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…
Unraveling the Brown Dwarf Desert: Four New Discoveries and a Unifying, Period-Coded Picture
Ján Šubjak, Rafael Brahm, Jozef Lipták +30
We present four newly validated transiting brown dwarfs identified through TESS photometry and confirmed with high-precision radial velocity measurements obtained from the FEROS an…
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…
NGTS-11 c: a transiting Neptune-mass planet interior to the warm Saturn NGTS-11 b
David R. Anderson, Jose I. Vines, Katharine Hesse +56
We report the discovery of NGTS-11 c, a transiting warm Neptune ( d; ; ), in an…
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…
A transiting giant planet in orbit around a 0.2-solar-mass host star
Edward M. Bryant, Andrés Jordán, Joel D. Hartman +56
Planet formation models suggest that the formation of giant planets is significantly harder around low-mass stars, due to the scaling of protoplanetary disc masses with stellar mas…
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…
TOI-6478 b: a cold under-dense Neptune transiting a fully convective M dwarf from the thick disc
Madison G. Scott, Amaury H. M. J. Triaud, Khalid Barkaoui +25
Growing numbers of exoplanet detections continue to reveal the diverse nature of planetary systems. Planet formation around late-type M dwarfs is of particular interest. These syst…
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…
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…
The EBLM project -- XIII. The absolute dynamical masses of the circumbinary planet host TOI-1338/BEBOP-1
D. Sebastian, A. H. M. J. Triaud, M. Brogi +6
High-contrast eclipsing binaries with low mass M-dwarf secondaries are precise benchmark stars to build empirical mass-radius relationships for fully convective low-mass ($\rm M_{*…
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…
Saltire -- A model to measure dynamical masses for high-contrast binaries and exoplanets with high-resolution spectroscopy
Daniel Sebastian, Amaury H. M. J. Triaud, Matteo Brogi
High-resolution cross-correlation methods are widely used to discover and to characterise atomic and molecular species in exoplanet atmospheres. The characteristic cross-correlatio…
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…
