BEBOP III. Observations and an independent mass measurement of Kepler-16 (AB) b -- the first circumbinary planet detected with radial velocities

Amaury H. M. J. Triaud, Matthew R. Standing, Neda Heidari +30

The radial velocity method is amongst the most robust and most established means of detecting exoplanets. Yet, it has so far failed to detect circumbinary planets despite their rel…

BEBOP II: Sensitivity to sub-Saturn circumbinary planets using radial-velocities

Matthew R. Standing, Amaury H. M. J. Triaud, João P. Faria +14

BEBOP is a radial-velocity survey that monitors a sample of single-lined eclipsing binaries, in search of circumbinary planets by using high-resolution spectrographs. Here, we desc…

The HD 137496 system: A dense, hot super-Mercury and a cold Jupiter

T. Azevedo Silva, O. D. S. Demangeon, S. C. C. Barros +28

Most of the currently known planets are small worlds with radii between that of the Earth and that of Neptune. The characterization of planets in this regime shows a large diversit…

HD207897 b: A dense sub-Neptune transiting a nearby and bright K-type star

N. Heidari, I. Boisse, J. Orell-Mique +90

We present the discovery and characterization of a transiting sub-Neptune orbiting with a 16.20 day period around a nearby (28 pc) and bright(V=8.37) K0V star HD207897 (TOI-1611).…

TOI-431/HIP 26013: a super-Earth and a sub-Neptune transiting a bright, early K dwarf, with a third RV planet

Ares Osborn, David J. Armstrong, Bryson Cale +125

We present the bright (V), multi-planet system TOI-431, characterised with photometry and radial velocities. We estimate the stellar rotation period to be $30.5 \pm…

The SOPHIE search for northern extrasolar planets. XVIII: Six new cold Jupiters, including one of the most eccentric exoplanet orbits

O. D. S. Demangeon, S. Dalal, G. Hébrard +28

Context. Due to their low transit probability, the long-period planets are, as a population, only partially probed by transit surveys. Radial velocity surveys thus have a key role…
