We present an analysis of the transit timing variations (TTVs) in the multi-transiting planetary
system around Kepler-51 (KOI-620). This system consists of two confirmed transiting …

We present a detailed characterization of the Kepler-411 system (KOI 1781). This system
was previously known to host two transiting planets: one with a period of 3 days (R= 2.4 R⊕; …

During its four years of photometric observations, the Kepler space telescope detected
thousands of exoplanets and exoplanet candidates. One of Kepler's greatest heritages has …

Kepler-51 is a≲ 1 Gyr old Sun-like star hosting three transiting planets with radii≈ 6–9 R⊕
and orbital periods≈ 45–130 days. Transit timing variations (TTVs) measured with past …

The Kepler-11 planetary system hosts at least six transiting super-Earth planets detected
through the precise photometric observations of the Kepler mission (Lissauer et al.). In this …

Transit timing variations (TTVs) of Kepler-410Ab were already reported in a few papers.
Their semi-amplitude is about 14.5 min. In our previous paper, we found that the TTVs could …

As part of our follow-up campaign of Kepler planets, we observed Kepler-117 with the
SOPHIE spectrograph at the Observatoire de Haute-Provence. This F8-type star hosts two …

We present the discovery of the Kepler-19 planetary system, which we first identified from a
9.3 day periodic transit signal in the Kepler photometry. From high-resolution spectroscopy …
