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…

Farside helioseismology with Sun-as-a-star data: the solar cycle as seen with 7-day-long BiSON timeseries

R. Howe, W. J. Chaplin, Y. P. Elsworth +3

We present results from fitting -mode spectra derived from 7-d segments of Sun-as-a-star helioseismic observations from the Birmingham Solar Oscillations Network covering 32 yr.…

K2 results for "young" -rich stars in the Galaxy

V. Grisoni, C. Chiappini, A. Miglio +11

The origin of apparently young -rich stars in the Galaxy is still a matter of debate in Galactic archaeology, whether they are genuinely young or might be products of binary evo…

Low-degree solar rotational splitting from 45 years of BiSON observations

Rachel Howe, W. J. Chaplin, Y. P. Elsworth +2

We present solar low-degree rotational splitting values based on a new analysis of Sun-as-a-star observations from the Birmingham Solar Oscillations Network, covering a 16,425-day…

Detector bandwidth and polarisation switching rates: spectrophotometric observations of the Sun by the Birmingham Solar Oscillations Network (BiSON)

S. J. Hale, W. J. Chaplin, G. R. Davies +2

The Birmingham Solar Oscillations Network (BiSON) observes acoustic oscillations of the Sun. The dominant noise source is caused by fluctuations of Earth's atmosphere, and BiSON se…

The next generation Birmingham Solar Oscillations Network (BiSON) spectrophotometer: a new miniaturised instrument for helioseismology

S. J. Hale, W. J. Chaplin, G. R. Davies +2

We describe a new spectrophotometer for the Birmingham Solar Oscillations Network (BiSON), based on a next generation observation platform, BiSON:NG, a significantly miniaturised s…

Coralie radial-velocity search for companions around evolved stars (CASCADES) III. A new Jupiter host-star: in-depth analysis of HD 29399 using TESS data

C. Pezzotti, G. Ottoni, G. Buldgen +11

Context. Increasing the number of detected exoplanets is far from anecdotal, especially for long-period planets that require a long duration of observation. More detections imply a…

Signatures of magnetic activity in the seismic data of solar-type stars observed by Kepler

A. R. G. Santos, T. L. Campante, W. J. Chaplin +8

In the Sun, the frequencies of the acoustic modes are observed to vary in phase with the magnetic activity level. These frequency variations are expected to be common in solar-type…

Fast Rotating solar-like stars using asteroseismic datasets

R. A. García, T. Ceillier, T. Campante +27

The NASA Kepler mission is providing an unprecedented set of asteroseismic data. In particular, short-cadence lightcurves (~60s samplings), allow us to study solar-like stars cover…
