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…
Astrometry and Precise Radial Velocities Yield a Complete Orbital Solution for the Nearby Eccentric Brown Dwarf LHS 1610 b
Evan Fitzmaurice, Gudmundur Stefánsson, Robert D. Kavanagh +18
The LHS 1610 system consists of a nearby ( pc) M5 dwarf hosting a candidate brown dwarf companion in a day, eccentric () orbit. We confirm this brown dwa…
DI Herculis Revisited: Starspots, Gravity Darkening, and 3-D Obliquities
Yan Liang, Joshua N. Winn, Simon H. Albrecht
DI Herculis is an eclipsing binary famous for a longstanding disagreement between theory and observation of the apsidal precession rate, which was resolved when both stars were fou…
Precise radial velocities of giant stars XV. Mysterious nearly periodic radial velocity variations in the eccentric binary Cygni
Paul Heeren, Sabine Reffert, Trifon Trifonov +10
Using the Hamilton Echelle Spectrograph at Lick Observatory, we have obtained precise radial velocities (RVs) of a sample of 373 G- and K-giant stars over more than 12 years, leadi…
First Results From The Hertzsprung Song Telescope: Asteroseismology Of The G5 Subgiant Star {\Mu}Her
F. Grundahl, M. Fredslund Andersen, J. Christensen-Dalsgaard +26
We report the first asteroseismic results obtained with the Hertzsprung SONG Telescope from an extensive high-precision radial-velocity observing campaign of the subgiant muHerculi…
