The Stellar Observations Network Group (SONG) -- A Legacy Archive of Stellar Time-Domain Spectroscopy

M. N. Lund, F. Grundahl, M. S. Fredslund +41

The Stellar Observations Network Group (SONG) network has operated for more than a decade, providing long-baseline, high-cadence spectroscopic observations of bright stars and the…

HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT

Laura Magrini, Thomas Bensby, Sofia Randich +174

This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…

Asteroseismology of the G8 subgiant beta Aquilae with SONG-Tenerife, SONG-Australia and TESS

Hans Kjeldsen, Timothy R. Bedding, Yaguang Li +28

We present time-series radial velocities of the G8 subgiant star beta Aql obtained in 2022 and 2023 using SONG-Tenerife and, for the first time, SONG-Australia. We also analyse a s…

Calibrations of Atmospheric Parameters Obtained from the First Year of SDSS-III APOGEE Observations

Sz. Mészáros, J. Holtzman, A. E. García Pérez +25

The SDSS-III Apache Point Observatory Galactic Evolution Experiment (APOGEE) is a three year survey that is collecting 100,000 high-resolution spectra in the near-IR across multipl…

The Asymptotic Giant Branches of GCs: Selective Entry Only

S. W. Campbell, V. D'Orazi, T. N. Constantino +7

The handful of available observations of AGB stars in Galactic Globular Clusters suggest that the GC AGB populations are dominated by cyanogen-weak stars. This contrasts strongly w…

Cyanogen in NGC 1851 RGB and AGB Stars: Quadrimodal Distributions

S. W. Campbell, D. Yong, E. C. Wylie-de Boer +7

The Galactic globular cluster NGC 1851 has raised much interest since HST photometry revealed that it hosts a double subgiant branch. Here we report on our homogeneous study into t…

The Ninth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-III Baryon Oscillation Spectroscopic Survey

III Collaboration, Christopher P. Ahn, Rachael Alexandroff +224

The Sloan Digital Sky Survey III (SDSS-III) presents the first spectroscopic data from the Baryon Oscillation Spectroscopic Survey (BOSS). This ninth data release (DR9) of the SDSS…

Two views of globular cluster stars in the Galactic halo

Sarah L. Martell

In Martell & Grebel (2010) we reported the discovery in the Sloan Digital Sky Survey-II/SEGUE spectroscopic database of a small subset of halo red giants, 2.5%, with CN and CH band…

Building the Galactic halo from globular clusters: evidence from chemically unusual red giants

Sarah L. Martell, Jason P. Smolinski, Timothy C. Beers +1

We present a spectroscopic search for halo field stars that originally formed in globular clusters. Using moderate-resolution SDSS-III/SEGUE-2 spectra of 561 red giants with typica…
