Lessons learnt from the Solar neighbourhood and the Kepler field
Luca Casagrande
Setting the timeline of the events which shaped the Milky Way disc through its 13 billion year old history is one of the major challenges in the theory of galaxy formation. Achievi…
Globular and Open Clusters Observed by SDSS/SEGUE: the Giant Stars
Heather L. Morrison, Zhibo Ma, James L. Clem +10
We present griz observations for the clusters M92, M13 and NGC 6791 and gr photometry for M71, Be 29 and NGC 7789. In addition we present new membership identifications for all the…
Interstellar Extinction Curve Variations Toward the Inner Milky Way: A Challenge to Observational Cosmology
David M. Nataf, Oscar A. Gonzalez, Luca Casagrande +18
We investigate interstellar extinction curve variations toward 4 deg of the inner Milky Way in photometry from the OGLE-III and surveys, with supportin…
Oscillating red giants observed during Campaign 1 of the Kepler K2 mission: New prospects for galactic archaeology
D. Stello, D. Huber, S. Sharma +21
NASA's re-purposed Kepler mission -- dubbed K2 -- has brought new scientific opportunities that were not anticipated for the original Kepler mission. One science goal that makes op…
The dissimilar chemical composition of the planet-hosting stars of the XO-2 binary system
I. Ramirez, S. Khanal, P. Aleo +7
Using high-quality spectra of the twin stars in the XO-2 binary system, we have detected significant differences in the chemical composition of their photospheres. The differences…
The GALAH Survey: Scientific Motivation
G. M. De Silva, K. C. Freeman, J. Bland-Hawthorn +44
The GALAH survey is a large high-resolution spectroscopic survey using the newly commissioned HERMES spectrograph on the Anglo-Australian Telescope. The HERMES spectrograph provide…
