Automation and Modernisation of Legacy BiSON Solar Observatories with the BiSON:NG Platform

S. J. Hale, E. Murray, W. J. Chaplin +4

The Birmingham Solar Oscillations Network (BiSON) provides long-term, high-precision Sun-as-a-star radial-velocity observations for helioseismology. While most BiSON sites operate…

ROOSTER: a machine-learning analysis tool for Kepler stellar rotation periods

Sylvain N. Breton, Angela R. G. Santos, Lisa Bugnet +3

In order to understand stellar evolution, it is crucial to efficiently determine stellar surface rotation periods. An efficient tool to automatically determine reliable rotation pe…

Properties of the Hyades, the eclipsing binary HD27130, and the oscillating red giant Tau

K. Brogaard, E. Pakštienė, F. Grundahl +21

Eclipsing binary stars allow derivation of accurate and precise masses and radii. When they reside in star clusters, properties of even higher precision, along with additional info…

Sun-like Oscillations in the Population II giant HD 122563

Orlagh Creevey, Frédéric Thévenin, Frank Grundahl +8

We have been monitoring the metal-poor Population II giant, HD 122563, for radial velocity variations since 2016 using the SONG telescope on Tenerife. We have detected the global s…

Acoustic oscillations and dynamo action in the G8 sub-giant EK Eri

A. Bonanno, E. Corsaro, F. Del Sordo +3

We present further evidence of the presence of acoustic oscillations on the slowly-rotating, over-active G8 sub-giant EK Eri. This star was observed with the 1-m Hertzsprung SONG t…

Oscillations in the Sun with SONG: Setting the scale for asteroseismic investigations

M. Fredslund Andersen, P. Pallé, J. Jessen-Hansen +12

Context. We present the first high-cadence multi-wavelength radial-velocity observations of the Sun-as-a-star, carried out during 57 consecutive days using the stellar échelle spec…
