BEBOP VIII. SOPHIE radial velocities reveal an eccentric, circumbinary brown dwarf

Amaury H. M. J. Triaud, Thomas A. Baycroft, Neda Heidari +18

Circumbinary configurations offer a test of planet formation in an altered environment, where the inner binary has perturbed a protoplanetary disc. Comparisons of the physical and…

BEBOP VII. SOPHIE discovery of BEBOP-3b, a circumbinary giant planet on an eccentric orbit

Thomas A. Baycroft, Alexandre Santerne, Amaury H. M. J. Triaud +21

Planetary systems orbiting close binaries are valuable testing grounds for planet formation and migration models. More detections with good mass measurements are needed. We present…

Evidence for a polar circumbinary exoplanet orbiting a pair of eclipsing brown dwarfs

Thomas A. Baycroft, Lalitha Sairam, Amaury H. M. J Triaud +1

One notable example of exoplanet diversity is the population of circumbinary planets, which orbit around both stars of a binary star system. There are so far only 16 known circumbi…

Characterising M dwarf host stars of two candidate Hycean worlds

Lalitha Sairam, Nikku Madhusudhan

Planetary systems orbiting M dwarf host stars are promising targets for atmospheric characterisation of low-mass exoplanets. Accurate characterisation of M dwarf hosts is important…

BEBOP VI. Enabling the detection of circumbinary planets orbiting double-lined binaries with the DOLBY method of radial-velocity extraction

Lalitha Sairam, Thomas A. Baycroft, Isabelle Boisse +13

Circumbinary planets - planets that orbit both stars in a binary system - offer the opportunity to study planet formation and orbital migration in a different environment compare t…
