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…
First detection of oscillations in the Halo giant HD 122563: validation of seismic scaling relations and new fundamental parameters
Orlagh Creevey, Frank Grundahl, Frédéric Thévenin +8
The nearby metal-poor giant HD122563 is an important astrophysical laboratory for which to test stellar atmospheric and interior physics. It is also a benchmark star for which to c…
A Bootstrap Method for Sinusoid Detection in Colored Noise and Uneven Sampling. Application to Exoplanet Detection
Sophia Sulis, David Mary, Lionel Bigot
This study is motivated by the problem of evaluating reliable false alarm (FA) rates for sinusoid detection tests applied to unevenly sampled time series involving colored noise, w…
Science cases for a visible interferometer
Philippe Stee, France Allard, Myriam Benisty +54
High spatial resolution is the key for the understanding various astrophysical phenomena. But even with the future E-ELT, single dish instruments are limited to a spatial resolutio…
Asymmetries on red giant branch surfaces from CHARA/MIRC optical interferometry
A. Chiavassa, R. Norris, M. Montargès +14
Context. Red giant branch (RGB) stars are very bright objects in galaxies and are often used as standard candles. Interferometry is the ideal tool to characterize the dynamics and…
A study of periodograms standardized using training data sets and application to exoplanet detection
Sophia Sulis, David Mary, Lionel Bigot
When the noise affecting time series is colored with unknown statistics, a difficulty for sinusoid detection is to control the true significance level of the test outcome. This pap…
