A new photometric ephemeris for the 2M1510 AB double brown dwarf eclipsing binary system
Seb T. Millward, Vedad Kunovac
Eclipsing brown dwarfs are important calibrators of sub-stellar evolution models used to infer the characteristics of directly imaged brown dwarfs and giant exoplanets. Only two do…
Resolving star spots on WASP-85 A using high-resolution transit spectroscopy
Vedad Kunovac, Heather Cegla, Hritam Chakraborty +23
Stellar surface inhomogeneities such as spots and faculae introduce Doppler variations that challenge exoplanet detection via the radial velocity method. While their impact on disc…
RAVEN: RAnking and Validation of ExoplaNets
Andreas Hadjigeorghiou, David J. Armstrong, Kaiming Cui +5
We present RAVEN, a newly developed vetting and validation pipeline for TESS exoplanet candidates. The pipeline employs a Bayesian framework to derive the posterior probability of…
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…
The star HIP 41378 potentially misaligned with its cohort of long-period planets
S. Grouffal, A. Santerne, V. Bourrier +29
The obliquity between the stellar spin axis and the planetary orbit, detected via the Rossiter-McLaughlin (RM) effect, is a tracer of the formation history of planetary systems. Wh…
BEBOP V. Homogeneous Stellar Analysis of Potential Circumbinary Planet Hosts
Alix V. Freckelton, Daniel Sebastian, Annelies Mortier +29
Planets orbiting binary systems are relatively unexplored compared to those around single stars. Detections of circumbinary planets and planetary systems offer a first detailed vie…
The TESS SPOC FFI Target Sample Explored with Gaia
Lauren Doyle, David J. Armstrong, Daniel Bayliss +2
The TESS mission has provided the community with high-precision times series photometry for 2.8 million stars across the entire sky via the Full Frame Image (FFI) light curve…
The EBLM Project XI. Mass, radius and effective temperature measurements for 23 M-dwarf companions to solar-type stars observed with CHEOPS
M. I. Swayne, P. F. L. Maxted, A. H. M. J. Triaud +104
Observations of low-mass stars have frequently shown a disagreement between observed stellar radii and radii predicted by theoretical stellar structure models. This ``radius inflat…
The EBLM Project XII. An eccentric, long-period eclipsing binary with a companion near the hydrogen-burning limit
Yasmin T. Davis, Amaury H. M. J. Triaud, Alix V. Freckelton +17
In the hunt for Earth-like exoplanets it is crucial to have reliable host star parameters, as they have a direct impact on the accuracy and precision of the inferred parameters for…
Radial-velocity discovery of a second planet in the TOI-1338/BEBOP-1 circumbinary system
Matthew R. Standing, Lalitha Sairam, David V. Martin +24
We report the detection of a gas-giant planet in orbit around both stars of an eclipsing binary star system that also contains the smaller, inner transiting planet TOI-1338b. The n…
Measured Spin-Orbit Alignment of Ultra-Short Period Super-Earth 55 Cancri e
Lily L. Zhao, Vedad Kunovac, John M. Brewer +8
A planet's orbital alignment places important constraints on how a planet formed and consequently evolved. The dominant formation pathway of ultra-short period planets ( day)…
