Efficient modeling of correlated noise-II. A flexible noise model with fast and scalable methods
JB Delisle, N Hara, D Ségransan - Astronomy & Astrophysics, 2020 - aanda.org
Correlated noise affects most astronomical datasets and to neglect accounting for it can lead
to spurious signal detections, especially in low signal-to-noise conditions, which is often the …

Efficient modeling of correlated noise-I. Statistical significance of periodogram peaks
JB Delisle, N Hara, D Ségransan - Astronomy & Astrophysics, 2020 - aanda.org
Periodograms are common tools used to search for periodic signals in unevenly spaced
time series. The significance of periodogram peaks is often assessed using false alarm …

A new method of correcting radial velocity time series for inhomogeneous convection
N Meunier, AM Lagrange, S Borgniet - Astronomy & Astrophysics, 2017 - aanda.org
Context. Magnetic activity strongly impacts stellar radial velocities (RVs) and therefore the
search for small planets. We showed previously that in the solar case it induces RV …

A study of periodograms standardized using training datasets and application to exoplanet detection
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 paper …

Overcoming the stellar noise barrier for the detection of telluric exoplanets: an approach based on hydrodynamical simulations
In 2015, we have celebrated the 20 th birthday of the first extrasolar planet discovered
around a solar-like star. Since then, several thousands of planets have been found. In this …
