The GALAH survey and Gaia DR2: dissecting the stellar disc's phase space by age, action, chemistry and location
Joss Bland-Hawthorn, Sanjib Sharma, Thor Tepper-Garcia +24
We use the second data releases of the ESA Gaia astrometric survey and the high-resolution GALAH spectroscopic survey to analyse the structure of our Galaxy's disc components. With…
Star Cluster Ages in the Gaia Era
Jieun Choi, Charlie Conroy, Yuan-Sen Ting +3
We use the framework developed as part of the MESA Isochrones and Stellar Tracks (MIST) project to assess the utility of several types of observables in jointly measuring the age a…
The GALAH Survey and Gaia DR2: (Non)existence of five sparse high-latitude open clusters
Janez Kos, Gayandhi de Silva, Joss Bland-Hawthorn +21
Sparse open clusters can be found at high galactic latitudes where loosely populated clusters are more easily detected against the lower stellar background. Because most star forma…
The GALAH survey: a catalogue of carbon-enhanced stars and CEMP candidates
Klemen Čotar, Tomaž Zwitter, Janez Kos +19
Swan bands - characteristic molecular absorption features of the C molecule - are a spectroscopic signature of carbon-enhanced stars. They can also be used to identify carbon-e…
Measuring Radial Orbit Migration in the Milky Way Disk
Neige Frankel, Hans-Walter Rix, Yuan-Sen Ting +2
We develop and apply a model to quantify the global efficiency of radial orbit migration among stars in the Milky Way disk. This model parameterizes the possible star formation and…
On the Red Giant Branch: Ambiguity in the Surface Boundary Condition Leads to ~100 K Uncertainty in Model Effective Temperatures
Jieun Choi, Aaron Dotter, Charlie Conroy +1
The effective temperature (Teff) distribution of stellar evolution models along the red giant branch (RGB) is sensitive to a number of parameters including the overall metallicity,…
