database
Collin L. Kielty, Kim A. Venn, Nicholas B. Loewen +5
We identify six new CEMP stars ([C/Fe]>+0.7 and [Fe/H]< -1.8) and another seven likely candidates within the APOGEE database following Data Release 12. These stars have chemical co…
