A homogeneous analysis of globular clusters from the APOGEE survey with the BACCHUS code. I. The Northern clusters
T. Masseron, D. A. García-Hernández, Sz. Mészáros +12
We analyze a large sample of 885 GCs giants from the APOGEE survey. We used the Cannon results to separate the red giant branch and the asymptotic giant branch stars, not only allo…
The Mira-based distance to the Galactic centre
Wenzer Qin, David M. Nataf, Nadia Zakamska +2
Mira variables are useful distance indicators, due to their high luminosities and well-defined period-luminosity relation. We select 1863 Miras from SAAO and MACHO observations to…
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…
The GALAH and TESS-HERMES surveys: high-resolution spectroscopy of luminous supergiants in the Magellanic Clouds and Bridge
Jeffrey D. Simpson, Dennis Stello, Sanjib Sharma +24
We report the serendipitous observations of 571 luminous supergiants in the Magellanic Clouds by the spectroscopic GALAH and TESS-HERMES surveys: 434 stars in the Large Magellanic…
The GALAH Survey: Second Data Release
S. Buder, M. Asplund, L. Duong +39
The Galactic Archaeology with HERMES (GALAH) survey is a large-scale stellar spectroscopic survey of the Milky Way and designed to deliver chemical information complementary to a l…
Holistic spectroscopy: Complete reconstruction of a wide-field, multi-object spectroscopic image using a photonic comb
Janez Kos, Joss Bland-Hawthorn, Christopher H. Betters +18
The primary goal of Galactic archaeology is to learn about the origin of the Milky Way from the detailed chemistry and kinematics of millions of stars. Wide-field multi-fibre spect…
The GALAH Survey: Stellar streams and how stellar velocity distributions vary with Galactic longitude, hemisphere and metallicity
Alice C. Quillen, Gayandhi De Silva, Sanjib Sharma +30
Using GALAH survey data of nearby stars, we look at how structure in the planar (u,v) velocity distribution depends on metallicity and on viewing direction within the Galaxy. In ne…
The GALAH Survey: Velocity fluctuations in the Milky Way using red clump giants
Shourya Khanna, Sanjib Sharma, Joss Bland-Hawthorn +20
If the Galaxy is axisymmetric and in dynamical equilibrium, we expect negligible fluctuations in the residual line-of-sight velocity field. Recent results using the \apg{} survey f…
The GALAH Survey: Verifying abundance trends in the open cluster M67 using non-LTE spectroscopy
Xudong Gao, Karin Lind, Anish M. Amarsi +28
Open cluster members are coeval and share the same initial bulk chemical compositions. Consequently, differences in surface abundances between members of a cluster that are at diff…
The GALAH Survey: Accurate Radial Velocities and Library of Observed Stellar Template Spectra
Tomaž Zwitter, Janez Kos, Andrea Chiavassa +34
GALAH is a large-scale magnitude-limited southern stellar spectroscopic survey. Its second data release (GALAH DR2) provides values of stellar parameters and abundances of 23 eleme…
The GALAH survey: Co-orbiting stars and chemical tagging
Jeffrey D. Simpson, Sarah L. Martell, Gary Da Costa +24
We present a study using the second data release of the GALAH survey of stellar parameters and elemental abundances of 15 pairs of stars identified by Oh et al 2017. They identifie…
The GALAH survey: An abundance, age, and kinematic inventory of the solar neighbourhood made with TGAS
S. Buder, K. Lind, M. K. Ness +31
The overlap between the spectroscopic Galactic Archaeology with HERMES (GALAH) survey & provides a high-dimensional chemodynamical space of unprecedented size. We present a…
UKIRT-2017-BLG-001Lb: A giant planet detected through the dust
Y. Shvartzvald, S. Calchi Novati, B. S. Gaudi +8
We report the discovery of a giant planet in event UKIRT-2017-BLG-001, detected by the UKIRT microlensing survey. The mass ratio between the planet and its host is $q=1.50_{-0.14}^…
The WFIRST Exoplanet Microlensing Survey
David P. Bennett, Rachel Akeson, Jay Anderson +71
The Wide Field Infrared Survey Telescope (WFIRST) was the top ranked large space mission in the 2010 New Worlds, New Horizons decadal survey, and it was formed by merging the scien…
White Paper: Exoplanetary Microlensing from the Ground in the 2020s
Jennifer C. Yee, Jay Anderson, Rachel Akeson +25
Microlensing can access planet populations that no other method can probe: cold wide-orbit planets beyond the snow line, planets in both the Galactic bulge and disk, and free float…
The GALAH survey: properties of the Galactic disk(s) in the solar neighbourhood
L. Duong, K. C. Freeman, M. Asplund +26
Using data from the GALAH pilot survey, we determine properties of the Galactic thin and thick disks near the solar neighbourhood. The data cover a small range of Galactocentric ra…
Radial velocities of RR Lyrae stars in and around NGC 6441
Andrea Kunder, Arthur Mills, Joseph Edgecomb +9
Detailed elemental abundance patterns of metal-poor ([Fe/H] ~ -1~dex) stars in the Galactic bulge indicate that a number of them are consistent with globular cluster (GC) stars and…
