The MiMeS Survey of Magnetism in Massive Stars: Introduction and overview
G. A. Wade, C. Neiner, E. Alecian +47
The MiMeS project is a large-scale, high resolution, sensitive spectropolarimetric investigation of the magnetic properties of O and early B type stars. Initiated in 2008 and compl…
The astrometric Gaia-FUN-SSO observation campaign of 99 942 Apophis
W. Thuillot, D. Bancelin, A. Ivantsov +71
Astrometric observations performed by the Gaia Follow-Up Network for Solar System Objects (Gaia-FUN-SSO) play a key role in ensuring that moving objects first detected by ESA's Gai…
Orbit determination of Transneptunian objects and Centaurs for the prediction of stellar occultations
J. Desmars, J. I. B. Camargo, F. Braga-Ribas +10
The prediction of stellar occultations by Transneptunian objects and Centaurs is a difficult challenge that requires accuracy both in the occulted star position as for the object e…
Consistent metallicity scale for cool dwarfs and giants. A benchmark test using the Hyades
Letícia Dutra-Ferreira, Luca Pasquini, Rodolfo Smiljanic +2
In several instances chemical abundances of dwarf and giant stars are used simultaneously under the assumption that they share the same abundance scale. This assumption might have…
A morpho-kinematic and spectroscopic study of the bipolar nebulae: M 2-9, Mz 3, and Hen 2-104
Niall Clyne, Stavros Akras, Wolfgang Steffen +3
Context. Complex bipolar shapes can be generated either as a planetary nebula or a symbiotic system. The origin of the material ionised by the white dwarf is very different in thes…
The Apache Point Observatory Galactic Evolution Experiment (APOGEE)
Steven R. Majewski, Ricardo P. Schiavon, Peter M. Frinchaboy +75
The Apache Point Observatory Galactic Evolution Experiment (APOGEE), one of the programs in the Sloan Digital Sky Survey III (SDSS-III), has now completed its systematic, homogeneo…
