ASTEP confirmation of a pair of long-period Jupiter-sized planets with extremely low densities transiting TOI-791
Georgina Dransfield, Antoine C. Petit, Amaury H. M. J. Triaud +45
Gas giant planets with periods orbiting Sun-like stars are a relatively uncommon outcome of planetary formation, and key questions about the nature and form…
Bayesian analysis of Gaia epoch astrometry and radial velocities with kima
Thomas A. Baycroft, João P. Faria, Jean-Baptiste Delisle
Context. The next data release from the Gaia space telescope is expected to result in tens of thousands of newly detected exoplanets, as well as detection and 3D orbital constraint…
Uncovering the Rapidly Evolving Orbits of the Dynamic TOI-201 System
Ismael Mireles, Solène Ulmer-Moll, Donald Liveoak +47
Studying planetary interactions in exoplanet systems informs theories of planet formation and evolution, providing essential context for understanding our own solar system. We comb…
Predicting Gaia astrometry's ability to constrain the populations of circumbinary planets
Thomas A. Baycroft, Amaury H. M. J Triaud, Johannes Sahlmann
The coming data releases of Gaia are expected to result in an upheaval of exoplanet science, in particular for long period giant planets (…
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…
Polar alignment of a circumbinary disc around a brown dwarf binary
Jeremy L. Smallwood, Thomas A. Baycroft, Amaury H. M. J. Triaud +1
Inspired by recent observations suggesting that the retrograde precession of the brown dwarf binary 2M1510 AB is consistent with induction by a polar circumbinary planet, we invest…
EBLM XV -- Revised dynamical masses for the circumbinary planet host Kepler-16 AB, using the SOPHIE spectrograph
D. Sebastian, I. Boisse, A. Santerne +14
Eclipsing binaries are perfect laboratories to measure precise, accurate and model-independent stellar radii and stellar masses, so long as both components are spectroscopically re…
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…
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…
Progress report on the BEBOP search for circumbinary planets with radial velocities
Thomas A. Baycroft, Amaury H. M. J. Triaud, Dong Lai
The BEBOP (Binaries Escorted By Orbiting Planets) survey is a search for circumbinary planets using the radial velocity spectrographs HARPS and SOPHIE, currently focusing on single…
Detection of an Earth-sized exoplanet orbiting the nearby ultracool dwarf star SPECULOOS-3
Michaël Gillon, Peter P. Pedersen, Benjamin V. Rackham +81
Located at the bottom of the main sequence, ultracool dwarf stars are widespread in the solar neighbourhood. Nevertheless, their extremely low luminosity has left their planetary p…
A long-period transiting substellar companion in the super-Jupiters to brown dwarfs mass regime and a prototypical warm-Jupiter detected by TESS
Matias I. Jones, Yared Reinarz, Rafael Brahm +48
We report on the confirmation and follow-up characterization of two long-period transiting substellar companions on low-eccentricity orbits around TIC 4672985 and TOI-2529, whose t…
New methods for radial-velocity measurements of double-lined binaries, and detection of a circumbinary planet orbiting TIC 172900988
Lalitha Sairam, Amaury H. M. J. Triaud, Thomas A. Baycroft +8
Ongoing ground-based radial-velocity observations seeking to detect circumbinary planets focus on single-lined binaries even though over nine in every ten binary systems in the sol…
New evidence about HW Vir's circumbinary planets from Hipparcos-Gaia astrometry and a reanalysis of the eclipse timing variations using nested sampling
Thomas A. Baycroft, Amaury H. M. J Triaud, Pierre Kervella
The post common-envelope eclipsing binary HW Virginis has had many circumbinary companions proposed based on eclipse timing variations. Each proposed solution has lacked in predict…
GJ 9404 b: a confirmed eccentric planet, and not a candidate
Thomas A. Baycroft, Harry Badnell, Samuel Blacker +1
Eccentric orbits can be decomposed into a series of sine curves which affects how the false alarm probability is computed when using traditional periodograms on radial-velocity dat…
An M dwarf accompanied by a close-in giant orbiter with SPECULOOS
Amaury H. M. J. Triaud, Georgina Dransfield, Taiki Kagetani +40
In the last decade, a dozen close-in giant planets have been discovered orbiting stars with spectral types ranging from M0 to M4, a mystery since known formation pathways do not pr…
Improving circumbinary planet detections by fitting their binary's apsidal precession
Thomas A. Baycroft, Amaury H. M. J. Triaud, João Faria +2
Apsidal precession in stellar binaries is the main non-Keplerian dynamical effect impacting the radial-velocities of a binary star system. Its presence can notably hide the presenc…
